Santanghu Basin is located in Xinjiang, northwest China, where developed huge area and various system of igneous rock formations. The conventional log data and ECS (Elemental Capture Spectroscopy) data are analyzed. Combined with the rock section analysis and sample log data, the log response characteristics of basalt, andesite, tuff, diabase, sandstone and mudstone in the study area are summed up. The physical quantities and parameters sensitive to igneous rock lithology are selected tomake crossplot for lithology identification. A set of lithologic chart suitable for this area is set up and the log parameters for different lithologies are determined.
