26 samples are as many species can be found in sacharoid marble. This matrix is considered to be typical of the most metamorphisms in Somma-Vesuvius. It is defined as "saccaroid marble" because it consists of limestone white with the typical granularity of the sugar. Also, hit, emanates odor. Even in this type of projector, very rare species can be found.
