摘要
1999年,都兰县沟里地区开展1∶5万水系沉积物测量,圈出了26处多元素综合异常,其中AS-7、AS-10、AS-17等异常均为矿致异常。AS-23、AS-24、AS-25综合异常位于工作区;2005年崯田物化探公司对这3个多元素综合异常进行了Ⅲ级查证,开展了1∶2.5万沟系岩屑测量,共圈定4个综合异常。其中AS-23异常分解为(Ⅰ、Ⅱ、Ⅲ)3个多元素综合异常,AS-24异常区圈出Ⅳ号多元素综合异常。经2007年普查工作,在Ⅳ号异常内发现了金多金属矿体8条。
In 1999, 26 polyelement synthetic abnormalities were found in the 1/50,000 river system deposit survey carried out in Dulan county ditch area, of which AS -7, AS -10, AS -17 were caused by ore deposit and AS -23, AS- 24, AS- 25 distributed in the work area. In 2005 the field geophysical and geochemical company conducted 1 ： 25,000 ditches rock debris surveys to verify the three integrated abnormalities on 11I level, confirming four synthetic abnormalities. The AS -23 abnormality was decomposed into （ Ⅰ , Ⅱ , Ⅲ ） three polyelement synthetic abnormalities; in area of the AS - 24 abnormalitylV polyelement synthetic abnormality was found. 8 golden polymetallic ore bodies were discovered in the Ⅳpolyelement synthetic abnormality area through the general prospecting work in 2007.
