摘要

摘要: 通过对陕西铜矿成果和国土资源大调查工作中新发现铜矿的研究总结,划分出8类铜矿成因类型,其中重要的类型为海相火山气液型、接触交代型、受变质型;划分出与铜矿有关的成矿系列有9个。其中主要与铜矿床(点)有关的成矿系列为、与元古代中—酸性岩有关的铁铜矿床成矿系列,加里东—印支期与中性—酸性花岗岩类有关的铁铜金钨萤石矿床成矿系列,与海相中基性火山岩有关的铜锌矿床成矿系列,前寒武系变质火山岩中的铜锌黄铁矿床成矿系列,海底喷流沉积-热液改造铅锌铜矿床成矿系列;划分出与铜成矿有关的Ⅲ级成矿区(带)有5条,有关的Ⅳ级成矿区(带)有9条,主要铜找矿区(带)(相当于Ⅴ级)有14条,其中铜重点找矿区(带)有:勉县七里沟—宁强巩家河铁铜成矿带,铜峪—西骆峪铜锌成矿带,蟒岭—牧护关燕山期铁铜钼钨铅锌萤石成矿带、小河口—园子街铁铜金成矿区。

Abstract: From researches on the copper ore deposit production of Shaanxi province and the new found copper ore deposits in territorial resources survey, 8 genetic types of copper ore deposits were classified, of which the important types are volcano thermal fluid of marine facies type, contact metasomatism type, and metamorphosed type; and 9 metallogenic series related to the copper ore were classified, of which the metallogenic series mainly related to copper ore deposits (spots) are iron-copper deposit series related to proterowic acid-neutral rock, iron-copper-aurum-wolfram-fluorite deposit series related to Caledonian-Indosinian neutral-acid granite rocks, copper-zinc deposit series related to marine neutral-acid volcanic rock, copper-zinc-chalcopyrite deposit series related to Precambrian metamorphosed volcanic rock, and marine jet flow sedinent-theimal fluid reformed lead-zinc-copper deposit series; and 5 Ⅲ-level and 9 IV-level deposit zones related to copper deposits and 14 main copper prospecting zones (equivalent to V-level) were classified, of which the copper basilica prospecting zones are iron-copper deposit zone in Qiligou of Mianxian-Gongjiahe of Ningqiang, copper-zinc deposit zone in Tongyu-iluo yu,Yanshanian iron-copper-molybdenum-wolfram-lead-zinc-fluorite deposit zone in Mangling-Muhuguan, and iron-copper-gold deposit zone in Xiaohekou-Yuanzijie.
