中文摘要：

祁雨沟金矿位于华北克拉通南缘的熊耳地体，是典型的爆破角砾岩型金矿。本文全面总结并深入分析了祁雨沟金矿的同位素地球化学研究资料，以氢-氧-碳同位素体系确定成矿流体由岩浆热液向大气降水热液演化，以碳-硫-铅同位素体系厘定成矿物质主要来自岩浆流体系统，以铅、碳同位素确定熊耳地体南侧的中-新元古代地层是不可缺少的成岩成矿物质来源之一。因此认为：在中生代华北与扬子板块碰撞造山过程中，熊耳地体南侧的陆壳板片沿马超营断裂俯冲到熊耳地体之下，通过变质脱水-熔融作用派生了祁雨沟岩浆-流体成矿系统，其成因可由碰撞造山成岩成矿与流体作用模式（即CMF模式）解释。

英文摘要：

The Qiyugou gold deposit, Songxian County, Henan Province, is a typical explosive breccia-type gold deposit occurring at the Xiong＇er terrane, southern margin of the North China craton. The isotopic data about this deposit are fully summarized and thoroughly interpreted. As traced by H--O--C isotope systematics, its ore-fluid system evolved from magmatic to meteoric. The C--S--Pb isotope ratios imply that the ore-forming materials were mainly sourced from the magma-fluid system. The carbon and lead isotope ratios still indicate that the Meso Neoptoterozoic sequence south of the Xiong＇er terrane is a necessary source of the ore-forming material. Hence, in this paper we suggest that the Qiyugou magmafluid ore-system was originated from metamorphic devolatilization--melting of the A-type subducted crustal slab beneath the Xiong＇er terrane; and the A-type subduction occurred along the N-dipping Machaoyong fault which is interpreted as the southern boundary of the Xiong＇er terrane, during the Mesozoic collisional orogenesis between the Yangtze and North China continental plates. The genesis and metallogenic process of the Qiyugou deposit can be well interpreted using the tectonic model for collisional orogeny, metallogeny and fluid flow （abbreviated to be CMF model）.
