National Directorate of Geology, Mozambique
After national independence there was increased geological fieldwork in the country which resulted on identification of several new deposits. So, the civil war intensified in 1983, give no chance for cartography and mineral exploration fieldwork. During the period between 1999 up to now, in order to increase the geological database, publish and promote geological information, the National Directorate of Geology, undertake following activities:
Geological mapping of Niassa and Manica Greenstone Belts
The following geological mapping areas were covered:
From 1999 up to 2000: Ngoo, Cobue and Lupiliche in Niassa Province;
From 2002 up to 2003: sheets 1437 and 1438 in Niassa-Nampula Provinces; and
about 25.000 Km2,which covered the distrits of Cuamba, Metarica, Muoco, Nipepe, Ribáuè, Iapala, Malema and Mutuali;
Geological prospection in selected areas-Project
In 1999, the field work covered 280km² was directed to ornamental stones in Gorongosa site and two type of commercial rocks was identified:
Granito negro (olivínic gabbro and dolorito) in Mfumo Domba, Monte Ndemera, Monte Nhade areas;
Granito róseo (grannular granite and granitoides) in Serra Carabina and Serra da Gorongosa areas.
In 2000, the field work undurtake in Espungabera area and 297 km², was covered with promissing areas on granitos negros:
Basalto de Chinica, Monte Cibeche, Corneana de Rio Caja, Chirarue, Monte Chicono, Basalto do Monte Mangala.
Xisto Ardósio, sources of thermal water in Vira-Vira and Régulo Wilson zone.
In 2002, Tete Provincia was visited and covered 499 km² with:
Granitos (negro, castanho) with economic interesse in Nhatipissa, Ratoneira, Nhambia, Txisita, Buzimuana, Moatize e Catema; along Tete-Songo steet in Cahora Bassa region.
In 2003 the fieldwork was undertaken on Cahora Bassa and Changara Districts were granites was identified in Maroeira, Nditi, Cahora Bassa, Kadzipande and Thaka areas.
Geological mapping under DEVELOPMENT OF GEOLOGICAL INFRASTRUCTURE:
- Comprehensively re-map areas underlain by Precambrian rocks (Areas A, B, C, and D) on a scale of 1:250 000 and selected 1:50 000 map sheets.
- Revise the geology of the Phanerozoic rocks (Area C)
- Introduce a contemporary, systematic lithostratigraphic classification
- Produce modern geological map coverages and explanations in digital format
