Geophysical and Geochemical Anomalous Features of lead and zinc De-posit in Amuyilete, Inner Mongolia and Its Geological Significance

Amuyilete Pb-Zn deposit of Inner Mongolia belongs to the west extension of Chaobuleng-Lizigou polymetallic metallogenic belt, which was found in 2005 when 1:50 000 mineral geological survey was undertaken by Geological Survey Institute of Inner Mongolia. The geochemical anomalous element assemblage is mainly com-posed of Ag, Cu, Cd, Mo, Zn, Pb, As, Sd and iron group elements. The comparison between the 1:50 000 and the 1:10 000 soil surveys shows that the reproducibility of anomaly is very well with the increased strength and the clear concentration center. It is in good agreement with the surface mineralization alteration zones. However, there is no polarizable body existed via the conventional geophysical induced polarization area survey. To detect deep con-cealed deposits, CR profiles have been arranged combined with the geological characteristics and achieve a great result. In summary, it is to provide references of carrying out further prospecting work in this area that we shall summarize the geological, geophysical and geochemical features in the deposit and the metallogenic regularity.
