文摘
- •
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.
