| 摘 要： | 青海化隆基性-超基性岩带是南祁连山一条重要岩带,其内产出若干基性-超基性岩体。通过对化隆基性-超基性岩带的基本地质特征及化隆群结晶基底的综合研究,结合已有研究成果及其相关其他地质信息,发现该基性-超基性岩带中的岩体都不同程度侵位于化隆群中,并具有相似的地质地球化学特征和成矿地质条件。加之带内几处典型的铜镍成矿表现,可见青海化隆基性-超基性岩带具有较好的铜镍成矿条件与找矿潜力。现有的野外工作及找矿实践亦表明了在巨厚红层覆盖下所发育的基性-超基性岩体表现了重要的铜镍矿化显示,同时提示在化隆基性-超基性岩带还有发现新的同类型岩体和铜镍矿床的潜在条件,其资源潜力较好。 |

| Abstract: | Hualong basic-ultrabasic rocks belt is a great important rock belt in South Qilian mountains, and it develops many basic-ultrabasic intrusions. All the basic-ultrabasic intrusions intrude into Hualong Group, and have similar geological and geochemical characteristics and geological conditions by the com- prehensive research of basic geological characteristics and crystalline basement in Hualong group on the ba- sis of research achievement. Together with several typical copper and nickel formation ore features, there- fore, it suggests that Hualong basic-ultrabasic rocks belt has good metallogenic condition of Ni-Cu and prospecting potentiality. Field work and ore-prospecting practice proved that bearing-ore basic-ultrabasic intrusions under thick red cover have good mineralization, and there are potentials for finding new similar intrusions and Ni-Cu deposits in the Hualong basic-ultrabasic rocks belt, and it will have great resources potentiality. |
