Abstract

The Nampula Block is the largest Mesoproterozoic crustal domain in northern Mozambique, covering\ud >100,000 km2 and constituting one of the most important components of the southern part of the\ud Neoproterozoic to Cambrian (“Pan-African”) East African Orogen. The Nampula Block is bounded in the\ud north by the WSW–ENE-trending Lúrio Belt and by younger rocks to the south and east. The oldest\ud rocks of the Nampula Block, the Mocuba Suite, are a polydeformed sequence of upper amphibolite-grade\ud layered grey gneisses and migmatites associated with intrusive trondhjemite-tonalite-granodiorite and\ud granitic orthogneisses
