Permeability Changes Resulting from Quartz Precipitation and Dissolution around Upper Crustal Intrusions

Figure 7

Porosity changes with time in systems with an initial porosity of 0.05 and (a–e) high host rock permeability and a shallow intrusion emplacement depth, (f–j) intermediate host rock permeability and a shallow intrusion emplacement depth, and (k–o) intermediate host rock permeability and a deep intrusion emplacement depth. Vapor saturation contours are shown with solid black lines. The time after intrusion emplacement is shown above the snapshot.
