从主金属元素组合分带看甲乌拉银多金属矿田的找铜前景

A DISCUSSION ON PROSPECTS FOR COPPER DEPOSITS IN THE VIEW OF THE ASSOCIATIVE ZONING OF MAJOR METALLIC ELEMENTS IN JIAWULA SILVER-POLYMETALLIC ORE FIELD

甲乌拉银多金属矿田是由甲乌拉和查干布拉根两个银多金属矿床组成，为近年来发现和探明的一个大型次火山热液脉状银多金属矿床，部分区段已见铜的工业矿体，本文着重从已知主要矿带（２号矿带）的主金属元素组合分带入手，对该区的找铜前景问题进行初步探讨，并认为找到中型规模的铜矿床是很有希望的。

The Jiawula silver-polymetallic ore field consists of the Jiawula silver-polymetallic deposit and the Chaganbulagen silver-polymetallie deposit, which is a large subvolcanic hydrotliermal vein type silver-polymetallic ore field and was discovered and explored in the late years, the copper ore bodies have also been found at some parts of the field. Through systematic studies on the associative zoning of the major metallic elements of the main ore body (No. 2 ore body), the prospects for copper deposit has been roughly discussed, authors think that it is possible to find a middle scale copper deposit in the field.
