地球科学发展到今天,已要求从昔日的固体地球观向新的流体地球观转变。在动力学中流体才是最活动的因素。广义流体的含义指浆、液、气。固体只有渗透一定量的浆、气、液三者之一才有流动的可能或其应变速率加快。浆、液(主要是水)、气三者的动力学功能并不等同。无论是浆还是液均乃气的派生产物,没有气体则不可能形成浆或液。硅酸盐岩石的固体热传导微不足道。因此,在流体地球动力学中气体地球动力学乃是最有决定意义的核心问题。此气体是指地幔条件和环境中的气体,它和地壳、地表上的气体有很大不同。

At present the geoscience progress demands the conceptual change from past view point regarding the Earth as solid to one regarding the Earth as fluid or plastic. The socalled fluids (in a broad sense)includes the magmas,aqueous solution and gases. The solid can not flow unless it has been permeated by the fluids which are able to accelerate the strain rate. The three spieces mentioned above are not equivalent to each other in geodynamics. Research has demonstrated that the magmas and aqueous solution are the derivatives of the gases. The thermal conductivity of silicate solid is less efficient and very slow. So the gas geodynamics is the most vital factor in the fluid geodynamics. Here the gases infer to the mantle gases, which are basically different from the crust ones.

Key words: gas geodynamics, mantle ichor (HACONS)
