LV Wenchao, ZHOU Yongzhang, ZHU Benduo. Multifractal Singular Value Decomposition (MSVD) for Extraction of Cu-Pb-Zn Weak Geochemical Anomaly in Wendi Area, South Qinzhou-Hangzhou Joint Belt[J]. Acta Scientiarum Naturalium Universitatis SunYatseni, 2014,53(3):134-139.DOI:
A multifractal singular value program on MATLAB platform was effectively used to delineate geochemical anomalies based on 1:50000 scale stream sediment data from Wendi area
in the South Qinzhou-Hangzhou joint belt. The separation of Cu
Pb
and Zn by the MSVD method could effectively identify Cu-Pb-Zn mineralization anomaly from the high geochemical background caused by Ag-Au deposits and extract Cu
Pb and Zn mineralization anomaly information from multi-geochemical background
including week and hidden anomalies. These anomalies extracted by MSVD method are consistent with the majority of copper
lead
and zinc ore deposits
but the Cu-Pb-Zn anomalous extracted by statistical method are not consistent with the majority of Cu-Pb-Zn ore deposits. These weak anomalies on the MSVD anomalous map are significant for further work in the unknown area. The method is very effective for mineral resource prediction in Wendi area.
