Abstract: This study area is located in Zhusileng-Hangwula structure belt. Based on the distribution and contact relation of volcanic rocks and the zircon U-Pb age (333.5±3) Ma of granite in later intrusive rocks, it can be judged that these volcanic rocks were formed in middle stage of early Carboniferous (it's about Visea Stage of Mississippian Epoch); Combined with features of regional comparison and the above discussion, these volcanic rocks have been placed as the Lower Carboniferous Baishan Formation. In this paper, the sixteen samples of volcanic rock have been systematically collected, and the analysis date of these samples showed that they are Calc-alkaline series and medium-acid volcanic rocks. The trace elements spider diagram of these volcanic rocks indicates that the Carboniferous volcanic rocks are enriched in large-ion lithophile elements (such as Rb,Ba,Th,Sr) and depleted in high field strength elements (such as P, Ti, Nb, Y, Ta). The distribution of the rare-earth element has been divided into right-inclined distribution pattern, with the enrichment of light REE and the loss of heavy REE, showing that these volcanic rocks in the Baishan Formation were formed in the volcanic arc environment. According to magma eruption cycle from basic to acid and the erupting interval, the Early Carboniferous volcanic activity can be divided into five volcanic eruption cycles. This studying area is located at edge of the active continent during early Carboniferous period, and the intense volcanic eruptions are closely related to the convergence of the Kazakhstan plate.
