| 摘 要： | 祁门东源岩体产于城安-大历山岩体的南侧，呈岩株状产出，相伴出露有东源、西源、江家三个岩体。从东源岩体含矿性和地质特征分析，认为东源岩体为含钨地质体，通过含矿热的运移和交代作用，在岩体顶部形成钨矿化的集中区，构成斑岩型钨矿床。从区域岩浆活动看，燕山早期为皖南的主要钨成矿期，具有相似地质背景的绩溪、旌德、宁国地区是具有寻找钨矿的有利地区。

| Abstract: | The Dongyuan intrusion, Qimen occurs to the south of the Chengan-Dalishan intrusion as stocks outcropping separately in Dongyuan, Xiyuan and Jiangjia. Judging from ore-bearing potential and geological features, the Dongyuan intrusion is thought to be a tungsten-bearing geological body. With hydrothermal transport and replacement, tungsten mineralization took place substantially at the top of the rock body to form the porphyry tungsten deposit. In view of regional magmatic activities, early Yanshanian period is the major metallogenic stage for tungsten mineralization in south Anhui, where other favorable places for tungsten exploration are logical settings compared with Dongyuan.
