摘要
塔里木盆地西南地区,在区域构造上属西南坳陷。本区虽经多年工作,但上、下第三系的接触关系和乌恰群的时代归属问题,至今未能全面确切地得出结论。本文根据对上、下第三系的区域分布、钻探成果与地震资料的综合研究,结合本人在野外工作中收集到的典型资料,对上述问题进行了讨论,认为上、下第三系的接触关系为角度不整合—微角度不整合(假整合),乌恰群的时代为中新世,而不应是渐新世至中新世。
The Southwest Tarim Basin belongs to Southwest Depression in regional structure. The conact relationship between upper and lower Tertiary and age ownership of Wuqia group, even many years work has been done in this area, have not got fully and exactly conclusion till today.This paper discussed those problems on the basis of regional distribution of upper and lower Tertiary, results of well data and integrated study of seismic data, it also combined the typical data gathered from feild by author and concluded that the contact relationship between upper and lower Tertiary is an angle- unconformity or slight angle-unconformity(pseudo conformity) , the age of Wuqia group belongs to Miocene Epoch (rather than) from Oligocene to Miocene Epoch.
