DOI: 10.1016/j.apgeochem.2019.05.006
Abstract: Abstract Wet-based glacial deposits have been used traditionally as an analog for upper continental crust (UCC) abundances. To provide more information on the validity of using glacial deposits from wet-based glaciers, samples deposited by the… read more here.

DOI: 10.1016/j.gca.2018.05.004
Abstract: Abstract The upper continental crust (UCC) is an important reservoir of Ba within the Earth. We report high precision (≤±0.05‰, 2SD) Ba isotopic data for 71 samples (including granites, granodiorites, loess, glacial diamictites, and river… read more here.

DOI: 10.1016/j.gca.2019.08.002
Abstract: Abstract The concentrations of Cu and Ag, both insoluble chalcophile elements, can be used to place tight constraints on the proportion of basalts in the upper continental crust (UCC) through time via analyses of fine-grained… read more here.

DOI: 10.1016/j.marpolbul.2020.111087
Abstract: Trace metals, dichloro-diphenyl-trichloroethane (DDTs), polychlorinated biphenyls (PCBs), and polycyclic aromatic hydrocarbons (PAHs) were quantified in surface sediments from mud depocenters located in the western South Atlantic upper continental margin. There was no anthropogenic trace metal… read more here.

DOI: 10.1038/s41598-021-94492-y
Abstract: Continental crust has long been considered too buoyant to be subducted beneath another continent, although geophysical evidence in collision zones predict continental crust subduction. This is particularly significant where upper continental crust is detached allowing… read more here.
