贵州—湖南黑色岩系的有机碳和有机硫特征及成因意义

GENESIS AND ORGANIC CARBON/SULPHUR CHARACTERISTICS OF THE LOWER CAMBRIAN BLACK SHALE SERIES IN GUIZHOU-HUNAN

黑色岩系是多种元素的富集体,其中常产出许多大型超大型矿床,越来越受到国内外地学界的重视。然而,关于黑色岩系的成因一直是有争议的问题。对贵州—湖南地区下寒武统黑色岩系有机碳和有机硫的研究,表明黑色岩系的有机碳和有机硫含量较高,因而本文认为黑色岩系形成于低能、缺氧还原的浅水台地边缘环境。

Black shale na, composed of elements.

This paper ale series were relatively higher based on a study of the organic carbon and sulphur of the Lower Cambrian black shale series in Guizhou-Hunan pro an environment of detained, vinces, and demonstrated that the black shale series deposited in reducing and low-energy epicontinental sea.
