Lithologic, Paleogeographic, and Paleocurrent Maps of the World What are Paleocurrents? Why are they important? Paleocurrents are vectors indicating the direction of flow of currents depositing sediments on the earth's (or mars etc.) surface, in the past. Devonian Paleogeographic Map This is a BIG jpg image (1600x1200) These maps depict the distribution of lithologies, and the paleocurrents by geologic periods, and are based on nearly one million measurements worldwide. This information can be extremely helpful in attempting to reconstruct the past history of the earth. "For effort expended, measurements of directional structures are probably more rewarding to the field geologist than anything else".

Trilobite Paleogeography last revised 01 March 2002 by S. M. Gon III Biogeography involves the mapping and study of the patterns of distribution of organisms within and between the world's regions. The biogeography of plants and animals reflects their ecological requirements and the habitat niches they occupy. Some species are widespread, while others are restricted to certain regions of the globe. Paleogeography offers some of the same approach, but must take into account the fact of plate tectonics, and the changing of continental and ocean basin patterns over the course of hundreds of millions of years. The paleogeography of trilobites is particularly important because they were extremely diverse, were distributed all over the globe, and offer much insight on paleoenvironments. Trilobites occupied marine environments from tropical equatorial to polar paleolatitudes. Some families of trilobites were narrow in their requirements. For example, the family Bathyuridae (Proetida:Bathyuroidea) was found only in paleoequatorial regions. Trilobite marine niches ranged from intertidal and nearshore to deep continental slopes. Because there was very significant continental movement during the Paleozoic Era, with continents drifting apart, as well as converging and joining, the distribution and evolution of trilobites over the nearly 300 million years of their existence reflects a complex paleogeography. Why are the trilobites from Oklahoma and Morocco so similar?

Links THE PALEOGEOGRAPHIC ATLAS PROJECT UNIVERSITY OF CHICAGO About the Atlas Project We interpret paleogeography broadly to include all aspects of map reconstruction from paleo-continental orientations and tectonic considerations to the delineation of past topographic or bathymetric contours and the compilation of lithofacies data. In addition we use the reconstructions as base information for studies of past fossil distributions, and for climatic or oceanographic patterns as determined from the fossils, the sediments and from computer modeling studies. Our team has worked since the plate tectonic paradigm was introduced to compile information mainly from the literature on all aspects of global paleogeography. Moreover, we have pioneered the application of computer technology to paleogeographic map-making. click on image to enlarge The Paleogeographic Atlas Project in 2001 PGAP Publications (with links to abstracts) Jurassic slideshow sampler ( QuickTime ... Paleogeographic Maps (downloadable pdf files) Animations Successive paleogeographic maps often look very similar, just because continents move slowly in geologic time, mountains are uplifted gradually and shorelines generally do not advance or retreat significantly when viewed on a world scale. Animations are therefore necessary to bring out these subtle changes, and computer graphics are ideal for this purpose. Animations showing the general flow of the continental blocks through long intervals of geologic time are straightforward because the paleomagnetic information on the latitude and orientation of plates is reasonably well understood. Detailed paleogeographic maps, showing paleo-shorelines, and other paleogeographic contours are more problematic since depicting these accurately on closely spaced time steps is tedious and fraught with uncertainty. Nonetheless we have prepared a number of animations based on our detailed paleogeographic maps, and more are planned.

Middle Jurassic Paleogeography Paleogeography of the Southwestern US Images from a talk presented to the Annual Meeting of the Geological Society of America, Salt Lake City, Utah, Oct. 1997 Introduction The images presented here show the paleogeography of the SW US from 1.8 billion years ago to 10 million years ago. When played in order, the paleogeographic evolution of the region unfolds. Emphasis is on the Mesozoic where two or more images of each period are shown. Two different interpretations are presented for some of the periods. One shows a tectonic interpretation in which most elements of the western US were derived from North America; the second shows a tectonic interpretation in which some elements originated far from North America (exotic elements). Debate continues concerning these two different tectonic models. Paleogeographic Maps and Globes Text Precambrian Cambrian Ordovician ... Tertiary The images were prepared by placing various stratigraphic, tectonic, and sedimentologic data on a base map, plotting land vs. sea over this data, and then adding more detailed landforms such as mountains, shelf edges, rivers, arc-trench systems, and lowlands. The data was then painted in Photoshop 5.5. Climatic data is also added as tones of browns and reds for arid and greens for humid. The database for the images consists of many papers published on the geology of SW NAM. My own work is incorporated onto the Colorado Plateau portion of the maps. Plate patterns are from PGIS MAC, a plate-tectonic computer program by the Paleomap Project. Major sources of data are listed below:

