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。

Ore deposit, have been studied detailly; the orebody pattern (sedimental bedded ores combined with stringer ores of hydrothermal origin) is also outlined; four metallogenic epoches are devided; the zoning of mineralization (including zones of ores, elements, mineral assemblages and temperature of mineralization) have been depicted; the main types of wall-rock alteration are characterized as propylitization of basic rocks and pyritization-sericitization-silicification of acidic pyroclastic rocks; the origin of ores and seven kinds of main minerals have been studied; and the metamorphism and deformation of orebodies is thought mainly due to the shearing and the intrusion of subvolcanic rocks

研究了七个矿化带特别是I号矿床的矿床地质特征，描绘了矿体的双层结构(沉积矿石与热液充填交代的细网脉状矿石)，划分了四个成矿期次，区分了矿化分带(包括矿石组构的成因分带、元素分带、矿物组合分带、温度分带)，指出了围岩蚀变的主要特征是细碧岩青盘岩化而石英角斑质凝灰岩黄铁绢英岩化；对矿石及七种主要矿石矿物的成因作了研究；探讨了矿体的变质、变形，指出韧性剪切及次火山岩侵入的热力作用和应力作用是导致矿体变质变形的主要原因

The results show that thermoluminescent anomalies, whose two edges are higher and the middle is lower, indicate the uranium deposit, the rapidity step of natural voltage indicates the transitive section of oxidation-reduction.

通过室内和野外实测，结果表明土壤天然热释光异常曲线矿体边缘高值，矿体上方低值异常的曲线特征反映了铀矿化存在的可能；中间低值段越宽，起伏变化越小，矿化相对较好；低值段宽，但起伏变化相对较大，则矿体连续性变差；中间低值段狭窄，反映了矿化较差或没有矿化。

准确估计矿体品位的空间分布特征，合理构建矿体形态模型是影响矿体设计和开采的一个重要问题。

The breccias generated due to structure and salt dissolution,which being simplex composition,composed of bituminous limestone and crystalline limestone, intermixing by big and small breccias(n mm～nX10m),no separation.

石膏、天青石等盐类矿体位于似层状砂岩型矿体之下，居蘑菇的中下部位，暗示金顶矿区的矿体分布与底辟构造中的盐丘紧密相关。

From the upper part of the ore body to the rear part, [w(Na2O×w]/[w(K2O)×w] decreases regularly. The element association in the hanging wall is obviously different from that in the lying wall: the hanging wall is enriched with siderophile elements, while the lying wall has abundant thiophile elements.

多元素累乘比值[w(Na2O)×w]/[w(K2O)×w]从矿上向尾部具有规律的下降，矿体上、下盘的元素组合明显不同，矿体上盘富集亲铁元素，矿体下盘富集亲硫元素。

Along with the increasing distance from the main ore-controlling structures, or from the deeper to shallow parts of an ore body, the species and content of metallic sulphides seem to increase.

随远离主干断裂或由矿体的深部到浅部，金属硫化物的种类和含量呈升高的趋势，往往由少硫化物蚀变岩型向多金属硫化物石英脉型转化，矿脉中的上部矿体或同一矿体的上部，金属硫化物的种类和含量较高，这种变化规律和矿脉的地球化学特点是吻合的。
