Structural Analysis


 

Our structural research is aimed at characterizing microscopic to macroscopic deformational features, interpreting their kinematic significance, and relating their development to larger-scale tectonic processes, especially in arc-related environments.

Most of this work takes place in high-grade metamorphic or igneous terrains and involves the analysis of both regionally distributed tectonite fabrics and mylonitic fabrics in shear zones. Pre-, syn-, and post-kinematic plutonic rocks have permitted us to constrain the duration of deformational events and the rate of change of structural styles. An example is the Mid-crustal exposure of arc rocks in the Santa Lucia Mountains (California) where U-Pb zircon dating of orthogneisses and undeformed plutons bracket the time of ductile deformation in the Cretaceous California arc.
