本文以东海西湖凹陷钻井资料为基础,综合分析了花港组沉积时期构造活动及海泛作用在沉积相发育过程中的控相机制,对该地区长期认定的"再沉积化石"及不同构造单元的控相能力差异重新提出个人看法,并建立了西湖凹陷花港组沉积模式。

According to the drilling data of Xihu Trough, this paper gives a synthetical discussion on the facies-controlling mechanisms of tectonic actions and invasion of the sea in the deposion of Huagang Formation, puts forward some personal views on so-called "reworking fossils" in Huagang Formation, and establishes a depositional mode for Xihu Trough.
