Block and slab characteristics
Average size of blocks: 3,00 x 1,70 x 1,70m.
Slabs are prefarably cut against the grain or perpendicular to the grain, i.e. the hard way and the easy way.

Microscopic description according to EN 12407 e EN 12460
| An isotropic metamorphic lithotype (that is anisotropic where the veins occur) composed of subeuhedral/euhedral calcitic granules with straight/sutured grain boundaries that are interlobed in places. The grain size is seriate from 60 to 700 µm, in contrast with areas of an average size of 200 µm and areas of an average size of 650 µm. There is also rare straight layering, composed of calcitic blasts varying in size between 60 and 150 µm, opaque minerals (pyrite and micrometric magnetite) and iso-oriented acicular muscovite following the orientation of the veins. The same mineral phases may be spread throughout the crystalloblastic mosaic with trace amounts of quartz |
