初论地球化学成矿预测系统工程

勘查地球化学发展至今,其主要任务是评价低缓异常或不明显的弱异常。为此,单凭传统的异常找寻和评价方法,难以达到地球化学找矿的目的。本文试图以地球化学理论体系和方法论为基础,从系统工程角度阐明地球化学成矿预测的系统性。在系统性指导下,开展地球化学预测,主要包括三个方面的内容：地球化学理论体系和方法论；地球化学预测是分级预测；地球化学预测系统是综合预测系统。

A TENTATfVE DISCUSSION ON SYSTEMATIC ENGINEERINC FOR GEOCHEMICAL ORE PROGNOSIS

: Up till now, exploration geochemistry has been mainly devoted to the appraisal of low and gentle anomalies or indistinct weak anomalies. It is very difficult to attain the aim of geochemical prospecting merely on the basis of traditional methods for finding and evaluating anomalies. With the geochemical theoretical system and methodology as the basis, this. paper attempts to expound the systematicness of geochemical ore prognosis from the angle of systematic engineering. Guided by the systematicness, we could perform geochemical prediction. It consists of three aspects: geochemical theoretical system and methodology make up its basis) geochemical prognosis is the prediction at different levels; the geochemical prognostic system is an integrated prognostic system.
