A1 Poupeau, G. A1 Casquet Martín, César A1 Galindo, Carmen A1 González Casado, J. M. AB The principles of Apatite Fission Track Analysis (AFTA), which allows to decipher the time-temperature paths of apatites since their last cooling below about 110°C are given and one example, from a Pedriza - La Cabrera block, is discussed. It is suggested from AFTA that the cooling history of this sample followed three steps: from 45 Ma to 35 Ma, slow cooling at a rate of 2,5 - 5° C/Ma between 110° C and 60° C, followed by a quasi-plateau at 70-80°C up to about 70 Ma ago, where a new cooling episode started, with a mean 6 -7 ° C/Ma cooling rate up to the present time PB Sociedad Geológica de España YR 1995 FD 1995 LK http://hdl.handle.net/10272/13518 UL http://hdl.handle.net/10272/13518 LA spa DS Repositorio Institucional de la Universidad de Huelva RD 16 jul 2026
