De Brazza's monkeys (Cercopithecus neglectus) are non-human primates (NHP) living in Equatorial Africa from South Cameroon through the Congo-Basin to Uganda. As most of the NHP living in sub-Saharan Africa, they are naturally infected with their own simian lentivirus, SIVdeb. Previous studies confirmed this infection for De Brazza's from East Cameroon and Uganda. In this report, we studied the ...

Due to the success of oil and gas production, turbidites have become exploratory targets over past 40 years in rift passive margin basins North South Atlantic. The turbiditic reservoirs settings Atlantic sedimentary located Brazil (Campos Basin) Portugal (Lusitanian represent potential economic units for hydrocarbon exploration. However, despite being considered analogous reservoirs, these pres...

The sedimentary record of Lake Malawi, one of the large rift valley lakes of east Africa, contains thick sequences of biologically undisturbed, finely laminated muds and silts. Laminated sequences were recovered in cores from the extensive diatom ooze and silty diatom clay facies of the lake basin that is permanently anoxic below 250 m. The sequences consist of light-dark laminae couplets with ...

Abstract Hormuz salt formation is considered the origin of evaporated deposits in Zagros and its ductile behavior has been known as reason for inhomogeneous deformation Zagros. However, our knowledge about this limited to domes on surface. In study, local earthquakes recorded by a temporary dense seismological network 17 stations, deployed southern margin Simply Folded Belt (SFB) southwestern I...

Although there is a general consensus on African origin of early modern humans, there is disagreement about how and when they dispersed to Eurasia. This paper reviews genetic and Middle Stone Age/Middle Paleolithic archaeological literature from northeast Africa, Arabia, and the Levant to assess the timing and geographic backgrounds of Upper Pleistocene human colonization of Eurasia. At the cen...

In this paper, we propose a texture-based interpretation workflow and apply to delineate salt domes in 3D migrated seismic volumes. First, we compute an attribute map using a novel seismic attribute, three-dimensional gradient of textures (3D-GoT), which measures the dissimilarity between neighboring cubes around each voxel in seismic volume across time or depth, crossline, and inline direction...

Abstract Turbidity currents commonly bypass sediment in submarine channels on the continental slope, and deposit lobes farther down-dip flat unconfined abyssal plain. Seafloor outcrop data have shown that transition from to deposition usually occurs over complex zones referred as channel–lobe (CLTZs). Recognition of these cores remains challenging due a lack characteristic sedimentary facies st...
