Abstract: Abstract Detrital zircons from the upper Cambrian-Devonian sandstones (Crashsite Group; n = 485) and Carboniferous tillite (Whiteout Conglomerate; n = 81) of the Ellsworth Mountains, Antarctica record a steady supply of Neoproterozoic (“Pan-African”) orogeny (~ 550–600 Ma), Grenville (~ 1000 Ma) and Neoarchean… read more here.

DOI: 10.1016/j.marpetgeo.2017.12.023
Abstract: Abstract Thick Upper Cambrian-Lower Ordovician carbonate units in the Tahe Oilfield of northern Tarim Basin were extensively dolomitized during their diagenetic history. Petrographic examination identified three types of matrix dolomites, one type of cement dolomite,… read more here.

DOI: 10.1139/cjes-2018-0025
Abstract: In many basins, Upper Cambrian carbonate successions display intervals with a positive carbon isotope excursion (CIE) of up to +5‰. In North America, this marks the boundary between the Sauk II–III super-sequences. A Steptoean positive… read more here.
