摘要:

汤丹铜矿床位于扬子地块西缘的康滇构造带,矿体产于中元古界落雪组白云岩与黑山组碳质板岩中,分别称为东川式和桃园式铜矿体。铜矿体呈层状、似层状,受层位控制明显,具有多层位赋矿特征。通过梳理主要控矿要素,总结成矿规律,结果表明:汤丹铜矿床的东川式(Ⅰ号和Ⅱ号矿体)与桃园式(Ⅳ号矿体)铜矿体受连通性较好的横向断裂控制,铜矿化强烈的地段,NW向横向断裂较发育; 落雪组渗透性较好的砂质白云岩和黑山组碳质板岩为主要含矿层,岩性控矿特征明显; 赋矿围岩的V/Cr、V/(V+Ni)、Ce/La沉积环境判别图解显示氧化-还原界面是成矿有利地段。结合近两年对东川矿田的深边部找矿工作部分成果,以多层位成矿体系为依据,以因民铜矿区为例进行多层位找矿分析。调查发现因民铜矿区横向断裂较发育,每400 m约有12条,局部分布较密集(每100 m约有9条),落雪组二段青灰色白云岩和黑山组碳质板岩中均具有一定的铜矿化,多个原生晕样品Cu质量分数大于2 000×10^-6,预测在东川式层状铜矿体上部层位具有寻找东川式层控脉状铜矿体和桃园式铜矿体的潜力。

Abstract:

Tangdan copper deposit is located in Kangdian tectonic belt of the western Yangtze Block. The Dongchuan-type and Taoyuan-type copper ore bodies are distributed in dolomite of Mesoproterozoic Luoxue Formation and carbonaceous slate of Mesoproterozoic Heishan Formation, which are stratiform and quasi-stratiform, and controlled obviously by lithology with multi-layer ore-bearing characteristics. Through combing the controlling factors, the metallogenic regularity was summarized. The results show that Dongchuan-type(Ⅰ^# and Ⅱ^#)and Taoyuan-type(Ⅳ^#)copper ore bodies are controlled by transverse fractures with good connectivity. In copper mineralization strong area, NW-trending transverse fractures well develop. The sand dolomite of Luoxue Formation with good permeability and the carbonaceous slate of Heishan Formation are the main ore-bearing layer, and have obvious characteristics of lithologic control orebody. According to sedimentary environment identified by the ratios of V/Cr, V/(V+Ni)and Ce/La of surrounding rocks, the oxidation-reduction interface is favorable area for mineralization. Combined with the prospecting results of Dongchuan ore field in recent years, based on the multi-layered metallogenic system, taking Yinmin copper mine as an example, the multi-layer prospecting was analyzed. It is found that the transverse fractures well develop in Yinmin copper mine with about 12 pieces per 400 m, and part is relatively dense with about 9 pieces per 100 m. Copper mineralization exists in cinerous dolomite of the second member of Luoxue Formation and carbonaceous slate of Heishan Formation. The contents of Cu in several primary halo samples are more than 2 000×10^-6. It can be predicted that the upper layer of Dongchuan-type stratified copper ore body has the potential to search for Dongchuan-type stratabound vein copper ore body and Taoyuan-type copper ore body.
