Rock deformation in magma-hydrothermal systems: the nature of fractures in plutons and their host rocks. Technical progress report
The geometry of magma chambers and their fracture networks is of fundamental importance to studies of the emplacement and cooling of magmas in the earth's crust. Because failure surfaces in magma-hydrothermal systems accumulate over a relatively long time, the total population of fractures is composed of several discrete fracture sets. This phenomenon has rendered the traditional mapping methods inadequate. We have developed and verified a mapping method that is capable of transferring information from fracture surfaces in outcrop into data structures that are displayed by computer-graphics techniques. These computer-images of the real system can then be compared with images of data structures generated by numerical modeling of the system's dynamic history.
