Phyllite is an intermediate-grade metamorphic rock Phyllite resembles its protolith, shale, as well as its lower-grade counterpart, slate Phyllite can be distinguished from shale by its brittleness and foliation slaty cleavage Unlike slate, phyllite shows a contorted foliation and glossy sheen Phyllite lacks the higher graded minerals and ....
Aug 20, 2019 0183 32 La pizarra es una roca metamórfica con un brillo opaco El color más común de la pizarra es el gris, pero también puede ser marrón, verde, violeta o azul La pizarra se forma cuando se comprime una roca sedimentaria lutita, lutita o basalto Con el tiempo, la pizarra puede pasar a otras rocas metamórficas, como filita o esquisto Es probable que haya encontrado pizarra en un edificio o ....
