Seismic reflection imaging of mineral systems
... Identifying fluid source regions in seismic images may be difficult. The dehydration of a large area of crust to create mineralising fluids will not necessarily leave an observable physical imprint on the rocks that distinguishes that region from any other region, especially in metamorphic rocks. T ...
