勘查地球化学工作述评

当前勘查地球化学的主要任务是评价低缓异常或不明显的弱异常。为此,须在区域成矿规律指导下,将化探信息与其它地质、物探信息结合,建立化探信息之间的系统关联,评价低缓异常和难识别异常。为了达到以上目的,应加强以下几方面的研究:地质是化探工作的前提;多种化探方法配合使用,化探信息的系列化研究;以地质体为单元处理化探数据;化探信息充分与其它信息结合。

REVIEW OF THE EXPLORATION GEOCHEMISTRY

In this paper a review of the develpment of exploration geochemistry in the past 25 years is presented. Since the exploration geochemistry was set up, it has been improved a lot not noly in its theory but also in its technique. So far as the study of the exporation has been gradully changed from appraising anomalies becomes harder and harder.Now it needs specially to study the exploration geochemistry in the following hands.1. geology is the neccessary precondtion for exploration geochemistry;2. comprehensive application of exploration geochemical methods;3. systematic study of exploration geochemical information;4. data processing based on geological body samples;5. further connection between geochemical information and other comprehensive geological information.
