据1983年西北有色地勘公司物探队资料,小秦岭地区熊耳群地层中金丰度值为150PPb。陕西省地矿局第六地质队在小秦岭地区做了11幅的1:5万水系沉积物测量,金的析出限1 PPb,各图幅均有大片背景含量来析出。在洛源地区用10PPb圈出Au异常。东鳞河南省在小秦岭做了大量岩石微金测试,王亨治获小秦岭一带太古代太华群126样
According to the 1983 Northwest Non-ferrous Geological Prospecting Company Geophysical Team data, small gold Qinling ear Aurora formation gold abundance value of 150PPb. The Sixth Geological Team of Shaanxi Provincial Bureau of Geology and Mineral Resources made 11 samples of 1: 50000 sediments in the Xiaoqinling Mountains. The precipitation limit of gold was 1 PPb, and all the maps had large background content to precipitate. In the Luoyuan area with 10PPb loop Au anomaly. Dongling Henan Province in the small Qinling Mountains done a lot of rock micro-gold test, Wang Hengzhi was too small Qinling Archean Pacific Group 126
