摘要
盐源西苑坪—模范村喜马拉雅期石英二长斑岩群的发现和肯定对认识该区大陆板内岩浆成矿作用及找矿工作具有特殊意义。浅部验证坑道已获斑岩型细脉浸染状铜矿体。模范村是第一个被确定的斑岩型金银铜矿床，这不仅对四川而且对云南在今后寻找该成矿带同类矿床具有借鉴和指导作用，不久的将来必会有一批同类矿床发现。本文就其构造背景、地质特征及找矿前景作简要论述，并对菁河－程海成矿带的其它斑岩群的找矿前景予以预测。
The discovery of Himalayan beschtauite groups in Xifamping-Mofancun district,Yanyuan is of special significance to continental intraplate magnatic ore-formation and ore prospecfing.A porphyry copper orebody has been discovered.The discovery of Mofancun porphyry An-Ag-Cu deposit is of inportance to ore prospecting in the Jinshajiang-Ailaoshan mefallogenic Belt.This paper outlines its tectonic setting,geological features and ore prospecting perspecfive for the other porphy groups in the Qinghe-Chenghai metallogenic belt.
