衢州中生代火山岩地球化学特征与铀成矿关系
Relationship between the geochemical characteristics of Mesozoic volcanic rocks and uranium mineralization in Quzhou
摘要
Abstract
The Daoqiaowu(670)mining area in the north of Quzhou and The Dazhou(660)mining area in the south of Quzhou belong to the volcanic rock-type uranium deposits,which are important uranium mining areas in the eastern part of Ganzhou-Hangzhou uranium mineralization zone,and their metallogenic characteristics have strong representative significance.This paper intends to comprehensively sort out the geochemical data of major elements,trace elements and rare earth elements of Huangjian formation and Jiuliping formation of the main ore-bearing surrounding rocks in Daoqiaowu(670)mining area and Dazhou(660)mining area,and further probe the relationship between uranium mineralization and ore-bearing surrounding rocks(source rock nature and tectonic setting)in the mining area based on previous research.At the same time,the commonness and difference in the volcanic rocks of Huangjian formation and Jiuliping formation in the two mining areas are revealed,which provides geochemical evidence for studying the function of ore-forming surrounding rocks in the uranium mineralization.According to the geochemical characteristics of major elements,trace elements and rare earth elements,it is inferred that Huangjian formation and Jiuliping formation are formed with the same source rock melted partially.The two groups of volcanic rocks belonging to different tectonic units have similar characteristics to form uranium mining areas.This paper considers that the metallogenic material and the diagenetic material come from the same rock.关键词
