Abstract

The Karoo Supergroup (KSG) is a geological unit of great importance in Southern Africa, consisting of sedimentary and igneous rocks. The deposits of the Karoo, which are well represented in Tete Province (Central West of Mozambique), have been studied mainly to due its coal deposits. In this work 12 samples were studied from ETA 15 and ETA 71 boreholes (ca. 30 m depth), that crossed the Matinde Formation. The age and maturation of the sections in the two boreholes were determined by means of palynology and vitrinite reflectance (supported by the study of spore fluorescence and colour). Palynological results indicated a latest Permian age and the vitrinite reflectance values measured range from 1.39 to 1.5 %Rr corresponding to bituminous coals with low to medium volatiles in terms of coal rank. The results of this study are compared with existing palynological and maturation data obtained from others boreholes of the same basin.
