小秦岭的含金石英脉在明朝中期已开采利用。我队的找金勘探工作从1965年开始,到1970年结束。为取得更大的成绩,现在又开始工作。现将以往工作收集的资料加以整理,供参考。由于水平低,资料不全,问题难免,望批评指正。一、区域地质小秦岭含金石英脉分布在太古代太华群结晶岩系中。该群由石英岩、富英黑云斜长片麻岩、黑云斜长片麻岩、黑云角闪斜长片麻岩、角闪斜长片麻岩及大理岩等组成。由 Small Qinling gold-bearing quartz vein in the mid-Ming Dynasty has been exploited. Our team’s gold prospecting efforts began in 1965 and ended in 1970. In order to achieve even greater results, we are now back to work. The information collected in the past work is collated for reference. Due to low level, incomplete information, the problem is inevitable, hope to criticism and correction. First, the regional geological Qinling gold-bearing quartz vein distribution in the Pacific Archean crystalline group of rocks. The group is composed of quartzite, feldspar plagiogneiss, biotite plagioclase gneiss, biotite hornblende gneiss, hornblende gneiss and marble. by
