矿相学鉴定和电子探针分析结果表明，两矿床中的铋矿物以自然铋、辉铋矿为主，其次为碲铋矿、硫铜铋矿、辉铋铅矿等；铋矿物作为主要载金矿物，与自然金紧密共生；包村矿区Bi-Au相关系数为0.69，铋矿物与金矿化关系非常密切。

Using optical microscope, manual artificial heavy concentrate, electron microprobe and scanning electron microscopy, we tested major gold- bearing minerals in Zhaishang deposit. Pyrite and scheelite are the most important gold-bearing minerals. Quartz, limonite, and chalcocite are the secondary gold-bearing minerals. Calcite, siderite, barite and other minerals do not contain any gold.

For a 1116Kg chromitite and a 384Kg mantle peridotite sample, by heavy mineral separation and picking up under a binocular microscope following productions are obtained: the UHP minerals including moissanite and over 1000 diamond grains are discovered firstly from the Kangjinla chromitite orebody Cr-11, which is far more abundant than the Luobusa district; a series of unusual mantle minerals like moissanite and a great deal of diamond grains are discovered firstly from the host rocks of chromitite orebody Cr-11, providing the foundation of discussing the chromitite origin and its relation with the host rocks; besides the UHP minerals like moissanite and diamond, various special mantle minerals are revealed from the chromitite orebody Cr-11 and its host rocks including some native elements, alloys, oxides, sulphides, silicates, carbonates, and tungstates.

2人工重砂发现铬铁矿和地幔橄榄岩中的金刚石等特殊地幔矿物。1116 Kg铬铁矿和384Kg地幔橄榄岩大样经人工重砂分选和双目显微镜下挑选矿物，取得如下成果：首次在康金拉11号铬铁矿体中发现了上千粒金刚石，以及碳硅石等强还原环境的超高压矿物，数量远远超过在罗布莎铬铁矿矿区中发现的金刚石；首次在康金拉11号铬铁矿矿体的近矿围岩中发现了大量金刚石和碳硅石等一批异常地幔矿物，为探讨铬铁矿的成因及与近矿围岩地幔橄榄岩的关系奠定了基础；除挑选出金刚石和碳硅石等超高压矿物，在康金拉11号铬铁矿矿体与围岩地幔橄榄岩中还发现了自然铁球、金属互化物、氧化物、硫化物、硅酸盐等一批异常地幔矿物。

As for sulfur isotopic composition, the general feature of two types deposits is a single peak distribution. All δ〓s values of the ores are near zero. The difference of different deposits lies in that the δ〓s values (1. 8-5. 2‰) of LDT are of small positive value and are similar to that of the metamorphic rocks and dioritic porphyrites in the region while the δ〓s values of SDT are always near zero. Features above suggest that two types of deposits have closely genetic relationship to metamorphic and magmatic rocks.

硫同位素组成上，两类金矿床共同的特征是均具有明显的单峰塔式效应，且δ〓S值均位于0值附近不大的变化范围内；不同的是，近程式金矿的δ〓S平均值均接近于0，与该类金矿具密切成因联系的岩体的δ〓S值也接近于0值，而远程式金矿的δ〓S平均值均为小的正值，变化范围为1.8～5.2‰，区内太古代变质岩及矿区内闪长玢岩脉的全岩δ〓S值位于这一区间内，反映了远程式金矿床其成矿物质不仅来源于重熔岩浆，同时还可能部分来源于变质岩围岩。
