Ruoergai Gold Geochemical Anomalies In Data Processing

The essence of exploitation geochemistry data processing is the identification of the geochemistry background and geochemical anomaly and the anomalistic data processing aims at finding out geochemical information on ore from abundance of original data which were got in reconnaissance.Many methods for analytical data in chemical exploration usually regard various geo-phenomena as random variables, and data distribution as a kind of smooth curved face. These are not consistent with the nonlinear feature hinted by mineralization statistics and elements in earth crust, and not all of the geo-phenomena result from random process.This thesis has individually evaluated the unusual geochemistry phenomena from traditional method and fractal method at Axilongqu in Ruoergai on the basis of former related documents. Compared to traditional method, fractal method can determine the unusual minimum element more quickly and precisely. And the method can not only efficiently simulate the features of spatial distribution, but also reasonably differentiate the background value from the anomaly geo-chemical value on the basis of retaining primary effective information.
