| 摘 要： | 普朗斑岩铜矿床是近年来发现的一个重要印支期铜矿床.含矿岩体为普朗复式斑岩体,由全岩铜矿化的石英二长斑岩、石英闪长玢岩及花岗闪长斑岩组成,其中矿化较好者主要与石英二长斑岩关系密切.矿区蚀变矿物有伊利石、镁绿泥石、多水高岭石、硬石膏、蒙脱石、黑云母、铁镁绿泥石、白云母、阳起石、金云母、方解石等,蚀变类型主要有钾长石化、黑云母化、钠长石化、硅化、绢云母化、钠黝帘石化、泥化.并且由中心向外依次为硅化核—硅化钾化带—绢英岩化带—青磐岩化带—角岩化带的面型蚀变特征.其中硅化钾化、绢英岩化蚀变带与铜矿关系密切.

| Abstract: | Pulang porphyry Cu deposit is an important Indosinian Cu deposit discovered in recent years. Pulang composite porphyry body is the ore-bearing rock body. It is composed of quartz monzonite porphyry, quartz diorite porphyrite and granite diorite porphyry with whole rock Cu metallogenesis. The rock with good metallogenesis is related close to the quartz monzonite porphyry. There are alteration minerals illite, amesite, halloysite, an- hydrite, montmorillonite, biotite, dumasite, muscovite, actinolite, flogopite, calcite, etc, in the orefield. The main alteration types are polash feldspar alteration, biotitization, albitization, silicification, sericitization, saussuritization, clay grouting. And there are the areal feature of silieifieation core-silicification potassium altera- tion zone-sericitolitization zone-propylitization-hornfelsed zone outwards from centre. The silicifieation potassium alteration, sericitolitization zone are related close to Cu deposit. |
