Abstract

Middle Jurassic Toutunhe Formation is the main exploration layer in eastern Fukang slope in Junggar Basin. It is significant to search provenance of reservoir sandbodies for oil and gas exploration and development. This paper systematically analyzed clastic components, type and combination characteristic of heavy minerals, clay minerals partition, sandbody distribution and palaeogeomorphology characteristics, and suggested that middle Jurassic Toutunhe Formation in eastern Fukang slope is a multi-source area deposition. During the sedimentary period of Toutunhe Formation, the north-east and southwest direction provenance both exist. The main sources are volcanic rock area at north-east and the middle to high-grade metamorphic rock area at south, the supply of the provenance from the northeast gradually weakened, and the supply from the south gradually increased, and the Beisantai might provide a small part of provenance.
