Features of Karst Paleogeomorphology and Sedimentary Environment of Ordovician Majiagou Formation in Eastern Ordos Basin [PDF]

ACS Omega
The formation and evolution of carbonate weathering crust-type reservoirs are closely linked to paleokarst processes. This study aims to restore and analyze the karst paleogeomorphology and sedimentary environment of the Ma2 and Ma3 sections in the eastern Ordos Basin, using the compensation thickness impression method. The Ma3 section is characterized
