Studies show that primary hatos of this ore deposit have the following characteristics; (1) anomalies cover a large area, and the concentration centers enclose all the auriferous breccia bodies; (2) the components are complex and show obvious zoning; (3) ore-bearing breccia and porphyry as well as compo-sitionally complicated breccia contain relatively abundant gold, which, however, is highest in pyrite; (4)trace element contents and their ratios vary noticeably with the varying extent of denudation; (5) gold and major accompanying elements migrated in the form of CM-CD or [M-HS] and, under the reduction condition of falling temperature, decreasing pressure, dilution and conversion from weak acidity to weak alkalinity, elements precipitated in order of Mo, Cu, Au, Ag and Pb, forming the main framework of the element precipitation zoning.
