关于开展二次资料开发的几个问题

积多年地质工作形成的各种资料和成果，包括物、化探等，都是为当时某项地质找矿任务与要求而完成的，由于地质理论水平、方法手段所限，对其蕴藏的部分或大部分信息尚未开发利用，在目前国家地勘费紧张，如何把有限的资金使用在刀刃上，即以最小投入取得最佳找矿效果，也是当前必须解决的课题。因此，对已有资料的二次或多次开发，反复研究，提高认识，作好普查第一阶段的工作，提高找矿命中率是十分必要的。

ON REDEVELOPMENT OF THE INITIAL GEOLOGICAL INFORMATION

Based upon the geological work for many years,a wealth of data and rcsults are collect-ed,including geological prospecting,geochemical exploration,etc,.Due to the limited geologi-cal theoretical level,methods and meastires,a part or most of informations collected have notbeen used up till now.At present,geological exploration outlay is not enough in our country,so,we shouldinvest capital as little as possible and make the optimal results,therefore,the data repeatedlyreused is essential to research again,for deepening our understanding,and to achieve theprospecting results,when we conduct the geological survey in the first stage.
