Flinn diagram

Quick Reference

A graphical representation of the full range of three-dimensional strain states in deformed rocks, with or without a change in their volume. The diagram plots a value for the principal strain axes Y/Z against X/Y of ellipsoids (see strain ellipsoid) which result from dilation and/or distortion of a reference sphere. The data plotted on the diagram are obtained from analyses of strain using strain markers.
