Abstract:

Gold deposits are of low-exploration and study degree in the Tianzhu-Jinping-Liping area, southeastern Guizhou Province. To carry out mineral prediction of gold mineral resources in this area, some special topic studies should be concerned such as the geological background, metallogenic regularity, geophysical, geochemical and remote sensing, prospecting indicators, etc. Some main factors affecting mineral prediction, for example, the geological background and metallogenic regularity must be identified. When the prediction conditions are not ripe in these areas, the potential assessment of mineral resources in ore field or deposit scale can be carried out, the prospecting perspective of each gold field can be evaluated and the possibility to find new deposit can be analyzed. The authors use the sum of weight of various forecasting elements to locate predicted mineral resources, instead of carrying out quantitative prediction based on GIS, intended to emphasize the importance of special topic researcher, and to explore the possibility of simplifying the process of mineral prediction. The simplified process of the location prediction for ore fields that suitable for this area includes studying on related topics and prediction elements, calculating the probability of mineral occurrence, classifying exploration prospective area and potential assessment of mineral resources for ore fields. According to this method，ten prospecting areas are determined including four class A,three class B and three class C.
