Primary source references As a preface to this document, I want to point out that it is a shame that we have to continue to refute the same arguments that evolutionists keep bringing up over and over again in their attempts to argue against the fact of creation, which fact has been well established since the day the earth was created ex nihilo several thousand years ago. It is also a shame that the masses have bought all this based on some circular reasoning about fossils, where fossils tend to be found buried, similarities between various life forms, the presence of certain decay products in rocks, and other inherently speculative arguments about the past, based on phenomena that exist in the present. If I hope to accomplish anything, it will be to simply encourage critical thinking. One must get past the arguments ad populum that its popularity counts for something , ad hominem that if you attack the person making the argument, this counts for something , and especially ad baculum that there are people who have the clout to decree it as true , to ask the key questions and challenge the unsubstantiated assumptions and thinking of those who would hold to the evolution position. Today there are an increasing number of anti-creationist authors who are producing books and periodicals that make this relatively brief presentation insufficient to deal with all the points in dispute. Those defending creation today who don’t have the time to devote their life’s study to gaining expertise in all fields of inquiry must principally be prepared to think critically, logically, and challenge unsubstantiated assumptions made by these people. They must also keep a level head in the face of some vicious attacks and diatribes that will be directed against them, as is advised in the scriptures 1 Peter 3: By way of definitions, I want to point out that when I speak of “evolution,” I am referring to the popular contemporary use of the word, which in a nutshell is the belief that all life forms are related by ancestry, and that the first life form occurred spontaneously, all due to completely natural processes. When I speak of “creation,” I am referring to the inherently obvious fact that the origin of all life forms can be attributed to a creator who purposefully created them with planning and intent, and the documented fact that this occurred over the course of a week’s time several thousand years ago.

Rest and satisfaction In light of these correspondences, Kline interprets days one and four as different perspectives on the same event, and likewise days two and five, and three and six. He concludes that while the creation account is historical, historicity and narrative sequence are not the same thing, so the account need not—indeed, should not—be read as chronological at all.

Chronological Methods 11 – Paleomagnetic and Archaeomagnetic Dating After World War II, geologists developed the paleomagnetic dating technique to measure the movements of the magnetic north pole over geologic time. In the early to mid s, Dr. Robert Dubois introduced this new absolute dating technique to archaeology as archaeomagnetic dating. How does Magnetism work? Magnetism occurs whenever electrically charged particles are in motion.

The Earth’s molten core has electric currents flowing through it. As the earth rotates, these electric currents produce a magnetic field that extends outward into space. This process, in which the rotation of a planet with an iron core produces a magnetic field, is called a dynamo effect. The Earth’s magnetic core is generally inclined at an 11 degree angle from the Earth’s axis of rotation.

Therefore, the magnetic north pole is at approximately an 11 degree angle from the geographic north pole. On the earth’s surface, when you hold a compass and the needle points to north, it is actually pointing to magnetic north, not geographic true north.

The earth’s magnetic field: evidence that the earth is young

General Questions What is the Earth’s magnetic field? The Earth acts like a large spherical magnet: The field is generated by a dipole magnet i. The axis of the dipole is offset from the axis of the Earth’s rotation by approximately 11 degrees. This means that the north and south geographic poles and the north and south magnetic poles are not located in the same place.

Introduction. Dinosaurs bring wonder to children and adults alike. That such great beasts once roamed the earth is hard to imagine. Even harder to imagine is that some dinosaurs such as Tyrannosaurus rex were probably giant killing machines (after the Fall, anyway). Of all the many questions related to dinosaurs, their disappearance from the earth is the most mysterious of all.

Eocene My And here’s the tree All the names on the tree are genus names, so recall that each genus encompasses a cluster of closely related species. The is a brief description of the tree for those who are visually impaired. Hyracotherium is shown giving rise to three lineages. Two lineages quickly go extinct. The third branches many times. There are many branches alive during most times until two million years ago when only the various species of Equus remain.

This is an excellent design feature of our planet: It is also powerful evidence that the earth must be as young as the Bible teaches. Barnes calculated that the current could not have been decaying for more than 10, years, or else its original strength would have been large enough to melt the earth.

