A crystalloblastic metamorphic lithotype composed of anisotropic calcite. two different patterns can be observed. the first is anisotropic, composed of calcite blasts that are subeuhedral with straight, rounded/sutured grain boundaries. the mosaic structure is seriate in size between 50 and 250 ¦Ìm. there are trace amounts of quartz crystals and in places plurimetric-sized nodules of a relict appearance made up interlobed, deformed calcite that is clouded by opaque material. veins occur with a sub-parallel orientation composed of calcite blasts and microblasts that are clouded to some extent. these form a second pattern composed of a mosaic of calcite blasts of a maximum size of 500 ¦Ìm with interlobed, de-formed boundaries clouded by opaque minerals that alternate with micrometric blasts (30 m), abundant quartz and trace amounts of feldspar.
