| 摘 要： | 西藏南部定日地区上白垩统旧堡组与遮普惹山坡组之间为平行不整合接触.本文详细研究了定日地区各拉木、申克扎两条剖面中旧堡组与遮普惹山坡组地层的岩石和古生物学特征,系统描述了其中产出的浮游有孔虫13属34种.对浮游有孔虫的研究表明:各拉木剖面旧堡组属康尼亚克-三冬期沉积,上覆遮普惹山坡组沉积开始于坎潘晚期,推断其间的平行不整...

| Abstract: | A disconformity was discovered in the late Cretaceous strata between the Jiubao Formation and the overly-ing Zhepure Shanpo Formation in the Tingri area,southern Tibet.In this study,two stratigraphic sections(Gelamu and Shenkeza sections) across the disconformity were measured in detail in the field,and planktonic foraminifera were carefully examined to constrain the age of this disconformity.In total,34 species of 13 genera were identified and des cribed in the present paper.At the Gelamu Section,Dicarinel... |
