Microscopic appearance of fine CCC from Mörkgletscher. (a) and (b) are optical images of aggregates of euhedral calcite crystals showing a variety of particle shapes. (c) and (d) are SEM images of rafts and spheroids, respectively, both characterized by a conspicuously flat side where these particles touched the ice during growth.
