秋树湾铜矿不仅是河南省仅有的一个规模较大的铜矿床,就是在东秦岭地区亦是为数不多的铜矿床。该矿床以往被作为矽卡岩铜矿进行了勘探。一九七七年笔者曾在该矿区作过研究工作,认为秋树湾铜矿是一个典型的斑岩型矿床,所谓“北山构造角砾岩”则是一个典型的爆发角砾岩筒。现据我们的成果和陆续收到的测试数据,并参考其它有关资料,将其基本特征总结出来,就教于各位专家和同行,不妥之处,请斧正。 The Qiuhuwan Copper Mine is not only the only large-scale copper deposit in Henan Province, but also one of the few copper deposits in the East Qinling Mountains. The deposit was previously explored as a skarn copper mine. In 1977, the author once made research work in this mining area and thought that Qiu Shui Wan copper deposit is a typical porphyry deposit. The so-called “Beishan structural breccia” is a typical outburst breccia tube. According to our results and the test data received one after another, and with reference to other relevant information, we can summarize their basic characteristics and teach them to experts and colleagues.
