Sedimentary characteristics and evolution of Paleogene Lower Xiaganchaigou Formation in northern Mahai area, northern margin of Qaidam Basin
Online published: 2011-12-20
Based on the analysis of sedimentary sequence, cores, grain size, well logging data, the sedimentary characteristics and evolution of Lower Xiaganchaigou Formation of Paleogene in northern Mahai area，northern margin of QaidamBasin，were studied. The result shows that the Lower Xiaganchaigou Formation displays an obvious regression, and the sedimentary facies is mainly braided fluvial facies. The study on sedimentary systems demonstrates the sedimentary facies distribution and evolution rule more clearly, which provides reliable geologic information for the next exploration activity.
