Es asi como el 'Batolito de El Carmen' presenta niveles de inestabilidad critica (Cuadro 8), observandose moderados a espesos perfiles de meteorizacion, en sitios donde los niveles de alteracion corresponden a las etapas: nucleos de roca (corestone), granitoide descompuesto y saprolito, propuestas por Durgin (1977); donde se destaca un alto grado de fracturacion caracterizado por la presencia de 4 familias principales de diaclasas mas otras ocasionales, cuyas orientaciones en algunos casos son favorables a la generacion de movimientos de masa (a favor de la vertiente), con espaciados catalogados como juntos a moderadamente juntos, segun los rangos propuestos por la ISRM (1981; en Gonzalez de Vallejo et al., 2002), y aberturas de diaclasas anchas a extremadamente anchas (1- >20 cm).

Corestone boulders and many bornhardts are etch or two-stage forms that were initiated by differential weathering at the weathering front by waters penetrating from fractures into the fracture-defined blocks (figure 4).

Depending on the degree of weathering, the decomposed granite layer was classified into four categories as moderately (MDG), highly (HDG), completely decomposed granite (CDG), and partially existing corestones, where MDG, HDG, and CDG could be classified very hard to hard rock, highly fractured normal to weak rock, and very weak rock to weathered soil, respectively.
