The Menderes Massif exposing in the Western Anatolia substantially presents a complex tectonostratigraphy as a result of Late Alpine compressional tectonism. The lithostratigraphical succession of this crystalline complex can be divided into two units: 1- The Pan-African basement (core series) and 2-Palaeozoic - Early Tertiary metasedimentary rocks (cover series). The Pan-African basement of the Menderes Massif is made up of a Late Neoproterozoic metaclastic sequence consisting of paragneisses and conformably overlying micaschists. This high-grade metaclastic sequence is extensively migmatized and intruded by the syn- to post-PanAfrican gabbros and granitoids. The primary contact relationship between the core and cover series is …

The Funeral Mountains of Death Valley National Park, CA, provide an opportunity to date metamorphism resulting from crustal shortening and subsequent episodic extensional events in the Sevier hinterland. It was not clear whether crustal shortening and thus peak temperature metamorphism in the hinterland of the Sevier-Laramide orogenic wedge have occurred whether in Late Jurassic, Early Cretaceous , Late Cretaceous or somewhere between. Particularly ambiguous is the timing of crustal shortening in the deep levels of the hinterland of the Sevier belt, now manifest in the metamorphic core complexes, and how and when these middle-to-lower crustal rocks were exhumed. A 6-point …

Bedrock Geology And Tectonic Evolution Of The Western Central Maine Zone, South Central Massachusetts, Thomas Bradley Walker
Theses and Dissertations--Earth and Environmental Sciences
Bedrock geology of the East Brookfield quadrangle (EBQ), based on new 1:24000 scale mapping, consists of an interfolded sequence of Rangeley Fm. and Paxton Fm. metasediments, intruded by Early Mississippian tonalitic to granitic orthogneisses and underlain in the western half by folded orthogneisses of unknown age. Pervasive flattening strains have created planar, generally NNE-SSW striking and consistent moderately west dipping foliations. Generally strike-parallel stretching lineations and boudinage structures, with rarer dip parallel stretching lineations, reflect extrusion of CMZ metasediments and orthogneisses with a flattening component. Mapping in the EBQ demonstrates that a transition between deformational mechanisms of the southern Central …
