| 摘 要： | 本文通过对西藏邦铺钼铜多金属矿床成矿元素的沉淀、迁移机制进行了探讨。研究结果表明：HMoO4-、Cu(H2S)(HS)2-是钼铜在热液中的主要存在形式。受温度、压力降低、pH值增大、两种流体混合机流体沸腾等多种因素的影响，导致成矿流体中成矿元素Mo、Cu的络合物的溶解度降低，并伴随围岩蚀变，硫化物按相应的条件沉淀在相应的蚀变带中，从而形成了矿床如今的类型和规模。本次研究也为进一步的找矿提供了指示和方向。

| Abstract: | In this paper,we discussed the migration and precipitation mechanism of the ore -forming elements from Bangpu polymetallic deposit,Tibet.We found that, in hydrotherm fluid,the leading complex compounds of molybdenum and copper are HMoO4- and Cu(H2S)(HS)2-.It is the decline of temperature and pressure ,the increase of pH value , two kinds of fluid mixing and fluid boling that reduced the solubility of Mo,Cu complexes in the ore-forming fluid,and accompanied wall rock alteration,Mo,Cu sulfide precipitated in the corresponding alteration zone,which formed the type and scale of this deposit now.Meanwhile,this study also provides an indication of further prospecting and direction. |
