THE RELATIONSHIP BETWEEN CRUST FLUIDS AND MANTLE FLUIDS

Du Letian(Geological Research Institute of National Nuclear Cooperation,Beijing, 100029)  
This paper presents the tentative knowledge on the basis of the studies of U Au ore deposits and mantle xenoliths. (1) the magma differentiated hydrothermal solutions are unreasonable; (2) the alkaline metasomatism is the key to understanding of the mantle and crust metasomatism; (3) the detachment structure is the channel of the upwelling mantle fluids; (4) the phosphor(P) is the characteristic tracer component of mantle fluids; (5) the ocean anoxic events, El Nino and black shales have the common causes (HACONS upwelling effects); (6) natural gases oil oil shales salts hot brines hydrothermal ore formation constructed oregenesis systems, which are the derivatives of HACONS. The asthenospheric bodies and low velosity zones can be considered as the new prognostic targets.
