RB 82/00053 Geological assessment of proposed Penneshaw Harbour for Philanderer ferry service.
Well cemented slightly wrathered metasandstone (Kanmantoo Group) occurs at the site of the proposed harbour. Fracture spacings are such that when blasted the rock would form blocks of a suitable size for a breakwater. The rock is considered to be...-
