Time 2 (T2) after deposition of the Stephen Formation; mixed brines form Replacement Dolomites 3 and 4, and this reduces the porosity of the fault damage zone. Time 3 (T3) saddle dolomite-cemented breccias develop due to overpressures caused by shallow burial and low porosity and permeability replacement dolomite.

Mixing of seawater and serpentinite-derived brine occurred in the Gog Group before migrating upwards along faults and dolomitizing the Cathedral Formation. Mixed brines ultimately discharged at the platform margin where brine pools formed throughout the Middle Cambrian.
