中文摘要：

阳山金矿床位于西秦岭勉略缝合带内，是我国近期发现的世界级超大型金矿床。本文根据前人稳定同位素和流体包裹体地球化学以及年代学研究，结合矿区构造地质背景和矿物组合，讨论其成因机制。研究表明，阳山金矿床的形成时间与勉略缝合带碰撞期（晚三叠世-早侏罗世）的构造-岩浆事件接近。碰撞造山作用是大规模花岗岩浆活动的主要诱囡。大量变质流体在岩浆热驱动下，沿花岗斑岩与破碎千枚岩的接触带上涌，萃取地层中已相对富集的金，并以络合物的形式搬运成矿。阳山超大型金矿床兼有卡林型金矿和造山型金矿的特征，又有与两者明显区别的地质和地球化学特征，在西秦岭地区的金矿床中具有重要的代表性。

英文摘要：

Yangshan gold deposit, a worldwide super-large gold deposit discovered recently in China, locates in Mianlue suture of the west Qinling. Based on the previous geochemical studies of stable isotopes and fluid inclusions, and combined with information of the tectonic background and the mineral combination types, this article discussed the cause of formation of Yangshan gold deposit. The formation time of Yangshan gold deposit is close to the teetonic-magma event, which happened during collision of Mianlue suture （late Trias to early Jurassic）. A large-scale granitic magma event was generated by the collision and orogeny processes, abundant of magma hydrotherm driven by magma heat streamed up along the aureole of granitic porphyry and fractural phyllite, and extracted the relatively gold-enriched stratum, and then gold was carried around as complex to form gold deposit. Yangshan gold deposit has some characteristics similar to both the Carlin-type and the orogeny-type gold deposits, and is still significantly different from their geological and geochemical features. Yangshan gold deposit is an important typical gold deposit in the west Qinling China.
