| Abstract: | Through geological and statistical studies of the distribution of trace elements in different rocks and the spatial position of Yangzhai Gold Deposits, this paper presents an argumentation on the migration and enrichment of gold in mineralization process and on trace elements as indicators of gold ore deposits.It is shown that the 16 trace elements, here, based on their statistics, may be divided into 3 groups: ( 1 )inert element group (V, Ti, Or, Co, Ni); ( 2 ) rather mobile element group (Mn, P, B, Ba, Zn, Ga) and (3) mobile element group (Au, Pb, Cu,Mo, As). They can indicate respectively the characteristics of original rock composition, migmatite and mineralization.By trend surface analyses of moblie elements locations of favourable mineralizations have been pointed out. |
