灰屑岩
Calcarenite silicon-wackestone of the upper and lower silicon members deposit f rom contour current s and occur on the lower of the carbonate slope. 等深流沉积物形成了上、下硅质层段的砂屑硅质粒泥灰岩 ,主要分布于斜坡下部。
The results show that the main rock types in Yingshan formation are micritics, calcarenite and dolomite, of which, micritics and calcarenite have the best development and the widest distribution. 研究区内鹰山组主要岩石类型为泥晶灰岩、砂屑灰岩和白云岩，其中泥晶灰岩、砂屑灰岩发育最好，分布最广；
