| 摘 要： | 布赫特山地区铁铜矿床位于柴达木盆地北缘欧龙布鲁克陆块东北部，地质条件复杂，成矿条件优越，矿床主要赋存于奥陶系中岩组上部和下部碳酸盐岩组合与华力西期中酸性花岗岩和闪长岩的接触带附近。矿体呈明显的磁异常和磁异常变化，矿区内已发现铁矿（化）体4处，铜矿（化）体2处，矿体的形态、产状及分布严格受矽卡岩带控制，发育矽卡岩化、蛇纹石化、黄铁矿化、硅化、绿泥石化、褐铁矿化、孔雀石化等蚀变类型，其成矿类型为矽卡岩型铁铜矿床。

| Abstract: | The iron-copper deposit of Bucht Mountain is located in the northeastern part of the Olongbuluke Block on the northern margin of the Qaidam Basin，with complex geological conditions and superior metallogenic conditions.The deposit mainly occurs in the upper and lower carbonate rocks of the Ordovician Middle Rock Formation，the assemblage is near the contact zone with the Valissian mid-acid granite and diorite.The ore body shows obvious magnetic anomalies and changes in magnetic anomalies.4 iron ore（chemical） bodies and 2 copper ore（chemical） bodies have been discovered in the mining area.The shape，occurrence and distribution of the ore bodies are strictly controlled by the skarn belt.Developed skarnization，serpentinization，pyrite mineralization，silicification，chloriteization，limonite mineralization，malachite and other alteration types and its metallogenic type is a skarn iron-copper deposit. |