Cretaceous Paleogeography, Southwestern US Early Cretaceous Paleogeography, Southwestern US (130 Ma). The Western Interior was the site of an encroaching epicontinental seaway from the north. To the west lay uplands and a thrust belt in Nevada and western Utah. Transtensional basins in southern Arizona and california were the sites of thick marine and continental deposition. The Cordilleran arc was now a classic continental (Andean-style) arc along all or most of its extent. The arc consisted of a fore arc-trench system, fore arc basin, and Andean arc. The fore arc-trench was the site of the famous Franciscan melange'. The Great Valley sequence was deposited in the fore arc basin and the Sierra Nevada batholith complex formed in the bowels of the arc Middle Cretaceous Paleogeography, Southwestern US (90 Ma). The Western Interior seaway has expanded to one of the greatest eoicontinental seas of all times. It stretched from central Utah to the western Appalachians and from the Arctic to the Gulf of Mexico. The Sevier orogenic belt bordered the sea to the west. This great thrust belt resulted from compression of the Cordilleran arc, perhaps further mitigated by collision with the huge Wrangellia oceanic plateau. The nature of the collision, its exact location, and its magnatude are anything but clear. Pieces of Wrangellia and Wrangellia-like plateaus are presently strewn along the west coast of North America from Mexico to Alaska Late Cretaceous Paleogeography, Southwestern US (75 Ma). The Western Interior seaway slowly retreated to the northeast. Vast alluvial plains marked its past locations. Some of the World's greatest dinosaur remains are found in these deposits. The Sevier orogeny was at its climax. Regional metamorphism affected western Arizona and eastern California. Paleozoic and Mesozoic sandstone, mudstone, and limestone were metamorphosed to quartzite, schist, and marble. The west coast was marked by strongly oblique collision between the oceanic and continental plates and right-lateral transform faults transported pieces of Wrangellia and other terrains northward along the edge of North America. The Franciscan forearc complex was a broad accretionary prism that was constantly being deformed by complex stresses into a melange'

The strait also features prominently in the environmental history of Beringia in that it has been largely absent during the region's late Quaternary history. Global (eustatic) sea levels lower than today left the area exposed forming the Bering Land Bridge. The closing of this land bridge over the last 21,000 years is one of the dramatic changes in the Beringian landscape seen over this period.

paleogeography Paleogeography, the study of the Earth's past geography, is a major subfield of historical geology. Relying on a broad spectrum of information made available from many other fields in geology and the natural sciences, it analyzes, interprets, and synthesizes the former configuration and distribution of oceans and lands, mountains and plains, climatic belts, paleobiological provinces, paleoecological conditions, and many related features. Early Concepts Development of paleogeography has proceeded along several courses. Charles LYELL, in his Principles of Geology (1830-33), stated that every part of the land had once been beneath the sea and that every part of the ocean had once been land, in an endless cycle from land to sea and back again. This dramatic statement, designed to loosen the rigid concepts of geography then prevalent, was defensible only for the land surface; knowledge of the oceans would remain too sparse for more than 125 years after that time. Only recently have studies revealed that the ocean basins have had a different history than that proposed by Lyell (see OCEAN AND SEA). Dana believed that the Earth was coolinga common hypothesis of the 1800s and early 1900sand therefore that the Earth's surface was shrinking. He believed that this shrinking, like a shriveling orange skin, was the cause of most of the structural deformation of the Earth's crust. Dana considered (1856) the amount of deformation at the margins of the continents to be proportional to the size of the adjacent oceanfor example, the Atlantic margin of North America is less mountainous than the Pacific margin. He reasoned that the continents were fixed in position and that the ocean areas pushed against them with a force proportional to the area of the ocean. Unfortunately, this concept of fixity of continents and ocean basins was not based on an accurate geological understanding of continental-ocean margins.
