| 中文摘要: |
| 甘肃北祁连西段桦树沟铁铜矿床是西北地区一个非常重要的铁铜矿床，对其地质特征及成矿模式的研究，将会对研究该成矿带铁铜矿床的成矿模式具有深远意义。通过大量的工作，认为桦树沟铁铜矿床为产于长城系上岩组的一套陆源碎屑岩夹碳酸沉积建造的同生海底喷流沉积矿床。铁矿体控矿构造主要是区域褶皱带，主要赋存于长城系上岩组的含铁细碎屑—粘土岩建造中，具体岩性为千枚岩。铜矿体的产出明显受后期韧性剪切带和层间滑动带共同控制，主要矿石类型有含铁碧玉岩型和蚀变千枚岩型两种。 |
| 英文摘要: |
| The Huashugou Fe-Cu deposit in the western section of the North Qilian Mountains, Gansu Province, is a very important Fe-Cu deposit in the northwest of China. A great deal of work suggests that this deposit a set of continental clastic rocks intercalated with carbonate sedimentary formation of syngenetic submarine exhalative sedimentary deposits occurring in the upper strata of the Great Wall System. The ore-controlling structures of iron-ore bodies are mainly regional fold belts, which occur mostly in the iron-bearing fine clastic-clay rock formation of the Upper Changcheng Formation, consisting of phyllite. The occurrence of copper ore bodies is obviously controlled by ductile shear zones and interlayer sliding zones in the later period. The main ore types include iron Jasper and altered phyllite. |
