重庆东北城口地区黑色岩系地球化学异常模式
A Geochemical Anomaly Model for Black Shales in Chengkou Region of Northeast Chongqing
摘要
Abstract
Good prospecting effect is gained by stream sediment survey in black shales area in Chengkou region of Northeast Chongqing, which consists of Upper Sinian to Lower Cambrian rocks such as black carbonaceous aleurolite, carbonaceous silty slate, and carbonaceous siliceous rocks. Focusing on the study of black shales and based on comprehensive analysis, this paper has pointed out that manganese, vanadium, silver, and barium are the main ore-forming elements, while manganese mainly enriches in Dengying and Doushantuo formations, vanadium and silver in Lujiaping Formation, and barium in Bashan Formation. The paper has also established a geochemical anomaly model for black shales and shown a clear direction for prospecting.关键词
