Can you help with using Universal stage for potentially shocked quartz?

03 March 2021 0 8K Report

Universal-stage experts: some advice please. I am analyzing a quartz grain with an apparent single set of lamellae. They are not parallel to the c-axis, based on crossed polars. How does one measure the angle of the lamellae relative to the c-axis when there are no 0001 lamellae along the c-axis?
