摘要
利用碎屑岩岩性和骨架颗粒成分、重矿物组合、地震属性和地层倾角厘定了春光区块沙湾组物源体系。研究表明沙湾组物源为扎伊尔山,有西北部、西部和东北部3个碎屑物供给口,春光区块中部是混合物源区,并确定了各个物源体系的波及范围。
By studying the lithologic characteristics of clastic rock, framework grains, combination of heavy minerals, seismic attribution and formation dip angles, the provenance system of Shawan formation of Chunguang block in the western margin of Junggar basin has been determined. The research results indicate Zaire Mountain is the source for Shawan formation and there are three directions for providing clastics: northwest, west and northeast. The middle part of Chunguang block is a mixed provenance area and the extension of various provenance systems has been determined through this study.
