The diameter is generally greater than 4 millimeters, and the lava fragments contained are mostly tuff, with fewer glass fragments and whole stones. It is mainly composed of volcanic breccia with a particle size of 2-64 millimeters, and also contains breccia from other rocks and a small amount of mineral crystal fragments such as quartz and feldspar.
