鸡冠嘴铜金矿床Ⅰ号矿体群矿体地质特征及赋存规律

The orebody's geological characteristic and occurrence regularity of ore cluster No.1 in Jiguanzui copper-gold deposit

鸡冠嘴铜金矿床属典型的矽卡岩型铜金矿床 ,其Ⅰ号矿体群由Ⅰ0 、Ⅰ1、Ⅰ2 、Ⅰ34个位于不同层位的次级矿体群组成 ,主矿体群Ⅰ2 (包括Ⅰ2 0 1、Ⅰ2 0 2 、Ⅰ2 0 3、Ⅰ2 0 4 、Ⅰ2 0 55个矿体 )中各个矿体其产状、形态各异 ,但都充分体现出了与接触带及顶板大理岩的相应性。顶板大理岩的组分特征及构造形态则是决定是否成矿的重要因素。

Jiguanzui copper gold deposit belongs to typical skarn deposit.Its ore cluster No.1 consists of 4 secondary ore clusters(i.e.Ⅰ 0,Ⅰ 1,Ⅰ 2,Ⅰ 3)at different stratigraphic horizon.Of the 4 secondary ore clusters,the Ⅰ 2 consists of 5 orebodies (i.e.Ⅰ 201 ,Ⅰ 202 ,Ⅰ 203 ,Ⅰ 204 ,Ⅰ 205 )in different occurring state and shape,and yet the 5 oreebodies all have relevance to the contact zone and roof marble.The feature and shape of the composition of roof marble are the decisive factors for mineralizing
