Precambrian granites

Mwanza, located along the southern shore of Lake Victoria, is Tanzania’s second largest city and one of the fastest growing cities in the world. It is nicknamed “the Rock City” due to the numerous hills covered with granite boulders that stretch out into the lake, creating a unique landscape. Many of the city’s houses are built around the boulders and some use granite from the rocks. The granites of Mwanza are Precambrian and belong to the stable continental crust of the Tanzania Craton.
