摘要
建德铜矿床是浙江西部多金属成矿带中一个引人瞩目的重要矿床。它产于中石炭统底部伴有火山岩、硅质岩和碧玉岩的白云岩中。整合块状矿体之下有一筒状矿化蚀变带。其成分以Ｃｕ＞Ｚｎ＞Ｐｂ为特征。根据矿床地质、地球化学特征以及近年来研究所获得资料。
The Jiande copper deposit in Zhejiang province was previously considered to be of postmagmatic hydrothermal, skarn altered origin However,the current detailed field and laboratory investigation reveal that it is actually a massive sulfide deposit directly related to Late Paleozonic submarine exhalative sedimentation association with volcanism.The Jiande copper deposit is an important and well known deposit in the metallogenic belt of polymetas in the western Zhejiang.It is typical deposit with Cu>Zn>Pb in composition and occurs at the bottom of middle Carboniferous carbonate rock,associated with volcanic rock,silicalite and jaspilite.The pipe mineralized alteration zone is conformably under the massive ores.Based upon the geological,geochemical characters of the ore deposit and new data obtained in recent years,it is considered that the deposit should be formed in submarine exhalative sedimentary environment.
