Spatial distribution features of Ag, Ag-Pb, Au, Mo and Pb deposits (mineralization spots) in Xiong' er Mountain, western Henan Province, and their implicatiotion for prosoecting
摘要
Abstract
Spatial distribution features of 121 Ag, Ag-Pb, Au, Mo and Pb deposits (mineralization spots) in the Xiong'er Mountain were analyzed, and their implications for prospecting were discussed. Most of them lie in east and west parts of the Xiong' er Mountain in longitude direction; however, there are two sections (111.45 ' ～111.50° and 111.60°～111.65°) that display the lower frequency deposit (mineralization spot) locations in middle Xiong'er Mountain. In latitude direction, most of deposit (mineralization spot) locations are clustered in the middle part (34.1°～34.25°). The altitude values of 121 deposits (mineralization spots) (altitude of raining adits) fall into three altitude ranges, i.e., 600～750 m, 800～1 050 m and 1 100～1 200 m, and the altitudes of large Ag-Pb, Au and Mo deposits located in east and west parts of the Xiong'er Mountain process the similar altitude range. Six mineralization belts with different strikes and mineralization types are composed of 121 deposits (mineralization spots), the Ag and Ag-Pb belt (Ml) and Au (Mo, Pb) belt (M3) strike NW, the Au (Mo, Pb) belt (M2) strikes NE, the Pb-Au (Mo) belt (M4) strikes EW, the Au belt strikes NWW (M5) and the Au (Mo, Pb) belt (M6) strikes NS. Strikes of six mineralization belts are consistent with regional faults. The spatial distribution of 121 deposit (mineralization spot) locations show bi-fractal clustering characteristics with two non-scale ranges. Equidistant feature of ore concentration areas in the Xiong'er Mountain was found, and the distance is about 10 km. On the basis of transmagmatic fluids theory, the potential prospecting targets in the Xiong' er Mountain were discussed.关键词
