ESTIMATION OF FRACTAL DIMENSION FOR QUALITATIVE GEOLOGICAL VARIABLE AND MICRO-GEOLOGICAL ANOMALY

The paper puts forward the definite matching correlation dimension for qualitative geological variables in time and space series, the estimate method of fractal dimension and the principle of distinguishing fractal body, taking the electron microprobe analysis data of higher density and longer series on core in Bainiu chang Ag polymetallic ore deposit as an example. The paper decomposes the distinguished fractal or non-fractal body to obtain the normal and anomaly body using the undetermined linear combination autoregression process model (ALCAR model) and reveals the micro-geological anomaly characters of later stage overlapping mineralization from studying w (Co)/ w (Ni) ratio and multiple variable statistical analysis of micro-element for pyrrhotite on fractal and non-fractal body.It also discusses the relationship between the submarine exhalative sediments and non-sediments later stage overlapping mineralization of the deposit.
