Palaeogeography From Wikipedia, the free encyclopedia Jump to: navigation search Paleogeographic reconstruction showing the Appalachian Basin area during the Middle Devonian period. Palaeogeography (also spelled paleogeography ) is the study of what the geography was in times past. It is most often used about the physical landscape , although nothing excludes its use in reference to the human or cultural environment. If the topic is landforms it could also be called paleogeomorphology. In petroleum geology the term paleogeographic analysis is used for the detailed study of sedimentary basins , since the ancient geomorphological environments of the Earth 's surface are preserved in the stratigraphic record. Paleogeographers also study the sedimentary environment associated with fossils to aid in the understanding of evolutionary development of extinct species. The reconstruction of prehistoric continents and oceans depends partly on paleogeographic evidence. Thus paleogeography provides critical evidence for the development of continental drift and current plate tectonic theories. For example, knowledge of the shape and latitudinal location of

3. Paleogeography Of The Bahamas And The Columbus Landfall Question Site focuses on the integration of paleoclimatic, geological and historical data of hemispheric, regional and local scale to elucidate past environmental conditions in the Bahamas http://www.angelfire.com/sc3/paleogeography/

Paleogeography of the Bahamas and the Columbus Landfall Question The first encounter of the Old World with the New World occurred on October 12, 1492, on an island called Guanahani by its native inhabitants and christened San Salvador by Christopher Columbus. Columbus described it as "quite large, and very flat, and with very green trees and many waters and a very large laguna in the middle." No other landfall in recorded history compares in importance, as it was here that monumental global changes were set in motion. The identity of this Bahamian island and of the others visited by him before reaching Cuba, remains enigmatic. Beyond commemorative considerations, the inability to determine wherein the ethnographic and environmental observations made by Columbus apply, significantly hinder our ability to fully utilize this earliest American historical record.

Hållbarhetsindex Diskussion Links Links Press Atlantis Explained? You be the judge. Atlantis is a place Plato described in Timaios and Kritias as an example in a discourse on how society could be organized. This website accompanies the book on the right, but also contains much other material especially in Swedish (book-length treatises on European DNA and paleogeography). This site deals with two issues relating to Plato's Atlantis: 1. The topos of Atlantis: what, if anything, did he base it on? 2. The lesson of Atlantis: what, if anything, can we learn from this? While the second issue is surely the more interesting one, one can not approach it without first dealing with the first. The approach used by self-proclaimed "sceptics" is to instead pose the question if Atlantis is fact or fiction, and reply that it is fiction. However, that is a false dilemma : the reply is given beforehand by the nature of the question (their question is actually, "is everything true, or is there any detail that is false?," so it follows by necessity what the answer will be; scepticism is necessary, but so is fantasy in the thought process).

HOME GLOBAL PALEOGEOGRAPHY REGIONAL PALEOGEOGRAPHY COLORADO PLATEAU ... PUBLICATIONS Global Paleogeography Introduction The global views presented in this series show how Earth may have appeared over the last 600 million years (Ma). All views were prepared from rectangular projections drawn at a resolution of 3000x1500 pixels for each of the 26 time slices. The orthographic (spherical) and Mollweide (oval) were wrapped using the respective projections. Topography was "cloned" from digital elevation maps of modern Earth from the USGS. Colors were adjusted to portray climate and vegetation for the given time and location. The modern Earth was also drawn in this manner using a color pallet derived from satellite images created by ARC Science of Loveland, Colorado. The geologic data was gathered from the references listed below. Mollewide globes 27 global time slices in mollewide projection Paleogeographic globes 26 global time slices, many with 2 or 3 views.

Durango Bill's Paleogeography (Historical Geology) Research Unaweep Canyon cuts across the Uncompahgre Plateau (about 20 miles south of Grand Junction, Colorado) View looking north where Unaweep Canyon cuts across the Uncompahgre Plateau. Contour intervals are 100 feet. Today there is no river in this canyon. The high saddle point within the canyon (just northwest of the Gill Creek label) forms a divide with local drainage flowing down each side. However, up to about 7 or 8 million years ago, a large river flowed from east-northeast (right) to west-southwest (left) through this canyon. As mentioned above, the highest point within Unaweep is just northwest of the Gill Creek label. West of the high point, the gradient is only gradually downhill for the first 15 miles indicating the ancestral river abandoned this route before canyon cutting from the Grand Canyon event had backed up this far. (Otherwise it would have rapidly cut down through the west side of the Uncompahgre Plateau.) This means the canyon had to be abandoned at least 4-5 million years ago. On the other hand, the canyon walls appear to have undergone little erosion which means it can't be very old. A ballpark estimate would indicate that a river was here less than 10 million years ago. Thus we get an estimated age of 7 (+/- 3) million years ago when the canyon was abandoned Prior to 30 million years ago, the ancestral Colorado River flowed north from Colorado into Wyoming. About 25 to 30 million years ago the Rabbit Ears Range rose in northern Colorado blocking the former path of the ancestral Colorado River. The river turned westward and established a new route across this area. The Gunnison River joined the ancestral Colorado on the east side of Unaweep Canyon just to the northwest of Cactus Park (off the right edge of the picture).

By clicking through the slides, you can see how the continents moved and formed in the distant past (the Fade Slow slide transition is important for the effect).

North America Paleogeography (6.1 MB Powerpoint Show file) These maps are centered on North America Southwest U.S. Paleogeography (4.6 MB Powerpoint Show file) This shows the (speculative) development of the southwest U.S. starting about 1.7 million years ago. You can watch island arcs "crash" into the ancient continent, and the coming and going of the inland seas that were the basis of much of the sedimentary rock in that area. The current location Grand Canyon is denoted by a yellow circle, and helps illustrate why the Canyon has such an abundance of different strata, being often on the margins of those seas.

Fossil magnetism in rocks is misaligned with the Earth's present magnetic field, and shows that the continents have moved; it indicates the orientation and latitude of a continent at the time when the rocks were formed. This is the primary source of information about the past locations of continents, but it gives no indication of longitude. Good evidence of recent movements comes from the growth of ocean floors. Traces of ancient oceans, found among mountains, announce that different pieces of present continents were formerly separated, while evidence of rifting along shore-lines indicates that continents have split asunder. Edges can be put together again by computer programs that reconcile the coarse shapes of continents with the precise geometry of motions on a sphere, to obtain best fit... The continents can, though, be dismembered into microcontinents, and maps adjusted by evidence of connections and splits between organisms, climate as indicated by characteristic rocks (e.g., coal, or fossil sand dunes), and geological activity. Global patterns of climate and ocean circulation can be inferred...Continental arrangements before 6oo My ago are hazy and controversial, although the existence of earlier supercontinents [similar to Pangea ] is presumed Nigel Calder
