Released by way of the yankee Geophysical Union as a part of the Geophysical Monograph sequence. This quantity deals a pattern of the range of study on faults and fluid circulation within the past due Nineteen Nineties. It describes targeted floor and subsurface characterization of fault-zone constitution and diagenesis with implications for hydrology and petroleum geology; the position of faults in geothermal platforms; laboratory stories of rock mechanics, permeability, and geochemistry of faults and fault rocks; and mathematical modeling of fluid circulate via faulted and fractured rocks.
