Figure F50. Plot of downhole distribution of void secondary minerals and filling (%) for each alteration interval defined by the alteration petrology group. Circles are located at center depth for each interval. Carbonates (blue circles) are the main phase in the uppermost 300 m, whereas zeolites (purple circles) dominate in the lowermost 200 m. Filling with dark clay (orange plus symbols) becomes more abundant with increasing depth. Pink and green shading represent oxidized and reduced conditions of host rock alteration, respectively.
