Regional Metallogenic Prognosis Of Xiwulanbulang Area, Wuchuan, Inner Mongolial

The studying area is located in the centre part of Inner Mongolia. The geotectonic unit is divided to North Margin of North China Terrarce. Multi-stages of strong tectonic deformation had occurred in the area and the geologic structure is quiet complex.This paper, based on the studying of the petrologic, the lithochemical, and the geo-chemical features,expounds in detail the constitution of t crustal materials and the resources of mineralizing marterial. Through the studying of the regional geotectonic, the control of the geotectonic acting on the ores is comprehended, and the mineralizing features and patterns of the classic ores in the area are furtherly analized.Gneiss Group of Wulashan Rock suite and Dongwufenzi Group of Sertengshan Rock Suite are the important ore-hosting layers in the area. Archaeozoic and Proterozoic magmas are the important basic components of the greenstone belt in the area. The invadings of the magmas have crucial actions to the resourses and gatherings of Au element and control the distributions and scales of gold and iron ores. NE and approximately EW fracture structures and ductile shear zones control the distribution patterns of gole ore and mineralized bodies.5 minerogenic prospect zones are divided and 6 prospecting target areas are delineated by predicting mineralization and summarizing the geo-chemical and element-distributing features, the comprehensive abnormal areas of geochemical soil survey of 1/50000 scale, the genetic types, metallogenic time and metallogenic patterns of the deposits and the distributing features of the ore occurrences of the major geological units.
