摘　　要：以地质、地球化学勘查资料为基础，探索了应用数学地质方法快速评价区域化探异常的可能性。文中分别使用了判别分析和标准矿化估值法，对新疆北部１／２０万区域化探扫面圈定的阿克塔斯金异常区进行了找矿有利地段和远景资源量的预测研究。结果表明，已知的矿化地段由０．５ｋｍ延长到２ｋｍ，合理地预测出２６ｔ的金远景资源量，显示出了该异常区的找矿前景，为在我国西北部地表露头少、地质勘探工作程度低的地区进行异常评价和找矿预测提供了一种有效的技术方法。The possibility of using mathematical geological method for the rapid evaluation of regional geochemical anomalies isdiscussed in the paper. The prospecting favourable district and gold prospective resources of Aketas anomaly area havebeen delineated by the discriminant analysis and the standard ore forming estimate method,respectively.The prospectingrange is a small minerallized belt whose length is about 0. 5km long to 2km. The total gold prospective resources areabout 26 tons. The drilling results have shown that there are a hidden fractured-alteration-type gold ore bodies in thebelt,and a more obvious effect for delineation of ore bodies by mathematical geological methods has been achived.
