In this paper, the characteristics of Batamayineishan Formation of Carboniferous volcanic rocks in Dixi area were studied in detail. The features of rock cores, thin sections and response of well logging were analyzed. A suit of methods for identifying the lithology were presented. The seismic response characteristics of typical combined rocks were summarized and the distribution of dominant lithology was predicted. The research shows that the distribution of volcanic rocks can be divided into 3 segmentations, the east, the centre and the west. The east segment is mainly acidic volcanic rocks, the west segment is mainly basic volcanic rocks, and the basic, intermediate and acidic volcanic rocks are all well developed in the centre segment.
