| 摘 要： | 本文从成矿地质背景、成矿时代、成矿物质来源、成矿介质条件和成矿机制等５个方面，论述了河南嵩县祁雨沟及其外围地区斑岩角砾岩型、隐爆角砾岩型、破碎带蚀变岩型和石英脉型金矿。该系列金矿是在燕山中晚期钙碱性花岗质岩浆基础上发育起来的，具有同源、同期、同成因、不同空间成矿的特征，称之为以隐爆角砾岩型为主的金矿床系列。

| Abstract: | Study of five aspects such as geologlcal setting, metallogenic epoch, source of ore-- forming materials, medium condition and mechanics of metallogenlsls appIOves that the porphyry-- breccia type, crypto--explosive breccla type. altered fracturezone type and quartz veitl type of gold deposits developed in the Qiyugou area of the eastern Qlnling fold zolle belong to a metallogenlc series relaied to the mid -- late Yanshania cafe--alkline granitoids. This series is characterized by crypto--explosive brecciatype deposits. |
