Congrats Kyle!

Kyle Bogatz recently defended his Master’s Thesis titled, “Deformation of brittle clasts within a viscous matrix: field and experimental observations.” Kyle leaves us after many years, first as an undergraduate researcher and followed that up with his Master’s work. Kyle’s project combined field work at the Papoose Flat Pluton in California and some preliminary lab … Continue reading Congrats Kyle!

New paper in press!

The Structure Lab has a new paper in press titled The effect of a liquid phase on force distribution during deformation in a granular system. Look for it in the Journal of Geophysical Research – Solid Earth. https://agupubs.onlinelibrary.wiley.com/doi/abs/10.1029/2020JB019771 Abstract Two‐phase systems, where one phase is solid and the other fluid, are widespread in nature. Examples … Continue reading New paper in press!

Ring shear device up and running!

Nearly 2 years after its conception, the Structure Lab’s ring shear device is up and running. The soothing green glow is from a laser sheet illuminating brittle polymer spheres surrounded by viscous gel. Kyle Bogatz is conducting experiments on processes of grain fracturing in semi-brittle material (picture feldspar clasts in a semi-brittle granitoid). This represents … Continue reading Ring shear device up and running!
