摘 要: 研究區(qū)位于河南省西部，大地構(gòu)造位置位于華北陸塊南緣，屬于小秦嶺-崤山-熊耳山金銀多金屬成礦帶。出露基底巖性為太華群變質(zhì)巖，蓋層為熊耳群火山巖，巖漿巖以花崗巖類為主。通過(guò)對(duì)典型礦床C-H-O-S-Pb同位素和流體包裹體研究，以及對(duì)區(qū)內(nèi)金銀多金屬礦的成礦地質(zhì)背景、成礦物質(zhì)來(lái)源及控礦規(guī)律的綜合分析，建立了研究區(qū)成礦模式。研究結(jié)果表明：熊耳山礦集區(qū)金銀多金屬礦成礦流體和成礦物質(zhì)具有殼幔混合特征，主要來(lái)源于地幔；成礦階段分為石英-黃鐵礦階段(I)、石英-多金屬硫化物階段(Ⅱ)及石英-碳酸鹽階段(Ⅲ)；熊耳山礦集區(qū)成礦高峰期集中在220 Ma-140 Ma-120 Ma等3個(gè)時(shí)間段，成礦時(shí)代以燕山期為主，其次為印支期。

Abstract:The study area is located in the west of Henan Province, tectonically located in the southern margin of North China block, belonging to Xiaoqinling-Xiaoshan-Xiong’ershan Au-Ag polymetallic metallogenic belt. The exposed basement lithology is metamorphic rocks of Taihua Group, and the cover is the Xiong''''er Group volcano rock. The main magmatic rock is granite. Through the research on C-H-O-S-Pb isotope and fluid inclusion, and comprehensive analysis on the metallogenic geological background, metallogenic material source and ore controlling regularity of Au-Ag polymetallic deposits in this area, the metallogenic model of the study area is established. The results show that the ore-forming fluids and ore-forming materials, with crust mantle mixing characteristics, mainly derived from the mantle; the metallogenic process is divided into quartz-pyrite stage (I), quartz-polymetallic sulfide stage (II) and quartz-carbonate stage (III); the peak period of mineralization is concentrated in 220 Ma-140 Ma-120 Ma, and the metallogenic epoch is mainly in Yanshan period, followed by Indosinian.
