斑岩型矿床含矿斑岩与非含矿斑岩鉴定特征综述

A Summary of Identification Characteristics of Ore-bearing Porphyry and Non-ore-bearing Porphyry in Porphyry Deposits

作为金属Cu的最主要来源和Mo、Au等金属的重要来源,斑岩型Cu(-Mo,-Au)矿床以其规模大、埋藏浅、矿石品位低但矿化均匀,易采易选的特点,一直是矿床学家们经久不衰的研究课题。本文通过收集国内关于斑岩型矿床的资料,介绍了斑岩型矿床地质特征,总结了斑岩型矿床通过岩体形态、流体包裹体、蚀变分带与叠加、岩石化学和副矿物等方面鉴定含矿斑岩与非含矿斑岩的鉴定特征。

As the main source of metal Cu and the important source of metal Mo and Au,porphyry type Cu(-Mo,-Au)deposit has been a long-standing research topic for ore miners because of its large scale,shallow burial,low ore grade,homogeneous mineralization and easy mining and separation.This paper introduces the geological characteristics of porphyry deposits by collecting domestic data on porphyry deposits,and summarizes the identification characteristics of porphyry deposits by rock mass morphology,fluid inclusions,alteration zoning and superposition,petrochemistry and accessory minerals.
