中石炭统黄龙组(原称黄龙灰岩),系1930年由李四光、朱森创名于南京龙潭黄龙山。其岩性:上部为灰白微显红色之纯灰岩,底部为白云岩。总厚近百米。黄龙组在华南分布普遍,层位稳定,岩性变化不大。唯珊瑚化石采集和报道较少。近年来,笔者对所存标本(包括自采和地质队采集的)进行了初步整理和研究,对苏、皖南部地区中石炭统一些珊瑚化石标本进行鉴定和描述。现将其结果报道于后,供大家对比和研究中石
The Carboniferous Huanglong Formation (formerly known as the Huanglong limestone) was established in 1930 by Li Siguang and Zhu Sen in Nanjing Longtan Huanglong Mountain. Its lithology: the upper part of pure reddish-brown limestone, dolomite at the bottom. Total thickness of nearly a hundred meters. The Huanglong Formation is widespread in South China, with stable layers and little change in lithology. Only coral fossils collected and reported less. In recent years, the author conducted preliminary collation and research on the specimens (including collected from the mining and geology teams), and identified and described some coral fossil specimens of the Carboniferous in southern Jiangsu and southern Anhui. Now the results reported later, for everyone to compare and study stone
