Abstract

Abstract:

It is very difficult to find concealed deposits in Qinghai-Tibet plateau permafrost zone,prospecting breakthrough is not achieved using conventional geophysical and geochemical techniques.By carring out concealed ore prospecting forecasting in Zhajiatongna gold ore field in extremely friged zones using soil ionic conductivity and geo-electro-chemical extraction method,we delineate three prospecting target in unknown area.The abnormal scale of No.Ⅰ prospecting target located in the middle of survey area is large and has good ore-forming conditions, should be the key exploration area in future work.Choosing No.4 exploration line as the known profile to theck method effectiveness and feasibility,the results show that there are obvious soil ionic conductivity anomaly and geo-electro-chemical extraction Au element anomalies,this further confirm that the prospecting application effective of these two kinds of methods in Qinghai-Tibet plateau permafrost zone are obvious,so it should be widely applied.

Key words: Soil ionic conductivity, Geo-electrochemical method, Concealed gold deposit, Permafrost Region of Qinghai-Tibet Plateau
