| Summary: | The article presents an overview of published lithological, sedimentological, geochemical, paleontological, paleogeographic, paleobiogeographic, paleoclimatic data on the Lower Jurassic deposits of Europe, Central Asia and Siberia. As a result of the analysis and integration of these materials, the paleogeographic sketch maps of the Northern Eurasia land for the Hettangian, Sinemurian, Pliensbachian and Toarcian were refined and detailized, which reflect the main changes in accumulative and denudational landscapes. Sketch maps of climatic zoning for this area have been compiled. In Europe, during the Early Jurassic, the continental settings were gradually replaced by shallow-marine environments. A warm, predominantly humid, subtropical climate prevailed. Siberia in the first half of the Early Jurassic, was characterized by landscapes, where denudation prevailed over accumulation. In the second half of the Early Jurassic, a series of marine transgressions occur in the north of Siberia, while in the south, the area of continental sedimentation reaches its maximum extension. There was a high-latitude moderately warm climate with a pronounced change of polar days and nights. During the Early Jurassic, the temperate and subtropical climatic zones came into contact on the area of Central Asia. The resulting maps can be used in paleobiogeographic research. |
