| 中文摘要: |
| 云南大姚BJQ铜矿位于滇中中生代红色盆地中北部。赋矿围岩为中生代白垩纪的一套陆相碎屑岩。该矿床属于典型的沉积热液改造型矿床。产出矿石矿物有黄铜矿、斑铜矿、辉铜矿、孔雀石、蓝铜矿及大量铁的氧化物,呈块状或浸染状。文章通过对大姚地区地质背景资料的分析,结合该矿区铜多金属元素的地球化学异常特征,圈定有利的找矿靶区。 |
| 英文摘要: |
| The BJQ copper deposit, located in the north-central part of the Mesozoic Red basin in central Yunnan, belongs to the Dayao copper mining area, a sandy type copper deposit. The host rock consist of a set of continental clastic rock of Cretaceous age. This copper deposit is a typical sedimentary hydrothermal transformation type copper deposit. The ore minerals include chalcopyrite, bornite, chalcocite, malachite, azurite and iron oxide in forms of massive and disseminated type. Through the integrated data analysis of geological background in the Dayao copper deposit area, in combination of geochemical anomaly characteristics of copper-multi elements, the prospecting targets were outlined for the next step exploration. |
