应用分阶段建立地质地球物理地球化学模型的方法预测金矿远景区

Integrated Geological-Geophysical-Geochemical Model Established in a Prescribed Order for outlining Gold-ore Prospect Area

分阶段建立地质地球物理地球化学模型的找矿远景区预测方法,是把预测工作看作一个过程,包括4个阶段:(1)建立定性的地质—地球物理—地球化学综合信息找矿标志和找矿模型;(2)用各种数理统计方法在研究区中选取“模型单元”;(3)用各种数理统计方法对研究区进行找矿远景预测;(4)综合各种数理统计方法的预测结果,得到研究区的找矿远景区预测图。用上述方法成功地预测了新疆XZGR中部地区的找金远景区,指出了找矿方向。

A medel using for delineating gold-cre prospect area has been established in a prescribed order ba-sed upon a synthetical study of geological,geophysical and geochemical information.It can be lookedupon as a prognosis program,proceeding in following order:1.prospecting criteria selection and modelestablishment by the aid of integrated information collected;2. 'model cell' choosing from the studyarea by using various mathematical statisticl methods;3. prediction of prospect arca,similarly somemathematical statistical methods are used;4. prognostic map construction for the prospect area by syn-thesi:ing the results predicted by different statistical methods.The model established by above-menti-oned procedures has been successfully used for gold ore prospect area prognesis in Xinjiang.
