Orogen styles in the East African Orogen: A review of the Neoproterozoic to Cambrian tectonic evolution.
Harald Fritz,Mohamed G. Abdelsalam,Kamal A. Ali,Bernard Bingen,Alan S. Collins,Abdel-Rahman Fowler,Woldai Ghebreab,Christoph Hauzenberger,Peter R. Johnson,Timothy M. Kusky,P.H. Macey,S. Muhongo,Robert J. Stern,Giulio Viola +13 more
TL;DR: A first phase of ocean closure and accretion of terranes defines the East African Orogeny, which mainly affected the southern parts of east Africa and Madagascar, and was followed by extension phases that were accompanied by emplacement of late- to post-tectonic granitoids.
Journal ArticleDOI
Lineament characterization and their tectonic significance using Landsat TM data and field studies in the central highlands of Eritrea
Semere Solomon,Woldai Ghebreab +1 more
TL;DR: In this paper, the authors mapped lineaments in the central highlands of Eritrea using various Red-Green-Blue colour combinations and panchromatic Landsat Thematic Mapper (TM) images.
Journal ArticleDOI
Constraints for timing of extensional tectonics in the western margin of the Red Sea in Eritrea
TL;DR: In this article, apatite fission-track thermochronologic data were measured for 22 Pan-African rock samples to constrain the rifting history in eastern Eritrea, and they identified late Oligocene-early Miocene cooling coincident with extension and erosion along the conjugate margin in Yemen.
Journal ArticleDOI
Red Sea extension influenced by Pan-African tectonic grain in eastern Eritrea
TL;DR: In this paper, the Red Sea escarpment in eastern Eritrea is characterized by steep penetrative foliation S1, which is axial planar to upright F1 folds, and F2 recumbent folds and subhorizontal shear zones during PAD2 and PAD3 deformation.
Journal ArticleDOI
Modeling heterogeneous stretching during episodic or steady rifting of the continental lithosphere
Genene Mulugeta,Woldai Ghebreab +1 more
TL;DR: In this paper, the geometry of brittle-ductile extension and modes of normal faulting during steady or episodic rifting of the continental lithosphere are investigated by analogue modeling using the centrifuge technique.
