Abstract
Summary: Preliminary Rb-Sr whole-rock isotopic analyses of some East African granulites give the following ages and initial ratios: The initial ratios, at the 0.705–0.706 level, conform with a world-wide pattern found for granulites and other deep crustal rocks. The whole-rock ages are the first such study on East African granulites. They confirm in West Nile the suspected early Pre-Cambrian age of the Uganda basement, and in Tanzania raise source rock problems which involve the Mozambique Front.Keywords
