安徽铜陵地区铜金矿化关系及其成因初探

铜陵地区是长江中下游成矿带中重要的铜金成矿区之一,区内已发现数十处铜、金矿床,二者间的关系主要表现为:矿床类型有铜矿床、金矿床和铜金(或金铜)矿床,空间上有内铜外金、下铜上金、西铜东金(左铜右金)分布规律,时间上金矿化一般晚于铜矿化.本文从金、铜地球化学性质及成矿过程中物理化学条件的变化对成矿作用的影响等方面初步探讨了二者间存在上述关系的成因,以期对该区及相似地区找矿有所启迪.

STUDY ON RELATION OF COPPER AND GOLD MINERALIZATION AND ITS GENESIS IN TONGLING AREA, ANHUI

Tongling area is an important copper and gold metallogenetic district in the Middle and Lower Reaches of Changjiang River,where many copper and gold deposits have been found The relations of copper and gold deposits in this area are as follows:there are copper deposits,gold deposits and copper gold(or gold copper) deposits;the copper deposits are inner,lower and west located,while the gold deposits are outer,upper and east located;generally,gold mineralization is later than copper mineralization This paper studies geochemical featrues of gold and copper,the affection on mineralization of physical and chemical conditions in the metallogenic progress,and genesis of the relation of gold and copper deposits
