Abstract

There is a need for terminology to describe crystallization textures and fabrics in sedimentary rocks. At present such terms are borrowed from igneous and metamorphic petrology with resultant confusion and inconsistencies. The terms xenotopic, hypidiotopic, and idiotopic are proposed for crystallization fabric for both inequigranular and granular fabrics. The terms porphyrotopic and poikilotopic describe inequigranular fabrics. The terms anhedral, subhedral, and euhedral are recommended for more extensive usage in describing carbonate texture.
