谈谈地球化学勘查的合理程序问题

本文根据地矿部各省地矿局近年来提供的采用化探方法找到的各类矿床的发现史讨论地球化学勘查的合理程序问题.作者根据地矿部各省局采用化探方法找到的各类矿床的找矿案例中总结了四类化探勘查程序,并分别对四类程序的特点和问题进行了讨论.作者一方面强调了在成矿运景区内的化探普、详查选区要有前期化探资料为依据,另一方面也指出了勘查程序并不是一成不变的,常常要根据一项勘查工作的要求、资金保证程度和异常检查情况等多种因素设计和确定最佳的勘查程序.

A DISCUSSION ON RATIONAL PROCEDURE IN GEOCHEMICAL EXPLORATION

According to abundant case histories concerning discovery of various sortsof ore deposits using geochemical prospecting methods provided recently bybureau of geology and mineral resources of various provinces, MGMR, the pres-ent paper deals with the topic of rational procedure in geochemical explorati-on. From summarization of these case histories, the author has drawn four ty-pes of procedures for geochemical exploration, with a discussion given on theitrespective characteristics. While emphasizing the necessity that the geochemi-cal reconnaissance and detailed exploration in an ore prospect area should bebased on previous geochemical prospecting data, the author points out that theexploration procedure is not unchangeable, and that the optimum explorationprocedure should de designed and fixed on the basis of varied factors such asrequirements for an exploration project, funds available and anomaly examination.
