MICROSCOPIC DESCRIPTION (ACCORDING TO EN 12407 AND EN 12670)

A CALCITIC CRYSTALLOBLASTIC LITHOTYPE COMPOSED OF DOMINIONS OF HETEROGENEOUS SIZES AND MICROTEXTURES. SUBHEDRAL CRYSTALS WITH STRAIGHT OR CURVED GRAIN BOUNDARIES ARE PRESENT WITH MICROTEXTURES THAT ARE DIFFERENT IN PLACES. THE BLASTS ARE GENERALLY < 0,1MM, EVEN IF LARGER PORPHYROBLASTS MAY ALSO BE PRESENT. SOME VEINS ARE GENERATED BY THE ALIGNMENT OF THE BLASTS THAT ARE LARGER THAN THE SURROUNDING ONES, WHILE OTHERS ARE COMPOSED OF CALCITIC MICROBLASTS (PROBABLY MICRITIC RELICTS) THAT ARE VERY DEFORMED AND CONVOLUTED. THE MICROCRYSTALS IN THESE AREAS ARE ASSOCIATED TO MICROGRANULATIONS OF OPAQUE MINERALS, RUTILE, ACICULAR MUSCOVITE AND SLIGHT MUSCOVITE AGGREGATES.

THE REFERENCE SAMPLE DOES NOT IMPLY STRICT UNIFORMITY BETWEEN THE SAMPLE ITSELF AND THE ACTUAL MATERIAL; NATURAL VARIATIONS MAY ALWAYS OCCUR. ALTHOUGH ALL EFFORTS HAVE BEEN MADE TO REPRODUCE THE EXACT LIKENESS OF THE MATERIALS, THERE MAY BE SLIGHT DIFFERENCES DUE TO THE PRINTING PROCESS. THE TECHNICAL INFORMATION FOR THE MATERIALS IS BASED ON TESTS CARRIED OUT AT THE MARBLE LABORATORY OF THE POLITECNICO DI TORINO DIPARTIMENTO DI INGEGNERIA DEL TERRITORIO, DELL'AMBIENTE E DELLE GEOTECNOLOGIE AND PROVIDES A REFERENCE FOR THEIR CHARACTERISTICS. NATURAL STONE MATERIALS ARE HOWEVER NATURAL PRODUCTS AND AS SUCH ARE SUBJECT TO VARIATIONS. HENCE IT IS GOOD PRACTICE TO TEST THE MATERIALS EACH TIME THEIR SPECIFIC PHYSICAL-MECHANICAL PROPERTIES ARE REQUIRED.
