Abstract

Abstract:

The Yongxin gold deposit is one of the major prospecting achievements in recent years in the periphery of the Duobaoshan ore concentration area in Heilongjiang Province. It is the first discovered large-scale epithermal-type gold deposit related to the Nenjiang-Heihe mélange belt. The orebody has dip angle of 20°-30°, strictly controlled by structures, and extends over 400-meter long and nearly 1,600-meter deep. Deep exploration shows that the orebody is obviously thinner and the grade is lower. To further clarify the mineralization potential at depth and guide future exploration, the tectonic superimposed halo samples were taken in different exploration lines of the mining area for geochemical analyses. The geochemical statistical analysis shows that the element assemblage at Yongxin comprises Au, Ag, Pb, Mo, W, Bi, Mn and Te, among which Au is the most direct and important indicator for the formation of gold orebodies and Ag-Te is an important associated element. Based on the axial distribution characteristics of the inner, middle, and outer zone anomalies of each indicator element in the orebody, the axial zoning sequence of orebody halo at Yongxin is established: Sb-As-Hg → Ag-Au-Te-Pb-Zn-Cu → (Bi)-Mo-Mn-Co. Among them, Sb-As-Hg are the frontal halo indicator elements, Ag-Au-Te-Pb-Zn-Cu are the near-ore indicator elements, Mo-Mn-Co are the terminal halo indicator elements. The orebody axial characteristics show that the frontal-terminal halo coexists in the margin of orebody, indicating possible existence of orebody in deep structures. According to the prediction mark of tectonic superimposed halo and geological mark, a concealed ore prediction target and a favorable ore-forming site are proposed on the horizontal projection map. The targets are located between No. 205 and 225 exploration lines, whilst the favorable ore-forming sites are located between No. 235 and 245 exploration lines. Both show the coexistence of frontal and terminal halo in the middle and lower parts of the orebody, and the anomalies of frontal and near-ore elements are obviously stronger than those of the terminal halo elements. This indicates that the orebody extends downward significantly, which shows that it is worthy of further deep exploration.

Key words: structural superimposed halo, geochemistry, deep prospecting prediction, Yongxin gold deposit, Duobaoshan region, Heilongjiang Province