March 17, ] Contents Artiodactyls cloven-hoofed animals “The early evolution of the artiodactyls is fairly well documented by both the dentition and the skeletal material and provides the basis for fairly detailed analysis of evolutionary patterns Has many tooth features linking it to later Diacodexis; but in all other ways, including the legs, it was an unspecialized condylarth. No artiodactyl fossils known from the late Paleocene. Similar late Paleocene gaps in rodents, lagomorphs, and perissodactyls are currently being filled with newly discovered Asian fossils, so apparently much late Paleocene herbivore evolution occurred in central Asia.

Perhaps the new Asian expeditions will find Paleocene artiodactyl fossils too. Diacodexis early Eocene — A rabbit-sized with longer limbs than the condylarths. The fibula was reduced to a splint, and in some but not all! Artiodactyl-like “double pulley” ankle because of this feature, Diacodexis is automatically classified as the first artiodactyl. The feet were very elongated, and the 3rd and 4th toes bore the most weight. Many primitive, non-artiodactyl features retained: In fact, in most ways, Diacodexis is just a leggy condylarth.

Only the ankle shows that it was in fact the ancestor of all our modern cloven-hoofed animals possible exception: There are abundant species-to- species transitions linking Diacodexis to various artiodactyl familes see below.

Human timeline and Nature timeline There has been some debate as to when and whether Vaalbara existed. Button, however, placed Madagascar between Africa and Australia and concluded that Gondwana must have had a long stable tectonic history. In Rogers’ reconstructions, however, Kaapvaal and Pilbara are placed far apart already in their Gondwana configuration, a reconstruction contradicted by later orogenic events and incompatible with the Vaalbara hypothesis.

In the reconstruction of Wingate they fail to overlap, but they do in more recent reconstructions, for example Strik et al. Zimgarn should have disintegrated around 2. Grunehogna collided with the rest of East Antarctica during the Mesoproterozoic assembly of the supercontinent Rodinia and the Grenville orogeny.

Even with these assumption paleomagnetic dating is a useful tool for dating geologic objects. Due to its inherent ability to date essentially all rock types in a variety of geologic settings, paleomagnetic dating is particularly useful for areas with sparse or uncertain isotopic or biostratigraphic age constraints.

Abstract Documenting the early tectonic and magmatic evolution of the Izu—Bonin—Mariana IBM arc system in the Western Pacific is critical for understanding the process and cause of subduction initiation along the current convergent margin between the Pacific and Philippine Sea plates. Ocean floor drilling International Ocean Discovery Program Expedition recovered basement-forming, low-Ti tholeiitic basalt crust formed shortly after subduction initiation but distal from the convergent margin nominally reararc of the future IBM arc Amami Sankaku Basin: Radiometric dating of this basement gives an age range Similarity in age range and geochemical character between the reararc and forearc basalts implies that the ocean crust newly formed by seafloor spreading during subduction initiation extends from fore- to reararc of the present-day IBM arc.

Given the age difference between the oldest forearc basalt and the ASB crust, asymmetric spreading caused by ridge migration might have taken place. This scenario for the formation of the ASB implies that the Mesozoic remnant arc terrane of the Daito Ridges comprised the overriding plate at subduction initiation. The juxtaposition of a relatively buoyant remnant arc terrane adjacent to an oceanic plate was more favourable for subduction initiation than would have been the case if both downgoing and overriding plates had been oceanic.

History[ edit ] In the early 20th century, geologists first noticed that some volcanic rocks were magnetized opposite to the direction of the local Earth’s field. The first estimate of the timing of magnetic reversals was made by Motonori Matuyama in the s; he observed that rocks with reversed fields were all of early Pleistocene age or older. At the time, the Earth’s polarity was poorly understood, and the possibility of reversal aroused little interest. Most paleomagnetic research in the late s included an examination of the wandering of the poles and continental drift.

Although it was discovered that some rocks would reverse their magnetic field while cooling, it became apparent that most magnetized volcanic rocks preserved traces of the Earth’s magnetic field at the time the rocks had cooled.

Geochronology – Nonradiometric dating: In addition to radioactive decay, many other processes have been investigated for their potential usefulness in absolute dating. Unfortunately, they all occur at rates that lack the universal consistency of radioactive decay. Sometimes human observation can be maintained long enough to measure present rates of change, but it is not at all certain on a.

