Abstract High-resolution bathymetric and shallow seismic data along the northeast Red Sea margin reveal a previously disregarded mechanism for carbonate platform drowning at steep-flanked rift basin. At seafloor, salt extrusions highlight influence of extensional tectonics, with flow from southern flank Al Wajh that likely originates below. Salt-flow direction, morphology, kilometer-sized slump...

The Shiranish Formation is cropped out in several areas northern Iraq. A stratigraphic and facies study was conducted within the Duhok region to determine sedimentary environment. Three microfacies, reflecting various subenvironments different shelf parts of deep sea, have been identified Formation. Four depositional environments are identified: slope, toe shelf, deep-sea or cratonic basin. reg...

Volcanoes find a new carbon platform The geological carbon cycle assumes that carbon is emitted by volcanic eruptions and removed through various forms of burial. Mason et al. found that not all volcanic eruptions have the same source for carbon in their volcanic gas. Arc volcanic activity appears to harvest carbon from old carbonate platforms, which results in a massive difference in the isoto...

Carbonate dissolution and deposition in the deep ocean is a critical component of carbon cycle, but detailed pictures carbonate dynamics below Compensation Depth (CCD) remains poorly understood. In this study, we present ∼ 420 thousand years record content CCD IODP Site U1433 at 4.4 km water depth South China Sea (SCS). Instead carbonate-free sediment, observed that site could reach as high 40%...
