Procesos degradativos en antiguas superficies grabadas sobre granitos: Indicadores de magnitud y patrones de estado

This paper analyzes the so called, (pilas, gnammas, vasque, etc.), small concavities that retain the water of the rain/ runoff that develops etching processes. Some authors support the beginning of the form already undersoil/ regolith, though all recognize the main development of the form in subaeri...
