A calcitic crystalloblastic lithotype that is heterogeneous due to the presence of calcitic dominions composed of crystals of different sizes that are subhedral with mainly curved grain boundaries. The calcite is in blasts of a maximum size of 0,6mm. The veins of calcitic microcrystals are particularly convoluted and deformed, alternating with slender layers composed of coarser blasts. Where the veins are located, there are twinned feldspars-albite and new formation quartz that are isooriented and opaque minerals that are widespread in places as microgranulations too.
