Stratigraphic control and distal hydrothermal footprint of the Ursa Zn-Pb-Ag prospect, Selwyn Basin, Yukon Territory, Canada
Clastic-dominated deposits are an important source of Zn, Pb, and Ag worldwide. While it is widely accepted that the hydrothermal alteration halos around these deposits can be laterally extensive, the mineralogical and geochemical signature of the distal alteration footprint is currently not well …

Late Mississippian (Chesterian) high-frequency climate change in the Pennington Formation at Pound Gap, KY USA.
… throughout the Late Chesterian. In this clastic-dominated formation, evidence for several orders of cyclicity point to tectonic, glacio-eustatic, and climate controlled-cyclicity. Pennington Formation paleosols provide a record of climate and ecological changes for latest Chesterian time. …

Sequence Stratigraphy and Petrophysics of the late Ordovician Utica-Point Pleasant Interval in the Middle Appalachian Basin, Eastern Ohio and Western Pennsylvania
… North America. The transition from a carbonate-dominated system to a clastic-dominated system reflects the drowning of a widespread carbonate platform. The units of the Trenton Group and Lexington Limestone through Utica Shale comprise the transgressive systems tract (TST) of a large …

The evolution of a sand-rich basin-fill sequence in the Pendleian (Namurian,E1c)of North-West England
… up to 650m thick, most of which is coarse clastic material. Each of the major stratigraphic units in this sequence, namely the Pendle and Grassington Grit Groups, represents a phase of clastic input to the basins. Initially, the basins were deep marine troughs with water depths of several …