In this article we shall discuss how we can use the paleomagnetism in rocks to attach dates to them paleomagnetic dating. The reader may find it useful to go back and read the main article on paleomagnetism before continuing. Polar wander and dating[ edit ] Once we have dated a sufficient number of rocks and measured the orientation of the magnetism they contain, we can build up a picture of how the position or apparent position of the poles over time.

So if we are then faced with a rock the date of which we do not know, then we do know of course the latitude and longitude at which we found it, and we can measure the orientation of its magnetism, and so we can look at the global picture we’ve built up of continental drift , and to figure out when the rock must have formed in order to have its magnetism oriented in just that direction. Magnetic reversals and dating[ edit ] Once we have dated a sufficient number of rocks and found out whether they have normal or reverse polarity , we can likewise build up a timeline for the occurrence of the reversals.

As noted in a previous article , magnetic reversals come at irregular intervals. This means that the pattern of normal and reverse polarity in an assemblage of rocks can be distinctive in the same way though for a completely different reason that growth rings in a tree can be distinctive. We might, for example, see a long period of reverse polarity, followed by six very quick switches of polarity, followed by a long period of normal polarity; and this might be the only time that such a thing occurs in our timeline.

So if we are presented with an undated rock, and we find a really distinctive pattern of paleomagnetic reversals within it, we may be able to identify the one time at which such a sequence of magnetic reversals took place. Strengths and weaknesses of the method[ edit ] The reader will observe that it is necessary to be able to date some rocks, in fact a lot of rocks, before paleomagnetic dating can be brought into play. You may therefore be wondering why, if we have perfectly good dating methods already, we don’t just use them.

Paleoclimate Numerical climate models as well as carbon isotope measurements from preserved Ordovician soils suggest that atmospheric levels of carbon dioxide during the period were 14—16 times higher than today. These high levels were driven by widespread volcanic activity , which would have released large volumes of carbon dioxide into the atmosphere. The extensive flooding of continents due to high sea levels, combined with the lack of widespread vegetation on land, would have suppressed the weathering of silicate rocks, a major mechanism for removing carbon dioxide from the atmosphere.

In short, the rate at which carbon dioxide was added to the atmosphere increased during the Ordovician Period, whereas its rate of removal decreased. Because of the greenhouse effect , high levels of atmospheric carbon dioxide would have caused temperatures to rise everywhere from the Equator to the poles. Clear evidence of warm temperatures in the tropics can be seen in the extensive Ordovician limestone deposits with features similar to those found in modern tropical carbonate areas, such as the coral reefs of the Bahamas.

Other evidence suggesting warm low-latitude climates in the Ordovician include bauxite deposits in Kazakhstan and evaporite minerals in North America , Australia, China , Kazakhstan, and Siberia. Warm tropical regions would have fostered the development of tropical cyclones ; there is a rich record of such storms in the Ordovician. In subtropical areas of North America, sedimentary deposits from Ordovician continental shelves commonly occur in alternating beds of shale and either sandstone or limestone.

Historical Geology/Paleomagnetic dating

The Paleogeographic Method The study of paleogeography has two principle goals. The first goal is to map the past positions of the continents. The second goal is to illustrate the changing distribution of mountains, lowlands, shallow seas, and deep ocean basins through time. Mapping the Past Positions of the Continents The past positions of the continents can be determined using the following five lines of evidence: By measuring the remanent magnetic field often preserved in iron-bearing rock formations, paleomagnetic analysis can determine whether a rock was magnetized near the Pole or near the Equator.

Paleomagnetism provides direct evidence of a continent’s N-S latitudinal position, but does not constrain its E-W longitudinal position.

A geomagnetic reversal is a change in a planet’s magnetic field such that the positions of magnetic north and magnetic south are interchanged (not to be confused with geographic north and geographic south).The Earth’s field has alternated between periods of normal polarity, in which the predominant direction of the field was the same as the present direction, and reverse polarity, in which it.

There is a flourishing of Oldowan tools in eastern Africa, spreading to southern Africa, between 2. Both technologies are occasionally found in the same areas, dating to the same time periods. This realisation required a rethinking of old cultural sequences in which the more “advanced” Acheulean was supposed to have succeeded the Oldowan. The different traditions may have been used by different species of hominins living in the same area, or multiple techniques may have been used by an individual species in response to different circumstances.

In China, only “Mode 1” Oldowan assemblages were produced, while in Indonesia stone tools from this age are unknown. The earliest Acheulean sites in Europe only appear around 0.
