海侵
- transgression;advance of sea
-
在开裂高峰期或开裂向闭合转换期,海侵体系域与高位体系域优势均不明显,层序结构样式以TH型较多;
During the stage of opening peak or transition from opening to closing , the dominance of the transgression systems tract and highstand systems tract were not obvious and the sequence stratigraphic architecture styles were dominated by the TH style ;

认为烃源岩的富集层段主要位于H型样式的二级层序海侵体系域(TST)中,其中TST的三级层序样式中,T型数量较多或H型数量较少。
It is considered that enrichment of the source rocks is mainly located in TST of Pattern H ( Grade ⅱ transgressive sequence marine domain ), while in Grade ⅲ sequence of TST , the number of Pattern T is more and H is less .
-
区内缺乏低位域,层序由海侵体系域(TST)和高位域(HST)组成,并且海侵体系域不甚发育,高位域组成了层序的主体。
The sequences are only composed of transgressive systems tract ( TST ) and highstand systems tract ( HST ) because of lack of lowstand systems tract ( LST ), and in fact the sequences are mainly composed of HST because of poor development of TST .
