Parnell Grit outcrops at the Northern end of the beach. Collecting should be restricted to below the high tide mark. Zeolitised clasts in the beds are derived from the Manukau stratovolcano with some input from the Kaipara stratovolcano - both of these are of Miocene age and apart from the uplifted fault block forming the Waitakere Ranges they are not exposed and are only inferred from magnetic anomalies.
