| 中文摘要: |
| 河南省卢氏县夜长坪钼矿是近期在东秦岭钼矿带中新发现的大型—超大型斑岩—夕卡岩型钼矿床。该矿床受近东西向和北北东向棋盘格子式断裂构造复合控制,矿体赋存于深部花岗斑岩体内及外接触带夕卡岩中。文章利用矿区采集的代表性极高的花岗斑岩样品进行主量、微量元素测试,经过综合研究分析,推断矿床成矿物质主要源于下地壳,同时混有少量幔源组分；深部花岗斑岩与成矿有关,浅部花岗斑岩与成矿无关,且切穿先前形成的矿体。 |
| 英文摘要: |
| Yechangping Mo deposit, located in Lushi county of Henan province, is a newly discovered large - super-large sized porphyry-skarn type molybdenum deposit in the East Qinling molybdenum belt. This deposit is controlled by the EW-trending and NNE-trending fault, and hosted in the deep granite porphyry and skarn nearby the internal and outlier contact zone; The representative samples were collected from the granite porphyry for the chemical composition analysis of main and trace elements; through the comprehensive analysis and study, the authors predicted that the mineralization sources mainly derived from the deep crust and minor mixed with the component of mantle. The deep granite porphyry is closely associated with the molybdenum mineralization, in the contrast, the granite porphyry outcropped in the upper part has nothing with mineralization which cut through the previous ore body. |
