| Abstract: | The Ore-bearing diorite in Yanshan region is dominated by metamorphic diorites intruded during Proterozoic. They are characterized by the early time of intrusion, poor differentiation (D.I=44.18) higher value of CaO, Cr2O3 and V2O5, lower Value of TiO2, higher ratio of Na2O/K2O(2.42-5.36) and Sr/Ba (1.62), lower ratio of Rb/Sr (0.06) and Au/Mn (0.06), lower value of TREE (102.72ppm) and lower LREE/HREE (3.88), lower ualue of Au, Pb, Zn as well as alkalinity cofficient(A.F)(44.8) |
