Pelona Schist Usamapxl The pelona schist in the san gabriel mountains, southern california, formed in the laramide subduction channel, exhibits multiple phases of deformation metamorphism and provides valuable. The pelona, orocopia, and rand schists and the schists of portal ridge and sierra de salinas constitute a high pressure temperature terrane that was accreted beneath north american basement in late cretaceous earliest tertiary time.
Tectonic Model Of The Pelona Schist A The Pelona Schist Was The pelona schist in the san gabriel mountains, southern california, formed in the laramide subduction channel, exhibits multiple phases of deformation metamorphism and provides valuable insights into the rheological properties of the subduction channel. The pelona–orocopia–rand and related schists of southern california are an archetypal example of an exhumed shallow subduction complex. ‘the schist’ comprises mainly trench materials underthust beneath continental arc rocks during late cretaceous–early cenozoic collision of one or more oceanic plateaux with southern california. To illustrate the heterogeneity in mechanical properties, we focus on samples from sierra pelona, portal ridge, and rand mountain, here referred to as pelona schist, portal schist, and rand schist, capturing different relevant protoliths and metamorphic grades. The pelona schist consists of oceanic rocks that were metamorphosed during late cretaceous early tertiary time in a subduction zone, later to be called the vincent thrust fault, that since has been exhumed (jacobson et al., 1996).

The pelona–orocopia–rand (por) schist and related schists in the southwestern united states are considered the world's best known example of an ancient shallow subduction complex. they were formed during the laramide orogeny and are associated with the subduction of oceanic plateaux. This study tests the viability of the flat slab model against alternative hypotheses, including the collision and translation of a far traveled terrane, through detailed study of the pelona orocopia rand schist. Abstract the pelona, orocopia, and rand schists and the schists of portal ridge and sierra de salinas constitute a high pressure temperature terrane that was accreted beneath north american basement in late cretaceous earliest tertiary time. Pelona schist underlying portal and ritter ridges. the early fabric of the schist is modified and in places obliterated by cataclasis along shear zones near the san andreas fault and the hitchbrook fault, a major west striking branch of the san andreas fault system.
