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

Figure 10

Vertical fluid mass flux in intermediate permeability systems with a deep intrusion and primary porosity of (a) 0.1, (b) 0.05, or (c) 0.025. The initial intrusion boundary is shown with the thin dashed line. The snapshots are all taken at the same time (10 ka). The black lines denote the location where permeability is less than 2·10⁻¹⁶ m². Vapor saturation contours are shown with solid black lines. The yellow and pink stars denote the locations which are plotted over time in Figure 13.
