One of the most common locations for breccia formation is at the base of an outcrop where mechanical weathering debris accumulates. Another is in stream deposits a short distance from the outcrop or on an alluvial fan. Some breccias form from debris flow deposits.Sulfur has double refraction (0.291), which is twice higher than that of calcite. However, double refraction of sulfur is rarely discussed as it hardly ever form transparent crystals big enough to observe double refraction. Also, sulfur is easy to identify by other properties like color and hardness.
