东海西湖凹陷苏堤区带花港组沉积相分析

Sedimentary Facies of Huagang Formation of Sudi Division in Xihu Trough, the East China Sea

以东海西湖凹陷苏堤区带钻井资料为基础,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,对该地区长期认定地“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,并建立了西湖凹陷苏堤地区花港组沉积模式。

according to the drilling data of Sudi Division of Xihu Trough,this paper gives a synthetical discussion of the facies-controlling mechanisms of tectonic actions and transgressions in the deposition of Huagang Formation,puts forward some personal views on so-called 'reworking fossils' in Huagang Formation, and establishes a sedimentary mode for southern Xihu Trough.
