Nelson Rock and Mineral Club
Good exposures of Tertiary sedimentary bed (alternating sequences of mudstones and sandstones, with rare conlomerates), showing clear bedding and dip, and minor structural features (joints). Location of first recorded fossil in NZ.
Sediments have been laid down in a shallow marine environment. Deposits show evidence of gravity flows, debris flows and storm-redepodited sandstones. The exposures are in araised, wave-cut platform.
Easily accessible from beach and sea-front footpath (Rocks Road) at low tide. Cliff sections are easily visible, but access is limited by security fences, and care is needed due to road traffic and risks of falling debris.
