Abstract
PIXE elemental analysis of sediments, speleothems, and other geological for mations related to the karst of the Sierra de San Carlos is presented, The similarity of the elemental composition of the sediments studied, as well a s the alluvial regime which created them, indicate their common origin at e ach location, The Sr/Ca concentration ratio of a stalactite indicates that the average atmospheric temperature 12,000 and 18,000 years B.P, was colder than that of 6000 years B.P, (C) 2000 Elsevier Science Ltd.
