Abstract
The chronology of the maximum ice extent during the Last Glacial Cycle has been a subject of intense debate within the Iberian glacial geomorphologists community. Until the last decades of the 20th century, the use of radiocarbon dating suggested that the Local Last Glacial Maximum (LLGM) occurred in Iberian Mountains at c. 50–40cal ka BP, or before. More recently, the chronology of the LLGM has been reconsidered thanks to the widespread use of other dating techniques, namely, optically stimulated luminescence and cosmic-ray exposure dating. In most massifs the LLGM took place during the Global Last Glacial Maximum (GLGM), and in others LLGM glaciers were only slightly larger than the GLGM expansion and left smaller moraine complexes than the larger GLGM moraines.
