Rising postglacial seas have flooded the world’s continental shelves, limiting our ability to reconstruct human migrations, the history of settlement along Pleistocene coastlines, and the antiquity of coastal shell middens. This includes the southern coast of Beringia, where dramatic landscape changes make it difficult to test the coastal migration theory, which proposes that Upper Paleolithic ...

[1] The causes for the Permian‐Triassic Boundary (PTB) extinction, the largest mass extinction on record, remain enigmatic. The period is marked by large‐scale volcanic eruptions and evidence for widespread ocean anoxia, which have led to suggestions that these events generated, or played a part in, the extinction. Furthermore, hypercapnia and ocean acidification caused by volcanic emissions of...

The Taiyuan Formation, located on the northern margin of Ordos Basin, has an important role in reconstructing tectonic paleogeography and evolutionary process due to its preservation information about evolution basin throughout Late Paleozoic. provenance, paleogeography, activity traits Formation were examined using sedimentary petrology zircon chronology methods. Alxa block is consistent with ...

Knowledge of reservoir distribution and quality in the offshore eastern Gulf of Mexico (EGOM) is essential for future economic development of hydrocarbon resources. The Norphlet Fm. has been a significant hydrocarbon reservoir in the onshore EGOM region since the late 1960’s; however, due to sparse lithologic data in the offshore EGOM, predicting Norphlet Fm. reservoir distribution in this area...

It is clearly proposed that “lithofacies paleogeography can be used as a guide for shale gas geological survey work”. Lithofacies not only the theoretical guidance of work, but also its related mapping technology method key to “find” gas.
