Characteristics of Primary Superposed Halos and Ore-Search Prospect towards Depth in the Jiagongtai Gold Deposit of Subei,Gansu Province

Meng Zhe

Abstract

Through a systematic study of primary halos in the Jiagongtai gold deposit,we have established a axiial zonation for structural superimposed halos in the mine area( from upper to lower) : W-Mo-Bi-Ni-Co-Cu-Zn-Pb-Ag-Au-Sb-As. We think that this ore-forming hydrothermal area is characterized by multi-period stacked mineralization. Numerous frontal halo anomalies exist at depth,indicating a good prospect of ore-search there. It is forecasted that the deep blind ore targets are below 3200 m nominal elevation.
