The simplest kind of paleogeography is a map showing the locations of ancient lands and seas, but paleogeographic maps may also show the occurrence and distribution of fossil, plant, and animal communities; environments of sedimentation (e.g., deltas, reefs, deserts, or deep-sea basins); areas undergoing uplift and erosion or subsidence and deposition; and major climatic zones. document.writeln(AAMB2); Images and Media: More on "paleogeography" from the 32 Volume paleogeography - the ancient geography of Earth's surface. Earth's geography is constantly changing: continents move as a result of plate tectonic interactions; mountain ranges are thrust up and erode; and sea levels rise and fall as the volume of the ocean basins change. These geographic changes can be traced through the study of the rock and fossil record, and data can be used to create paleogeographic maps, ... Cretaceous Period - The position of Earth's landmasses changed significantly during the Cretaceous Period-not unexpected, given its long duration. At the onset of the period there existed two supercontinents, Gondwana in the south and Laurasia in the north. South America, Africa (including the adjoining pieces of what are now the Arabian Peninsula and the Middle East), Antarctica, Australia, India, Madagascar, and ...

The convention used on this page is to indicate radiocarbon dates in lower case letters (bc), versus the use of upper case letters (BC) for alternate dating estimates. The Ice Ages Caught in the ebb and flow of the last Ice Ages over the last 2 million years, Ireland was at various times largely glaciated and completely land-locked as a part of the continent of Europe. Ireland was an island about 125,000 years ago when the sea level appears to have been very close to its present position. The sea level dropped 130 m (426 feet) or more during the interval from around 30,000 to 15,000 years ago, when Ireland became part of continental Europe [again], and sea levels have been generally rising ever since, albeit at a much slower rate. The image to the left represents the land mass of Europe near the time of the last glacial maximum (minus the ice sheets and the ocean water). Take a close look at the "British peninsula" and the outline of Ireland and Great Britain upon it.

Poster 1 Poster 2 Poster 3 Poster 4 Tropical versus Temperate Zone Lacustrine Source Rocks: Examples from Takutu Basin, Guyana, and General Levalle Basin, Argentina by Robert E. Webster Search and Discovery Article #10070 (2004) *Adapted from a poster presentation at AAPG Annual Convention, Dallas, Texas, April 18-21, 2004. Hunt Oil Company, Dallas, Texas ( bwebster@huntoil.com Abstract Rift basin lacustrine source rocks have generated 5.7 percent of the world’s reserves, and some of today’s most active exploration plays are driven by lacustrine-shale-based petroleum systems. However, paleolatitude and paleoclimate play major roles in determining organic richness of lake sediments, and not all restricted lacustrine basins contain commercial petroleum systems. Two continental-interior lacustrine rift basins in South America display dramatic differences. In the Takutu basin, at a tropical paleolatitude of 2°N, deposition in an Early to Middle Jurassic rift during global “hothouse” conditions produced organic-rich shale with 1.5 to over 4% TOC, hydrogen indices of over 360, and pyrolysis yields up to 9300 ppm. Terrestrial kerogen is significant, but Type I/II non-marine algal amorphous kerogen is dominant in richer intervals. Significant oil and gas were generated but mostly lost during Miocene(?) tectonic reactivation. In contrast, the Lower Cretaceous General Levalle rift basin formed at a temperate zone paleolatitude of 45°S during mild “icehouse” climatic conditions. Dark lacustrine shale is organic-lean, with maximum TOC just over 1%. Kerogen is Type III/IV, derived mostly from pollen from nearby upland forests, with little generative capacity. Here the annual seasonal cycle probably caused lake turnover and prevented long-term establishment of an anoxic bottom layer to preserve organic matter, which is common in more tropical settings such as the Takutu.

50. Geol 02C Paleogeography And Paleomagnetism Lecture This practice is called paleogeography and is succeeding in producing a remarkable view of the evolving geography of the Earth. http://people.hofstra.edu/faculty/j_b_bennington/2cnotes/paleogeography.html

Geol 02C Historical Geology J Bret Bennington Paleogeography and Paleomagnetism Paleomagnetism remnant magnetism in rock. Remnant magnetism Polarity - The overall North-South orientation of the remnant magnetic field in the rocks. This can be either normal (as it is today) or reversed (with north and south magnetic poles changing places.) Magnetic reversals Declination - Like a compass needle, a remnant magnetic field also points in a straight line toward the magnetic pole. Dip To summarize, the remnant magnetic field in a rock gives an indication of the direction to the magnetic pole and the latitudinal distance from the pole when the rock was magnetized. Unfortunately, nothing about remnant magnetism gives any indication of longitude (i.e. the position around the circumference of the Earth). Wandering Poles wandered in the past, occupying positions far from its present location. However, an observation soon developed that cast doubt on the theory of polar wandering. When the polar wander paths obtained from rocks in North America and from rocks in Britain were compared, they were found to be different - as if to suggest that the magnetic pole had been in two different places at the same time in the past. Clearly, this was impossible. The solution to this puzzle was obtained when North America and Europe were adjusted on a map to connect to one another along the mid-Atlantic ridge. Assuming that the two continents were once joined brought the polar wander paths together until about the Jurassic - just when Wegener had suggested that they had begun to drift apart!
