The GIS-Based Appraisal Of Favorableness To Ore-Forming Of Tungsten Ore In Southern JiangXi Province

The tungsten ore deposit can be divided seven kinds of types in southern Jiangxi Province. In these seven kinds of ore deposits type, quartz vein-type is the most important type, and the skarn-type and intrusive body-type are next. The breaking alteration breccia-type tungsten ore deposit is a new ore deposit type in southern Jiangxi Province.The stratum, intrusive rock, and faulted structure are three basic ore-forming geology factors of tungsten ore in the work area. Their spatial distribution exists objectively. Their influence to the ore-forming exists objectively. Therefore, they are the foundation of ore-forming prognosis.We collected mass data and established spatial data by the layer classification which used to appraise ore-forming favorableness.The paper gives the reasonable and favorable ore-forming area by GIS space analysis. It has an assistant reference value in decision-making.This work indicates that appraisal of ore-forming favorableness based on GIS is a new effective method in Ore-forming prognosis.
