Stress deviations aren't just for major faults! Caldeira et al. (CH) show #sub-seismic fault zones (<10 km) cause #paleostress rotations up to 30° in the Swiss Jura Mountains

folded prismatic amphibole crystal
Sometimes even the most 'static' rocks show evidence of deformation. This prismatic amphibole crystal is slightly bent and crosscut by a series of cracks that appear related to the bending

Flow banding (Volcanology 🌋)
Flow banding is a geological term to describe bands or layers that can sometimes be seen in rock that formed from magma. Flow banding is caused by friction of the viscous magma that is in contact with a solid rock interface […]
