It unconformably overlies folded Cambrian to Devonian See table of contents rocks and is unconformably overlain by the mid-Carboniferous Bonaventure Fonnation. The erosional remnant includes the lowest 60 m of this newly identified formation of unknown thickness.

Groundwater calcrete formation has Atlantic Geoscience Society partially or completely transformed the lowest 30 m of the sequence.

D’après sa morphologie générale et sa position stratigraphique, il est peu probable Atlantic Geoscience Society qu’Iocrinus? maennili fasse partie de la famille Iocrinidae (ordre Disparida), une famille disparue à la fin de l’Ordovicien.

New crinoids from the Chaleurs Group, West Point Formation (Ludlow to Pridoli?; Upper See table of contents Silurian) of the Gaspé Peninsula include Iocrinus? maennili (Yeltysheva) (otherwise known from the Katian of Estonia), Bystrowicrinus (col.) depressus sp. nov. and Cyclocyclicus (col.) sp. aff.

On the basis of Publisher(s) both its gross morphology and stratigraphic position, Iocrinus? maennili is unlikely to be an iocrinid disparid, a family that became extinct at the end of Atlantic Geoscience Society the Ordovician. The trivial name has hitherto been erroneously spelled as männili, mannili and mjannili. Most specimens of the common Bystrowicrinus ISSN (col.) depressus appear cyclocyclic because the pentastellate lumen occurs in a deeply sunken claustrum that is commonly occluded by sediment; clean 0843-5561 (print) specimens are highly distinctive. Cyclocyclicus (col.) sp. aff. C. (col.) echinus is 1718-7885 (digital) similar to a species known from the Katian of North Wales. Taken together, this assemblage is more reminiscent of Katian strata (Upper Ordovician).

  • Understanding Himalayan Denudation at the Catchment and Orogen Scale
    Understanding Himalayan Denudation at the Catchment and Orogen Scale Dissertation von Stephanie M. Olen Kumulative Dissertation zur Erlangung der Würde des akademischen Grades Doktor Rerum Naturalium (Dr. rer. Nat) in der Wissenschaftdisziplin Geologie Eingereicht an der Mathematisch-Naturwissenschaftichen Fakultät der Universität Potsdam Potsdam, Oktober 2015 Published online at the Institutional Repository of the University of Potsdam: URN urn:nbn:de:kobv:517-opus4-91423 http://nbn-resolving.de/urn:nbn:de:kobv:517-opus4-91423 This work has not been submitted to any other institution of higher education, and that it was prepared independently and exclusively with the specified funds, the graduate school GRK1364 “Shaping Earth's Surface in a Variable Environment: Interactions between tectonics, climate and biosphere in the African-Asian monsoonal region” of the German Science Foundation (DFG, Deutsche Forschungsgemeinschaft; Project GRK 1364/2) and by the HIMPAC research project (Himalayas: Modern and Past Climates), funded by DFG (STR 373/27-1 and 28-1). ii Abstract Understanding the rates and processes of denudation is key to unraveling the dynamic processes that shape active orogens. This includes decoding the roles of tectonic and climate-driven processes in the long-term evolution of high- mountain landscapes in regions with pronounced tectonic activity and steep climatic and surface-process gradients. Well-constrained denudation rates can be used to address a wide range of geologic problems. In steady-state landscapes, denudation rates are argued to be proportional to tectonic or isostatic uplift rates and provide valuable insight into the tectonic regimes underlying surface denudation. The use of denudation rates based on terrestrial cosmogenic nuclide (TCN) such as 10Beryllium has become a widely-used method to quantify catchment-mean denudation rates.
