摘要
斑岩型铜矿是当前重要的找铜矿类型之一。８０年代以来，我国斑岩型铜矿找矿进展不大，是因为我国斑岩型铜矿品位较贫，制约着找矿研究和开发。斑岩型富铜矿的找矿，主要应研究斑岩型铜矿与其它类型铜矿床构成成矿系列的主导因素，区域成矿物质来源，多期岩浆成矿作用，多种富集成矿作用等；研究影响斑岩型铜矿氧化带次生富集带发育的因素等，并指出青海南部玉树—扎多—乌丽一带是我国寻找斑岩型富铜矿的最有利地区。
The porphyry
copper deposit presently is an important type of copper deposit.The reason of being less
developed for prospecting porphyry copper deposits in china is that such type of deposits are
of poor grade.It is believed in this paper that prospecting such type of deposits should be
based on studying main factors of ore-forming of porphyry copper deposits and other kinds of
copper deposits,resource of metallogenic elements in the mineral area,multiple magmatic
mineralization,various enriched mineralization,and the factors which affect the development of
secondary enrichment zone of porphyry copper deposits' oxidized zone.Besides,It is pointed
out that the belt of Yushu-Zaduo-Naoliin south Qinghai province is the favourable district of
prospecting enriched porphyry copper deposits.
