地壳流体与地幔流体间的关系

通过铀、金矿床及地幔岩捕虏体研究，初步得出以下认识：（１）在热液作用中岩浆分异热液是不存在的；（２）碱交代作用是整个地幔交代作用和地壳交代作用的基本运作机制，现已构成有几十条具体规律的理论系统；碱交代岩是地幔流体转变为热液的化石记录；（３）拆离断层构造体系是地幔流体上升到地壳后的活动通道；（４）磷（Ｐ）是地幔流体的特征性示踪成分；（５）大洋缺氧事件、生物种属灭绝、厄尔尼诺等有共同的地幔流体致因；（６）天然气－油－盐－金属成矿是统一的热液成矿作用。软流体是今后区域成矿预测的重要新依据。软流体的顶部发育有次级、再次级的局部上凸部，这是矿带、矿田群的重要成矿控制因素和找矿新标志。

THE RELATIONSHIP BETWEEN CRUST FLUIDS AND MANTLE FLUIDS

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.
