On the gold geochemical field in the Danghenanshan mountains

The high and enormous gold geochemical field in the Danghenanshan mountains is originated from both strata aboundant of gold element and known gold deposits,resulting from the incorpporation of the intense eroding of the water in the earth surface and the envioronment with aridity.The variance coefficient of gold element is a sensitive indication for recongnition of available level of metalizatioin of rock-gold built in the high gold content area,and the intensive differentiation is related to regional geological proccess.The alteratioin of clayis of significance of ore-serveying in different scale;K,Al,and Sn are import antindicative elements;and the contour map derived from the sum of binary values of K,Al,Sn,Au,As,and Sb gives more objective prospective areas than others,i.e.the prospective for gold deposits in Hecigou area is more noticeable than in Zazigou area.
