铜厂河铜矿产于大陆溢流钙碱性玄武岩中,铜矿化主要产于第三喷发旋回中晚期,即第8喷发层(P3 em3-8)中上部,赋矿岩石主要为杏仁状玄武岩,矿体呈似层状产出,经详查以估算资源量矿石量约115万 t,铜金属量1.1万 t,铜品位0.98%,为一小型铜矿床。通过总结铜矿化特征与矿化规律,对我国西南地区广泛分布的同期玄武岩,特别在黔西北地区具有相似成矿地质背景,对其找矿可提供借鉴。
銅廠河銅礦產于大陸溢流鈣堿性玄武巖中,銅礦化主要產于第三噴髮鏇迴中晚期,即第8噴髮層(P3 em3-8)中上部,賦礦巖石主要為杏仁狀玄武巖,礦體呈似層狀產齣,經詳查以估算資源量礦石量約115萬 t,銅金屬量1.1萬 t,銅品位0.98%,為一小型銅礦床。通過總結銅礦化特徵與礦化規律,對我國西南地區廣汎分佈的同期玄武巖,特彆在黔西北地區具有相似成礦地質揹景,對其找礦可提供藉鑒。

Tongchanghe basalt type copper deposit is located in the continental flood calc alkaline basalt.Cop-per mineralization mainly occurs in the middle and later period of the three eruption cycles,i.e.the middle and upper part of the 8th eruption layer (P3 em3-8 ).Ore bearing rock is mainly as amygdaloidal basalt.The orebody is layered.Through detailed investigation of resource assessment,the ore amount is about 1,150,000 t, copper metal is 1 1,000 t,copper grade is 0.98% in average.The deposit is a small copper deposit.By sum-marizing copper mineralization characteristics and regularity,the paper will provide reference for the copper exploration in the basalt in the southwest of China,especially in the northwest of Guizhou Province.
