金刚石原生矿主要产于金伯利岩和钾镁煌斑岩中。金伯利岩的矿物组成具体涵盖了橄榄石、金云母、钛铁矿、镁铝榴石、磷灰石、铬铁矿、碳硅石等。次生交代矿物具体涵盖了磁铁矿、绿泥石、蛇纹石、方解石等。金刚石是世界上较为珍贵的矿种,当前的数量较少,是国家重点关注的天然矿物。文章主要以新疆皮亚曼背斜南翼金刚石原生矿为例,对成矿地质条件进行了分析,指出了具体的找矿方向。
Primary diamond ore is mainly produced in kimberlite and auriferous porphyry. The mineral composition of kimberlite specifically covers olivine, phlogopite, ilmenite, guassolite, apatite, chromite, and carbon and silica. Secondary replacement minerals specifically covered magnetite, chlorite, serpentine, calcite and so on. Diamond is the world’s more precious minerals, the current small number of natural minerals is the focus of national attention. In this paper, we mainly take the primary wing of the southern wing of the Piyaman anticline in Xinjiang as an example to analyze the geological conditions of the ore-forming and point out the specific prospecting direction.
