| 摘 要： | 粤东地区广泛出露上白垩统叶塘组,根据其露头剖面岩性、岩相和古生物地层学特征判断其为盐湖相沉积.沉积组合与在潮汕坳陷海域钻井LF35-1-1揭示的上白垩统沉积可以进行对比,它们都属于干旱炎热环境下形成的含膏盐沉积岩系,主体岩性均为泥岩、粉砂岩及砂岩,泥岩与粉砂岩夹薄层膏盐岩或砂岩中发育石膏联晶.潮汕坳陷为中国海域中生代盆地油气勘探的有利区域,坳陷具有良好的石油地质条件.粤东中生界盐湖沉积具有与潮汕坳陷相似的沉积背景,岩性、岩相的相似为海域与陆上露头区沉积对比奠定了基础,对比研究有利于初步解决海域油气勘探过程中钻井揭示的有限性,其研究成果对南海北部海域含膏盐岩地层的油气勘探具有重要的意义.

| Abstract: | Yetang Formation of the Upper Cretaceous outcropped widely in the eastern Guangdong Province.It is the salt lake sediment determined with lithology,lithofacies and paleontology-stratigraphy characteristics of the outcrop.This set of sediments can be correlated to the sediments of the upper Cretaceous in well LF35-1-1 in the Chaoshan depression.Both were sedimentary series containing gypsum which formed in the dry-hot environment.Main lithology of both sets of sediments are mudstone,siltstone and sandstone,m... |
