From: Modeling fracture cementation processes in calcite limestone: a phase-field study
Natural samples of calcite veins in Jurassic limestones from southern England exhibiting a fibrous, b elongate-blocky, c partially open, and d euhedral morphologies. The wall rock in fibrous veins is not contained in the sample, but is located towards the base of the image in a. Different interference colors of vein crystals depict different crystallographic orientations. All images are obtained from transmitted microscopy and crossed polarizers
