Fission-track analysis of samples from the Alboran Sea basement
Hurford, A.J. and Platt, J.P. and Carter, Andrew (1999) Fission-track analysis of samples from the Alboran Sea basement. Scientific Results 161 , pp. 295-300. ISSN 1096-7451.
Abstract
Fission-track analysis was used to examine 13 basement samples of high-grade schist, pelitic gneiss, granite, migmatite, and calc-silicate rock, obtained from Ocean Drilling Program Hole 976B in the floor of the Alboran Sea. Long mean-track-length and tight length distributions, together with homogeneity of apatite age, indicate rapid cooling through the temperature range from 120° to 60°C at about 18-19 Ma. This cooling history represents exhumation within the top few kilometers of the earth's surface, and is therefore likely to date the creation of the present basement morphology in the area. The cooling age is very close to the age of the oldest sediments in the Alboran Sea, which indicates a close link in time between basement exhumation and creation of the Alboran Sea basin.
