福建地壳各岩类铜元素丰度及铜的矿源层(岩)讨论

Discussion on the Copper Abundance of Different Rocks in theCrust of Fujian Province and on the Copper Source Beds

根据福建省最新岩石测量成果得出的各岩类铜元素丰度，讨论和初步确定了福建铜的矿源层（岩）。提出可按照丰度值高低，铜的初始赋存状态与被解离的难易，有无矿床（点）及具找矿意义的异常产出这3项因素，进一步将矿源层（岩）划分为较可靠的、可能的和潜在的3个级别。

Based on the recent analysis results of copper abundance of different rocks in the crust ofFujian Province, in this paper the author discussed and preliminarily decided the coppersource beds of Fujian Province which can divided into three grades according to the followingthree factors, that is the copper element abundance, the initial occurrence and fractionaldegree of copper elements, and ore deposits (spots) or anomalies available for further orepros poeting.
