Characteristics of Primary Halos and Prognosis of Concealed Ore Bodies in the Hongshi Gold Deposit, Xinjiang
新疆红石金矿床原生晕特征与隐伏矿预测

Based on field investigation of the Hongshi gold deposit and summarization of its geological features, the authors made a special study of the distribution characteristics and regularity of primary halos in this ore deposit by using different calculation methods, and found that the axial zoning sequence of the primary halos in the deposit is Bi-Mo-Hg-Zn-Pb-Ag-As-Cu-Sb-Au. A comparison with axial zoning sequences of other typical gold deposits in China reveals that the axial zoning sequence of primary halos in this ore deposit is obviously characterized by reversed zoning. The zoning evaluation model and the ore body superimposition pattern for this ore deposit were also set up so as to predict concealed ore bodies in the depth.
