| Abstract: | Blind signal extraction arithmetic was used to extract abnormal geochemical data. The geochemical concentration was determined by fractal content - grads method. The data from Lasa hydrographic deposits in Tibet were processed by this method. The concentration focus and the mineralized distribution are coincident with actual state. The result shows the practicality and validity of this news method. |
