The brecciation often leaves angular lines of jasper cut across the stone. The most common form is red or yellow jasper cemented with grey chalcedony, but there are many other color variations. Brecciated jasper is jasper that has been broken up internally and cemented together with chalcedony. Some of the most notable deposits are sourced from Australia, Brazil, Canada, Egypt, India, Indonesia, Kazakhstan, Madagascar, Mexico, Russia, Uruguay, Venezuela and the United States of America, including Arizona, Arkansas, California, Idaho, Oregon, Texas and Washington. Sometimes chalcedony and macrocrystalline quartz of different colors fills the voids in the shattered rock. Tectonic activity can go on for a long time, the cracks can reopen again, the jasper can be shattered, and the voids in between the shattered rock can be healed by being filled with more jasper or other material. The cracks in volcanic rocks filled out by jasper often form during tectonic (earthquake and movement) activity. Jasper is typically found in veins and cracks in volcanic rocks, often together with chalcedony and agate. Jasper is typically about 80% quartz (silicon dioxide) and 20% other materials.
