Figure 11. Sequence of brittle deformation events in well B based on crosscutting relationships. (A) Collapse breccia cemented by radiaxial-fibrous calcite rims around clasts. Breccia pores are filled by microcrystalline infill and silica. Wide veins also show internal brecciation and crack-seal texture. (B) Faulting, several generations of breccias and microbrecciation. Breccias have clasts from host rock and are commonly rebrecciated. (C) Quartz veins and barite geodes, which sometimes show solid bitumen fill.
