Carles Roqué i Pau, Lluís Pallí Buxó
The landforms that appears in granite slabs of the megaliths, that localize in the NW part of Catalonia, had studied far quantify their increase values. The results allow of distinguish between pre and postmegalithical landforms. Sorne premegalithical gnammas are 5000 years old ar more and has developed actually. Had been calculate 1 cm/ 1000 years deepening rates far gnammas and between 0,4 and 3 cm/ 1000 years far the alveoles according to postmegalithical landfarms sizes. The size cannot be used far age approach in another postmegalithical landfarms (pitting, «pseudorejones» and speleothems).
