贵州东部黑色岩系中钒矿层地球化学特征及意义
Geochemical characteristics and significance of V deposits in black rock series in east Guizhou province
摘要
Abstract
This paper deals with sedimentary environment and ore-forming process of V deposits in black rock series in east Guizhou province.Samples are collected systematically from shale of hanging wall and foot wall of V ore layers and analyzed REE and trace elements with inductively coupled plasma mass spec-trometry.The result shows that the V-polymettal-bearing beds are deposited under anxic reducing enbi-ronment and V ore bed is formed during rising of sea level under influence of hot water.The V minerali-zation is over printed on normal diagnenesis and is closely related to sub-marine hydrothermal activity and depth of the sea water.V ore bed is very similar to the shale of hanging and foot walls in respect of ele-ment migration and redistribution etc.during diagenesis,epegenesis and even supergenesis.关键词
