Flame structures in metasedimentary rocks bounding the Sierra Nevada batholith, Cascade lake segment:
A deformed tension gash in metavolcanic rocks of the Gem Lake segment of the Sierra Crest shear zone:
Some kink bands in metavolcanic rocks of the Gem Lake segment of the Sierra Crest shear zone, including a kinematic interpretation:
A crazy idea I had while working on the Sierras: two-phase subduction on Mesozoic west coast, giving rise to two generations of Sierran plutons. I no longer think this is the case, but I I like the color balance of the illustration, so I'm leaving it up here as a visual example without any real scientific validity:
Another (possibly correct) idea that emerged from my thesis is how shear zones might allow emplacement of voluminous granitoid plutons. This offers a solution to the "room problem" of how fat bodies of granite get emplaced in an overall convergent tectonic setting (with massive compressive stress):
Monoclinic vs. triclinic transpression models (the modeling part of my master's thesis).
What this means for lineation in metamorphic rocks in the monoclinic situation:
I used CorelDraw to create all these images. If you are interested in commissioning
