Botanogeochemical anomaly characteristics of the Fuhezhong W-Sn polymetallic ore district in Guangxi and their prospecting effectiveness

Abstract：Fuhezhong area in Guangxi is one of the important W-Sn polymetallic ore districts in China. In this area, climate is warm-hot and rainy, red soil is grown, and vegetation is luxuriant. In order to probe into the effectiveness of botanogeochemical prospecting, the authors made an experiment on different types of ore deposits in this area. The results show that in all types of ore deposits, there is a good botanogeochemical composite anomaly in the upper part of the ore body. The anomaly is very distinct, its width is lager than the width of the ore body, and it has good botanogeochemical element combination and zoning. These characteristics indicate that the delineation of the botanogeochemical anomaly is an effective means for exploring mineral resources. According to characteristics of the botanogeochemical anomaly and element combination, different types of ore deposits can be distinguished from each other, the location of concealed ore bodies can be predicted, and the burial depth of the concealed ore body can be inferred.
