摘要
三个井金-多金属矿床位于天山-阴山巨型纬向复杂构造带北山的黄砬子-三个井近EW向挤压带东段,区内地层、构造、岩浆岩、航磁及化探异常发育.目前在矿区内已发现金-多金属矿脉20余条,共提交预测资源量(334):金5801kg、银63009kg、铅45812t、铜2027t,矿床规模达中型以上.该矿床类型属中-低温热液蚀变岩型.通过对三个井金矿区与相邻矿区成矿地质背景、金矿床地质特征和控矿地质条件的分析,对本区金-多金属矿床的空间产出形态、成矿规律及矿床成因有了初步认识,认为黄砬子-三个井多金属矿带是寻找金-多金属热液蚀变岩型矿床的有利地带.
The Sangejing gold-polymetalic deposit is located in the east sect of Huanglizi-Sangejing extrusion strip nearing EW, and the extrusion strip is in the Beishan-locus of supersize latitudinal complex tectonic band from Tianshan to Yingshan,the stratum, structure,magmatic rock, aeromagnetic and geochemical anomalies are developed in the area. Now we have find there is more than twenty vein of gold-polymetalic in the mine, the resource reserves(334) of forecast which is put include: Au 5 801 kg,Ag 63 009 kg, Pb 45812t,Cu 2027t,the size of deposit have reached above medium. The type of deposit is mid-low temperature hot-liquid altered rock. Analysing the ore-forming geological background, geological features of gold deposit, geological conditions of ore-controling, we have a primer knowledge about the space-outputing shape, metallogenic rule and deposit contributing factor in gold-polymetallic deposit this area,we think that polymetallic ore band in Huanglizi-Sangejing is a favourable situation to seek the gold-polymetallic hot liquid altered rock deposit.
