摘要:Abstract(#br)Many years have passed since previous national seismic hazard maps were prepared for South Africa. In those maps, zone-less techniques were applied. The availability of more reliable seismicity and geological data has made it possible to update those maps using proba...

摘要:Abstract(#br)Structural geometry of the Komombo basin was demonstrated using 2D seismic data. Komombo basin appears as two, left-stepping, en-echelon half grabens separated by a NNE oriented broad anticline dissected by NNE oriented oblique-slip faults. The developed fault p...

摘要:Abstract(#br)The Ouansimi copper deposit, located South of the Kerdous inlier in Morocco, is an example of vein-type mineralization hosted in the Adoudou Formation limestone of the Lower Cambrian Taroudant Group. The copper-bearing veins are mainly controlled by Variscan NNW...

摘要:Abstract(#br)This study presents a method to map the risk of submersion of the lower Tunisian coasts, by taking as an example the coastal sabkhas system of a part of the bottom of the gulf of Hammamet between the sabkhas of Sidi Khlifa and Halq El Minjel. Total Water Levels (TWLs...

摘要:Abstract(#br)Supergene alunite from a supergene leached capping zone in the Daero Paulos area near Asmara, Eritrea yields Thanetian (late Paleocene) K–Ar ages of 58.6 ± 2.3 and 59.4 ± 2.3 Ma. The leached capping is exposed in an erosional window through a laterite profile, w...

摘要:Abstract(#br)Around the city of Cape Town, South Africa, the basal Neoproterozoic rocks are poorly exposed. There is however, historical evidence for good exposure of these rocks on the seafloor of Table Bay, although not mapped at sufficient resolution nor areal extent for ...

摘要:Abstract(#br)This work examines the structure and tectonic setting of the possibly late Neoproterozoic - early Cambrian Pan-African (henceforth Pan-African) Chingale Igneous Ring Complex (CIRC) in southern Malawi to document its internal emplacement structure and solicit imp...

摘要:Abstract(#br)Endothiodon is amongst the most cosmopolitan, easily identified and bizarre genera from the middle/late Permian. Its complex and unique feeding system with continuous replacement waves of teeth and its cranial morphology make it stand out among dicynodonts. Our incre...
