摘要
在化探工作中,正确地确定地球化学背景值和异常下限值至关重要,本文根据矿化作用产生的元素带入、带出等不同情况提出不同的计算方法。
An accurate determination of geochemical background and threshold values is of great importanceto geochemical prospecting. It is well-known that during mineralization some elements are brought inand some others are carried away. Based upon this circumstance, computational method may be used todetermine the geochemical background and thresthod values respectifully and geochemical anomalies delineated with these data will be in conformity to the practical geological conditions.
