摘要
对西藏自治区北部南羌塘盆地毕洛错地区下侏罗统曲色组石膏岩层进行了研究。根据岩石地层和生物地层资料,确认毕洛错地区的石膏岩层和油页岩为曲色组的一部分,地质时代为早侏罗世,并确认下侏罗统曲色组在区域上可能是寻找油气、油页岩资源的重要层位之一。
We have conducted an intensive study of gypsum rock and dysaerobic fauna in the Early Jurassic Quse Formation in the Biloucuo area of the southern Qiangtang Basin,northern Tibet.In the Biloucuo area,the gypsum rock and the oil shale can be identified as part of the Quse Formation.Its geologic age is Early Jurassic Toarcian.The Early Jurassic Quse Formation represents an important dysoxia event.It should be one of the important horizons for oil and gas exploration in this area.
