Marine geology of the Cape Peninsula and False Bay
The Cape Peninsula is a peninsula that juts out into the Atlantic Ocean at the south-western extremity of the African continent. At its tip is the Cape of Good Hope. The peninsula forms the west side of False Bay. The two main rock formations are the late-Precambrian Malmesbury group (metamorphic rock) and the Peninsula granite, a huge batholith that was intruded into the Malmesbury Group about 630 million years ago.
