• The geological and geomorphological studies in Los Covachos cave reveal a wide collection of speleothems and a thick archaeological stratigraphies. Both isotopie dating of speleothems C^ThP^U) and charcoal layers C4C), in chemical and terrigenous sediments, show a Quaternary sequence of palaeoenvironmental evolution related with an alternating phases of biostatic and rhexistatic genesis. The first ones are partially situated in a warm and wet isotopie stages (7, 5, 3, and 1) and the others in a wider warm and dry stages (6, 4 and 2)
