Bukavu, on the south coast of Lake Kivu in the Democratic Republic of the Congo, suffers from slow but never ending landsliding. This leads to the continuous degradation and destruction of houses, buildings and of the roads, waterworks and sewerage i

In the GARS project (UNESCO-IUGS) concerning Eastern Africa, satellite images (LANDSAT-MSS and -TM, SPOT XS and P) have been processed and geologically analysed in combination with a spectro-radiometric and a geological control survey. Generally, spe

Seventy years of gold mining in the North Zaire region resulted in a total output of ca. 350 t of metal, half of this amount coming from recent placer deposits. All deposits are linked to volcano-sedimentary series and associated granitoid bodies con

Petrological studies based on core drillings have shown that two main factors have contributed to the gold mineralization in the district of Mongbwalu: 1) Plutonic activity of a granitic or a dioritic magma, resulting in a first concentration of the
