MULTI FRACTAL METHODS RESEARCH IN DATA PROCESSING OF IN-SITU X-RAY FLUORESCENCE
摘要
Abstract
The information extraction of geochemical a-nomalies data is the core task of the geochemical exploration. Using different ways to extract unusual information that differences will make the striking influence on anomaly scope. The article takes the in-situ X-ray fluorescence geochemical exploration soil sample data as an example in mountain of western Tianshan area of Xinjiang to try to popularize the content-summation method of multi fratical methods to fit calculation the five period of lineaments. According to the results, it is ensured that the lower limit of positive anomaly and the upper limit of negative anomaly of the As and Sr in study area. Combining with regional geological background of anomaly comprehensive explanation of the study area, and comparing with the traditional statistics method of delineating anomaly range, it was found that five zones fitting content-summation method get the high consistency on the positive anomaly delineated results, and make the expected effect in delineating the negative anomaly.关键词
