ON THE NAPPE STRUCTURE OF NORTH-EAST SHETLAND

Abstract

The metamorphic region of Madagascar has much in common with the “Mozam- bique Belt” of East and Central Africa, although the grade of metamorphism seen is often higher. No clear comparison can be drawn between the main subdivisions of the Madagascar Basement and those of the mainland; moreover, the unconformably overlying Crystalline Limestone Series has no known counterpart in Africa, while the major late Pre-Cambrian or Lower Palaeozoic sedimentary systems of the mainland, frequently but little altered or disturbed, are not represented in Madagascar, although there is a widespread Quartzite Series, ascribed to the Devono-Carboniferous, of somewhat different character.
