Melanocratic rock, dark gray in color, containing scattered black crystals of centimeter dimension. It stands out for its granular, phaneritic texture of fine to medium grain. The constituent minerals generally have grains with anhedric to subhedric shape and some with prismatic tendency, without lineations, cracks, pores or cavities. The rock shows no orientation, foliation, schist or apparent tectonic deformation.
This is a basic rock of intrusive (plutonic) igneous origin, composed mainly of non-dimensional pyroxene and plagioclase grains.
The rock has a holocrystalline, phaneritic, non-equigranular texture of medium to coarse grain, with a hypidiomorphic tendency.
Ortopiroxenas (40%), occurring with anhedric or prismatic habit. Clinopyroxenas (20%), occurring with anhedric to subhedric habit, sometimes presenting alteration halos. Plagioclase (35%) in crystals with subedric or subidiomorphic prismatic habit, with hydrolysis phenomena, which promote its alteration.
Olivine (3%) and opaque (<1%) disseminated by sample mass.
Clay minerals (3%) that occur in the nucleus of altered plagioclases and disseminated iron oxides.
