Abstract: GOLD Chuang leaf alteration occurs in quartz schist clouds Qinling Group shicao groove rock group, with control by the crushed ore, Au background element showed a normal distribution strong differentiation, Ag, As, Hg , Cr distribution was strongly differentiation. Plane contour feature △ T beaded exhibit positive anomaly NW, forming a strip NW exception. The author discusses the characteristics of body occurrence of gold leaf village, through a combination of methods of geological, geophysical and geochemical etc., obtained ore bodies in this area is a low-temperature hydrothermal alteration type semi-concealed ore body. Chuang gold leaf found in the body, pointed out the direction for the next gold prospecting River Gorge group formation.

Abstract: Yejiazhuang gold mine body was deposited in the erosion of white cloud quartz rock in the Qinling group stone groove trench rock group, the ore body was controlled by the fracture dismemberment zone, the Au element was very strong in the normal background, Ag, As, Hg, Cr was strongly distributed. The characteristics of the T-plane contour show the beaded positive magnetic anomaly of the north-west direction, forming the north-west-to-north band anomaly. The author discusses the characteristics of the deposit of yejiazhuang gold mine, and through the comprehensive application of geological and physical exploration methods, it is concluded that the gold body in this area is a low-temperature hydrothermal erosion variant semi-hidden mineral body. The discovery of the Yejiazhuang gold mine points out the next direction for the prospecting of gold in the formation of the Gorges River.

Abstract: the yejiazhuang gold deposit occurs in the altered dolomite quartz schist of the shigougou formation of the Qinling group. The ore body is controlled by the fracture zone. The Au element is highly differentiated in the normal background, and the Ag, as, Hg and Cr are highly differentiated. The features of △ t-plane isolines show a string of NW-trending positive magnetic anomalies, forming a NW-trending zonal anomaly. This paper discusses the occurrence characteristics of yejiazhuang gold deposit, and through the comprehensive application of geological, geophysical and geochemical exploration methods, it is concluded that the gold deposit in this area is a low-temperature hydrothermal altered semi concealed ore body. The discovery of yejiazhuang gold deposit indicates the next direction for gold exploration in Xiahe group.<br>
