Mesocratic natural stone, with gray tonality, containing dispersed black crystals of centimetric dimension and of holocrystalline and massive form. It presents granular, phaneritic texture, from fine to coarse grain. The constituent minerals generally present grains with an anhedral to subhedral shape and some with a prismatic tendency, without lineations, cracks, pores or cavities. The rock does not present any type of orientation, foliation, shale or apparent tectonic deformation.
It is a basic natural stone of intrusive igneous (plutonic) origin, composed mainly of non-equidimensional grains of plagioclase and pyroxene.
The natural stone has a holocrystalline, phaneritic, non-equigranular texture, of medium to coarse grain, with a hipidiomorphic tendency.
Ortopyroxenes (5%), occurring with an antheric or prismatic habit. Clinopyroxenes (3%), occurring with anhedral to subferric habit, sometimes presenting alteration aureoles. Plagioclase (90%) in crystals with a subhedral or prismatic subidiomorphic habit, with hydrolysis phenomena, which promote its alteration.
Biotite (2%) and opaque (<1%) disseminated by the mass of the sample.
Clay minerals (2%) occurring in the nucleus of altered plagioclase and disseminated iron oxides.
