According to probability diagram theory,probability diagram screening software has been finished using visual basic technique.Mixed massing of ore grades in the Dongshengmiao deposit has been screened in ore to seek new information of mineralization periods.Previous results suggest that cumulative probability curve of ore grades,which belongs to one mineralization period,show a straight-line.While cumulative probability curves of four primal elements like TS,Zn,Pb,and Cu from 8 representative exploration lines of the Dongshengmiao deposit all appear one apparent point,indicating new mineralizing period information.It is concluded that two mineralization periods,middle Proterozoic syn-deposition ocean floor exhalation mineralizing period and epigenetic mineralizing period,happed in the Dongshengmiao deposit.
