THE DISCOVERY OF THE LATE TRIASSIC STRATA AND ITS GEOLOGICAL SIGNIFICANCE IN THE SOUTHWESTERN TARIM BASIN
-
摘要: 本文从岩石、生物地层角度介绍塔西南地区首次发现的晚三叠世地层。上三叠统仅分布在乌恰-库斯拉甫断陷中,它与塔西南前陆盆地分属两个原型盆地,这对于塔西南坳陷构造演化史分析和油气评价将起重要作用。Abstract: The first discovered Late Triassic strata was introduced in terms of its petrological and biostratigraphic characters in the paper.The upper Triassic was only distributed in Wuqia-Kusilapu fault depression,which was belonged to a different protobasin comparing with the southwestern foreland basin.This is important for analysis of structural evolution and evaluation of hydrocarbon potential in the southwes tern Tarim depression.
