Abstract:

白音查干银多金属矿化区是近两年来在内蒙古中东部找到的一处大型构造_蚀变岩型银_铅_锌矿预查区,大规模找矿勘查和综合性研究工作正在进行中。野外地质调查和钻(坑)探结果表明,在白音查干地区及外围存在有数条长千余米、宽几十米到百余米的银多金属矿化带。钻孔中所见矿化体以厚度大、连续性好和品位高为特征,银含量变化范围为(22.4~2270)×10-6,平均值为502.68×10-6;最高值为3775×10-6;铅为0.46%~5.40%,平均值为0.69%,最高值为6.19%;锌1.34%~18.5%,平均值为2.64%,最高值为32.11%。综合性研究结果表明,海西期中酸性岩浆活动为矿化带的形成提供了动力和物质来源,北北西向构造破碎带为成矿物质的堆积提供了空间条件,二叠系泥质粉砂岩为成矿流体的沉淀起到了圈闭作用。根椐上述成矿理论,结合地质和物化探资料数据,认为在白音查干银多金属矿化区及外围实现更大的找矿突破是完全有可能的。
