Furthermore, previous mapping has suggested that the orthogneiss and host rocks may be overlain by Mississippian clastic rocks along a prominent unconformity. Our work has included detailed mapping, U\/Pb detrital zircon geochronology, and geochronology of additional granitic orthogneiss bodies. Our goals are to (1) test the idea of a sub-Mississippian unconformity to better constrain palinspastic restorations of the pre-orogenic continental margin and better understand the development of the Cretaceous orogen, and (2) use the basement rocks to better constrain the location of these rocks in the Arctic realm at various times prior to Cretaceous opening of the Canada Basin.<\/p>\n\n\n\n<p><span style=\"color: #333399\"><strong><em>Pioneer Metamorphic core Complex, south-central Idaho\u00a0<\/em><\/strong><\/span><\/p>\n\n\n\n\n\n<p><span style=\"color: #333399\"><strong><em><a href=\"http:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_5282.jpg\" rel=\"attachment wp-att-207\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-207 alignright\" src=\"http:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_5282-300x164.jpg\" alt=\"\" width=\"300\" height=\"164\" srcset=\"https:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_5282-300x164.jpg 300w, https:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_5282-768x420.jpg 768w, https:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_5282-1024x561.jpg 1024w, https:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_5282-200x109.jpg 200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><\/em><\/strong><\/span>The overarching goal of this project is to decipher the deformational history of the footwall of the core complex.

This type of decoupled flow is depicted in many models for core complex formation, yet the process and resulting features remains poorly documented. This work involves detailed field mapping and structural analysis of the lineation transition zone, as well as establishing the timing of strain at the two levels by dating deformed and undeformed dikes that are widespread. We are also documenting P-T histories of the rocks across the transition zone to establish the vertical motions and conditions of decoupling via metamorphic.<a href=\"http:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_3246.jpg\" rel=\"attachment wp-att-239\"><img loading=\"lazy\" decoding=\"async\" class=\"size-medium wp-image-239 alignright\" src=\"http:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_3246-300x225.jpg\" alt=\"\" width=\"300\" height=\"225\" srcset=\"https:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_3246-300x225.jpg 300w, https:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_3246-768x576.jpg 768w, https:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_3246-1024x768.jpg 1024w, https:\/\/people.clas.ufl.edu\/jvogl\/files\/IMG_3246-200x150.jpg 200w\" sizes=\"auto, (max-width: 300px) 100vw, 300px\" \/><\/a><br>\n(2) Establish the timing and controls of strain localization across all levels of the footwall.
