The movement of fluids through rocks has profound consequences for the
transport of heat and matter within the Earth. Recently, considerable
effort has been expended in determining the mechanisms and pathways of
geological fluid flow, with much of this research concentrated on the
effects of deformation on rock permeability. Although it is well known
that fractures can act as conduits for fluid transport (as evidenced by
abundant mineral-fined veins and sheet-like igneous intrusions), the
role of ductile deformation has now been recognised as an important
factor controlling rock permeability in environments as diverse as the
mantle, the deep crust, and shallow crustal shear zones.
This book brings together review and research articles united by the
theme of deformation-enhanced fluid transport, with the aim of
emphasizing the many common roots of this important body of work.
Subjects covered include the movement of basaltic melts in the mantle;
the segregation, ascent and emplacement of granitic melts in the crust;
the flow through the crust of volatile fluids produced during
metamorphic events; and the movement of aqueous fluids through fractured
rocks near the Earth's surface.
Deformation-Enhanced Fluid Transport in the Earth's Crust and Mantle
will appeal to all geoscientists interested in the movement of fluids
through the Earth. It will prove an invaluable reference work for those
working in the field and will provide i useful introduction to this
wide-ranging and rapidly evolving area of research for non-specialists.
