Geological data comprehensive analysis of Kongmolong ore section in Duocaima Pb-Zn ore deposit, Qinghai province

Through analyzing the data characteristics synthetically, the mine thickness of Kongmolong ore section in Docaima Pb-Zn ore deposit is from 2.07 m to 82.5 m, and the average ore grade is from 0.66% to 8.82%, and the Pb-Zn mixed ore grade is generally high.The useful components and the industrial mineralization degree of the seven main ore-bodies, reflected by the ore-body variation coefficient, the mineralization intensity index and the ore-bearing coefficient, are respectively uniform and discontinuous in the space distribution.The deposit thicknesses of M4, M5, M6 and M11 ore-bodies are more stable than M3, M10 and M12.In the whole mining area, the thickness of the Pb deposit is generally higher than the Zn deposit.
