| 摘 要： | 栾川-明港大断裂是华北板块与秦岭造山带的构造分界，其西部栾川一带形成了与花岗岩有关的南泥湖、上房等知名钼矿床。天目山岩体位于栾川-明港大断裂西段，具有富硅、富碱，稀土元素中轻稀土富集、重稀土亏损、3Eu负异常及微量元素（w、Sn、Bi、Mo、Be、Nb）含量高等特点，属利于成矿花岗岩。通过对岩体中钼矿物的研究，指出钼矿化的主要富集区及今后找矿的重点区域。

| Abstract: | The Luanchuan-Minggang major fracture is a tectonic boundary between North China Plate and Qinling orogenic belt, in west of which some famous Mo deposits like Nannihu and Shangfang relating to granite have been formed. Tianmushan rockbodies located in west section of the Luanchuan-Minggang major fracture and has characteristics including containing rich Si and alkali, LREE enriched while HREE depleted, negative anomalies of ~Eu and high content of trace elements （W, Sn, Bi, Mo, Be, Nb）, which indicate the rockbodies belong to granites that are favorable for ores forming. The main enriching areas for Mo mineralization with prospecting key areas have been put forward by researching Mo minerals in rockbodies. |
