Summary
… geology concerns fluids every bit as much as it does solids. That is, geology usually conjures the idea of just the rock the earth is made of; but this rock is a locus of major interactions between fluids and solids. Fluids firstly concern the environments of sedimentary deposit, which differ according to location: salt ocean water, continental fresh water, atmospheric air, to name a few. Then the movements of the water tables in the beds running along accidents, evidenced by water springs, for example, are important phenomena. The oil and gas fields that petroleum explorers look for are yet another illustration of how fluids participate in geological processes.
Biju-Duval, 2002Seabed fluid flow occurs in a wide range of oceanographic environments (coastal, continental shelf, slope and rise, and the deep ocean) and geological (plate tectonics) contexts (convergent, divergent, and transform plate boundaries, and intraplate settings). In this chapter each situation in which seabed fluid flow occurs is described. In some cases only a brief description is necessary. However, in others, particularly those that are less well known, more detail is appropriate.
