Rock strain fringes. Polarised light micrograph of strain fringes formed around magnetite crystals (the small black squares) in a phyllite matrix rock. The fibrous quartz in the fringes are formed by shear stresses from when the rock formed. This image has been obtained using cross-polarised light (or 'crossed nichols'),which helps make the strain fringes visible | |
