巢湖地区早石炭世地层主要出露于无为县山里黄家、白牡山,巢县南部银屏、岱山,巢县北部东风石矿、凤凰山、维尼纶厂,含山县花山、方山及和县香泉镇夹山关等地。这一地区隶属于扬子地层区下扬子地层分区巢县地层小区。区内的下石炭统普遍缺失杜内期(岩关期)早期的沉积,自下而上划分为三组、二段:金陵组、高骊山组、和州组(下段、上段),总厚20.1—57.1米,除高骊山组为滨海—浅海相碎屑岩外,余者主要为浅海相碳酸盐岩建造。
The Early Carboniferous strata in Chaohu are mainly exposed in the mountainous areas of Huangjia, Bajushan and Banxiu in the southern part of Wuhu County, Dongfeng Quarry in the southern part of Chaozhou County, Fenghuangshan Mountain, Vinylon Plant, Huashan County, Fangshan Mountain and He County Xiangquan Town folder Hill and other places. This area belongs to the Lower Yangtze Formation in the Yangtze Formation. The Lower Carboniferous in the area generally lacks sediments in the early stage of Duneng (Yan Guan Period) and is divided into three groups from the bottom up: the Jinling Formation, the Gaosishan Formation and the Hezhou Formation (lower and upper sections) with a total thickness of 20.1 -57.1 meters, except that the Ga Lishan Formation is a coastal-shallow marine clastic rock, with the remaining mainly composed of shallow marine carbonate rocks.
