Collaborative Research: The Tectonothermal Evolution Of A Convergent Orogen, Scott E. Johnson Nov 2006

Collaborative Research: The Tectonothermal Evolution Of A Convergent Orogen, Scott E. Johnson

University of Maine Office of Research Administration: Grant Reports

Understanding of orogenesis and its relations to mantle convection and plate tectonics relies on integrated studies of the interrelations among processes of deformation, metamorphism and magmatism. A well preserved portion of the northern Appalachian orogen is providing an outstanding laboratory for a truly integrative study of the evolution of mid-crustal processes that strongly influence orogenesis. This project is employing structural, microstructural, petrologic and thermobarometric analyses, and chemical and isotopic dating, to temporally and spatially link deformation, metamorphism and magmatism during the progressive growth of this orogenic belt. This information is being used to set constraints and boundary conditions on coupled, …

It is poorly known if fault slip repeats regularly through many earthquake cycles. Well‐documented measurements of successive slips rarely span more than three earthquake cycles. In this paper, we present evidence of six sequential offsets across the San Andreas fault at a site in the Carrizo Plain, using stream channels as piercing lines. We opened a latticework of trenches across the offset channels on both sides of the fault to expose their subsurface stratigraphy. We can correlate the channels across the fault on the basis of their elevations, shapes, stratigraphy, and ages. The three‐dimensional excavations allow us to locate accurately …
