Rare field opportunity to study basin-scale normal fault zone reactivated in compression.
Fault zone structure in basement controlled mainly by host rock lithology and anisotropy.
Hanging wall laced by networks of steeply-dipping pseudotachylytes.
Fault core contains progressively foliated fault rocks rich in chlorite and muscovite.
Frictionally weak core facilitated steep reverse faulting and acted as hydrological barrier.
