本文综合了我国主要的一些斑岩铜矿床成矿溶液包裹体资料,提出了我国一些大中型斑岩铜矿床成矿温度一般有大于300℃、350～250℃、250～150℃三个阶段;成矿普遍有高温沸腾现象;成矿溶液的盐度可分为高盐度(大于36％wt)和低盐度两种类型;成矿压力一般较小(140～200大气压)的认识。结合地质和实验资料,把成矿溶液分为三类,提出了成矿模式。结论是高盐度包裹体和气体包裹体的存在是寻找斑岩铜矿化富集地段的标志之一,也可作为岩体含矿性评价的依据,蒸发晕找矿可作为一个斑岩铜矿找矿勘探工作中钻孔评价和检查剖面测量成果的手段。
In this paper, the main ore-forming fluid inclusions in porphyry copper deposits in China are summarized, and some ore-forming temperatures of some large and medium-sized porphyry copper deposits in our country are generally above 300 ℃, 350 ~ 250 ℃ and 250 ~ 150 ℃ Stage; mineralization generally has high temperature boiling phenomenon; the salinity of ore-forming solution can be divided into two types: high salinity (greater than 36% wt) and low salinity; understanding of formation pressure is generally small (140-200 atmospheres) . According to the geological and experimental data, the ore-forming solutions are divided into three types and the metallogenic model is proposed. The conclusion is that the presence of high-salinity inclusions and gas inclusions is one of the hallmarks of the search for the porphyry copper mineralization enrichment area and also serves as the basis for ore-bearing evaluation of the rock mass. The discovery of evaporites can be used as a porphyry copper Mine exploration and exploration work in the drilling evaluation and inspection results of cross-section measurements means.
