Abstract

Erhongwa intrusion lies in the eastern part of Kongguer-Huangshan fault belt. It consists of pl-bearing iherzolite, olivine gabbro,gabbronorite and leucogabbro. Most of these rocks are slightly enriched in LREE and depleted in HFSE(Nb, Ta and Ti).The primary magma of this intrusion may be ordinary tholeiite (MgO=7.3%). Element geochemistry and Nb, Sr, Pb isotope characters suggest that this magma source is composed of asthenosphere components, mixed with a small amount of lithospheric mantle components, and this magma was subjected to becontaminated about 5% by contiental crust. Compared with others intrusion in this mafic-ultrumafic belt, the Erhongwa intrusion has some significant differences in rock association, primary magma nature and assimilation,which may restrict the mineralization potential in this area.
