Sedimentation History and Provenance Analysis of a Late Mesozoic Rifting Event at Tavan Har, East Gobi, Mongolia
Davidson, Sarah Cain
Frontiers: The Interdisciplinary Journal of Study Abroad, v12 p91-122 Nov 2005
The East Gobi Basin (EGB), which covers over 1.5 million square kilometers in southeastern Mongolia, is one of several basins in eastern China and Mongolia that was formed by extension and intracontinental rifting during the late Mesozoic. For reasons that are poorly understood, the continental lithosphere covering areas that are now known as eastern China and Mongolia underwent extension and thinning, which led to normal faulting and the creation of areas of subsidence--basis--within the continent. This study contributes to the amount of primary field data and quantitative analyses available on the Mesozoic sedimentary deposits within the EGB, focusing on the syn-rift rock units that were extensive in our particular field area. This is the first study to focus on the source rock of sandstones in the EGB. In addition, the data provide a basis for reconstructing the paleogeography and paleoenvironment of late Mesozoic rifting event. The conclusions of this study, when placed within the context of the geology of Asia, help readers to better understand rift processes and basin evolution in different parts of the world.
