S 1 is axial planar to isoclinal folds, indicating an axial plane cleavage origin.
WebRocks are predominantly steeply dipping and their map-view pattern delineates three bends: the Z-shaped Texas and Coifs Harbour oroclines in the north and the U-shaped Manning Orocline in the south. During the early Permian (298-288 Ma), the area was affected by widespread, mostly S-type, magmatism that heralded a period of crustal extension ... WebSep 15, 2011 · The orocline has an along strike extent of some 600 km and a width of around 350 km. It is defined by the folding of a convergent plate margin assemblage, and developed during the late Paleozoic to early Mesozoic Gondwanide orogeny [ Korsch and Harrington, 1987; Cawood et al., 2011 ].
WebAlternatively, I propose that the Texas Orocline formed through multiple stages, with an initial curved structure that may have resulted from subduction rollback or a pre-existing curvature in the palaeomargin of eastern Australia. This initial curvature was amplified by subsequent contractional deformation. Structural observations were also ...
