Formation of a stratified subglacial "till" assemblage by ice-marginal thrusting and glacier overriding / Colm Ó Cofaigh, David J.A. Evans, John F. Hiemstra.
Title: | Formation of a stratified subglacial "till" assemblage by ice-marginal thrusting and glacier overriding / Colm Ó Cofaigh, David J.A. Evans, John F. Hiemstra. |
Author(s): | Ó Cofaigh, Colm. Evans, David J. A. Hiemstra, John F. |
Date: | 2011. |
In: | Boreas. (2011.), Vol. 40(1) (2011) |
Abstract: | Employs sedimentological techniques to test subglacial vs. subaqueous/glaciotectonite origin of diamictons at Feohanagh, Dingle Peninsula, south-west Ireland. Presents stratigraphy of sequence of glaciotectonically stacked till and outwash dominated by stratified diamictons, with strafication/lamination imparted by presence of numerous closely spaced subhorizontal and anastomosing partings, giving fissile appearance to diamictons. Proposes two-stage process in which initial glaciolacustrine sedimentation in ice-dammed lake was followed by glaciotectonic thrusting and overriding, reworking and variably deforming lake sediments. Discusses interpretation of similar late Quaternary sequences around coastal margins of Ireland and Britain. |
