Validation of SRTM in the region of the Great Lakes
The aim of this study is to establish whether or not SRTM meets its modal requirements in Central Africa. We use as a reference the geodetic network and leveling points available for Eastern DRC, as well as a local topographic map (scale 1/5,000 o...

Situation de la frontière dans la région de Kahemba
The actual position of the border in the Kahemba region is discussed on base of the surveys....

Mise à jour du réseau géodésique du Nord de la RDC
There is no geodetic network available for the North and Northwest of DRC. A small project is described aiming at upgrading the presently available data (mainly astronomic points), especially in the vicinity of the Congo river....

Géocodage des images Google Earth
Although intrinsically geocoded, the images provided by Google Earth are devoid of projection identification and parameters. This paper identifies the projection used by Google Earth and the relevant parameters, thus allowing for a complete geocodin...

Madagascar volcanic provinces linked to the Gondwana break-up: geochemical and isotopic evidences for contrasting mantle sources
After the Gondwana break-up and Greater India splitting off, Madagascar suffered volcanic episodes. The Cretaceous Morondava flood basalt (CFB) province was emplaced ca. 93 Ma ago. Two coeval high-Ti–P (HTP) and low-Ti–P (LTP) suites ar...

Nature, origin and significance of the Fomopéa Pan-African high-K calc-alkaline plutonic complex in the Central African fold belt (Cameroon)
The Fomopéa plutonic complex in West Cameroon comprises three petrographical units: a biotite–hornblende granitoid (BHG) including some diorite, a biotite monzogranite (BmG) and an edenite syenogranite (EsG). Amphibolites occur within each un...

Sr–Nd isotopes and geochemistry of granite-gneiss complexes from the Meatiq and Hafafit domes, Eastern Desert, Egypt: No evidence for pre-Neoproterozoic crust
Neoproterozoic gneisses at Meatiq and Hafafit in the Eastern Desert of Egypt give Rb–Sr and U–Pb zircon ages of 600–750 Ma. These gneisses are interpreted by different workers to represent deeper levels of juvenile Neoproterozoic ...

Flow of Canary mantle plume material through a subcontinental lithospheric corridor beneath Africa to the Mediterranean: Comment
We contend that fi eld and geochemical evidence does not favor mantle plume fl ow under the Atlas mountain range. Early Paleocene to late Pleistocene alkaline volcanism and post-Miocene Atlas thermal uplift, though partly disconnected in time, res...

Sr-Nd isotopes and geochemistry of granite-gneiss complexes from the Meatiq and Hafafit domes, Eastern Desert, Egypt: No evidence for pre-Neoproterozoic crust
Neoproterozoic gneisses at Meatiq and Hafafit in the Eastern Desert of Egypt give Rb-Sr and U-Pb zircon ages of 600-750 Ma. These gneisses are interpreted by different workers to represent deeper levels of juvenile Neoproterozoic crust or Archaean/...

Repeated granitoid intrusions during the Neoproterozoic along the western boundary of the Saharan metacraton, Eastern Hoggar, Tuareg shield, Algeria: An AMS and U-Pb zircon age study
The N-S oriented Raghane shear zone (8°30′) delineates the western boundary of the Saharan metacraton and is, with the 4°50'; shear zone, the most important shear zone in the Tuareg shield. It can be followed on 1000 km in the basement from s...
