| 中文摘要: |
| 大兴安岭南段是我国北方重要的锡铅锌银多金属矿集区,区内成矿地质条件优越,找矿潜力巨大。哈尔楚鲁图铅锌多金属矿床位于内蒙古赤峰市克什克腾旗北部,大兴安岭南段西坡成矿带西南端。在野外调查和室内测试的基础上,通过对该矿床进行基础地质特征和控矿条件研究认为,矿体的赋矿围岩主要为华力西晚期闪长岩,而成矿岩体为燕山期隐伏花岗岩。矿体均受北西向张扭性断层构造控制,而北东向压扭性断裂普遍蚀变,无铅锌矿体,为导矿构造。矿化蚀变类型以绢云母化、硅化、绿泥石化为主,与成矿关系密切,可作为找矿标志。而萤石化、方解石化为矿化后期蚀变,亦可作为间接找矿标志。综合分析认为,该矿床是受断裂构造控制的中—低温热液充填式脉状铅锌多金属矿床。 |
| 英文摘要: |
| The Southern Great Xing’an Range is one of the important metallogenic centralized region of Sn-Pb-Zn-Ag Polymetallic in Northern China. The condition of geological mineralization in the area is outstanding, have good mineral-forming condition and great prospection potential. The Haerchulutu Pb-Zn polymetallic deposit is located in the southwestern end of the West slope Southern Great Xing’an Range, and north of szeketenqi, chifeng city, Inner Mongolia. On the basis of field investigation and indoor testing, through the study of basic geological features and ore control conditions, it is believed that the surrounding rock of the ore body is mainly diorite in late Variscan, while the ore-forming rock body is concealed granite in Yanshanian. The ore bodies are all controlled by the NW tensional fault structure, while the NE compressive and torsional faults generally undergo alteration but no Pb-Zn ore bodies, which is the guide structure. The types of mineralization alteration mainly include sericitization, silicification and chloritization, which are closely related to mineralization and can be used as the prospecting criteria. Fluoritization and calcitization into mineralization later stage, also can be used as indirect prospecting criteria. It is concluded that this deposit is a middle-low temperature hydrothermal Pb-Zn polymetallic deposit controlled by fault structure. |
