Paleogeography is the scientific study and reconstruction of past geographic configurations of Earth’s surface, including the distribution of continents, oceans, mountain ranges, basins, and depositional environments through geologic time. It integrates data from plate tectonics, stratigraphy, paleomagnetism, sedimentology, paleontology, and geochronology to infer past positions and movements of tectonic plates and associated paleoenvironments. Paleogeographic reconstructions provide essential boundary conditions for paleoclimate modeling, basin analysis, sediment routing systems, and biogeographic studies, enabling quantitative assessment of how changes in Earth’s surface configuration have influenced climate systems, ocean circulation, biodiversity patterns, and the formation and distribution of natural resources.
This month, ESA's Mars Express takes us to Shalbatana Vallis: a fascinating Martian valley surrounded by signs of water, lava, craters and chaos. Shalbatana Vallis is an impressive channel near Mars's equator. This image, ...
