内蒙古白云鄂博群金矿综合地质信息预测

Abstract

Abstract:

Baiyun’ebo Group is an important ore-bearing strata in central-western of Inner Mongolia. It contains rare earth metals, iron, gold and other elements and has good ore-forming potentials. Mineral resources of more than 30 metallic elements, such as niobium, tantalum,uranium, thorium, tungsten, molybdenum, antimony, silver, copper, lead, zinc, manganese and so on have been discovered in the group. Through comprehensive study of geological, geophysical, geochemical, remote sensing data and their corresponding interpretating results，a stratabound gold deposit model of the Baiyun’ebo Group is established for gold deposits in Baiyun’ebo districts. A variety of varibles closely related to gold-mineralization have been selected. Based on GIS, sites of gold mineralization is forecasted using the weights of evidence approach and the amount of resources is estimated using the volumetric method of comprehensive geological information of the ore deposit model. 57 smallest forecasted areas are delineated and 402 834 kg gold is predicted.

Key words: deposit model, Baiyun’ebo Group, mineral resources prediction, weights of evidence approach
