lake via the Bosporus. The inflowing dense seawater created a physical and chemical boundary, the chemocline, separating oxic surface water from hydrogen sulfide-bearing deep water. The speed and nature of the post-glacial seawater inflow remains a matter of debate, with the most drastic scenario envisioning a rather catastrophic flooding of the Black Sea shelf and presumed dramatic consequences for the coastal inhabitants of that time. Based on coeval geochemical signatures in several sediment cores retrieved from different locations in the Black Sea, Eckert et al. were able to reconstruct the vertical migration of the Black Sea chemocline. They found that, contrary to the great flood hypothesis, the chemocline rose rather slowly and inundated the shelf in at least two distinct steps since the last glacial.
Exhumation history of the Andean broken foreland revisited Federico M. Dvila, CICTERRA-CONICET, Universidad Nacional de Cordoba, Cordoba, Argentina; and Andrew Carter. Posted online 7 Feb. 2013; http://dx.doi.org/10.1130/G33960.1.
In west-central Argentina, to 400-800 km from the Peru-Chile Trench, subduction is shallow. Such tectonic scenarios are appropriated to produce increases in rock uplift and exhumation, where thrusting and dynamic forces work together. Nevertheless, a prevalence of pre-Cenozoic apatite fission-track cooling ages suggests that there would have been such link in Argentina. Reinterpretation of published AFT exhumation data (more than 320 ages) using more realistic lower geothermal gradient values allows for substantial exhumation and explains the lack of Cenozoic exhumation ages across the foreland. Flat subduction would have removed the mantle wedge, a significant source of heat flow into the crust.
