Transverse Ranges Geology
Transverse Ranges Alchetron The Free Social Encyclopedia Components of transverse ranges to the north and east of the fault include the san bernardino mountains, little san bernardino mountains, pinto and eagle mountains. the western and southern boundaries are acknowledged to be the pacific ocean and the northern channel islands. The transverse ranges are a distinctive mountain chain in california, characterized by their unusual east west orientation, which contrasts with the typical north south alignment of other geological structures in the state.
Transverse Ranges Alchetron The Free Social Encyclopedia This page covers the geological evolution and processes of the transverse ranges province and san bernardino mountains, detailing the transition from a mesozoic subduction zone to a present day …. In the heart of southern california, a remarkable geological phenomenon unfolds across the landscape—mountain ranges that dare to run east to west instead of following california’s typical northwest southeast mountain alignment. Using fault related folding methods, we predicted the geometry and sense of slip of the major faults at depth, and we used these structures to model the evolution of the western transverse ranges since the late pliocene. the model predictions are in good agreement with the observed geology. Since portions of the captured farallon underlay north america, this change in the direction of plate motion caused several blocks of continental crust to break off, including the transverse ranges block and the outer continental borderland.

While there is no conclusive evidence for a broad north south phylogeographic divide in california based on the transverse ranges, there is evidence for evolutionary divergence within the transverse ranges based on the three geographic regions: the eastern, central, and western transverse ranges. The transverse ranges are caught in a geological vise that has been squeezing them for the past 20 million years, from south to north producing high amplitude compressed folds and faults. the troughs of the folds became deep marine basins and the peaks are expressed as the ranges. This page reviews the geology of the transverse ranges, focusing on significant features such as the san andreas and san gabriel faults. it highlights proterozoic and mesozoic rock formations, including unique anorthosite complexes and pelona schist, indicative of regional geological processes. Rocks of the transverse ranges exhibit extreme differences in geologic age and composition, varying from sedimentary rocks in the western santa ynez and volcanic rocks in the santa monica mountains to primarily granitic and metamorphic rock in the central and eastern segments, including the san gabriel and san bernardino mountains.
