前言 石炭系黄龙组下部白云岩在长江中下游地区分布很广,又是该区铁铜矿产的主要控矿层位之一,但其时代归属等问题长期争论未决。本着科学研究面向国民经济建设、面向地质找矿的方针,江苏省古生物学会、江苏省地质学会、安徽省古生物学会于9月16日—25日联合主办了一次“苏浙皖地区黄龙组底部白云岩时代归属问题现场论讨会”。 会前,有关单位做了不少业务准备工作,取得了一些重大进展,将该套白云岩的研究程度提高了一步。
Preface The lower dolomite in the Lower Carboniferous Huanglong Formation is widely distributed in the middle and lower reaches of the Yangtze River and is one of the major ore-controlling layers of iron-copper deposits in the area. However, its age attribution and other issues remain controversial. In line with the principle of scientific research oriented to the national economy and geology prospecting, the Association of Paleontology of Jiangsu Province, Jiangsu Geological Society and Anhui Paleontological Society co-sponsored the “Huanglong Group at the bottom of Jiangsu, Zhejiang and Anhui provinces Dolomite attribution issue on-site seminar. ” Before the meeting, the relevant units have done a lot of business preparatory work and made some significant progress, which has taken the study of the dolomite a step further.
