Description :
Erratic boulders of glacial origin, mainly made of jasper, marble and cherty limestone, are found in the main valleys of the Apuan Alps. Such boulders are especially widespread in the north-eastern sector of the Apuan Alps, sometimes in great number, and they bear witness to a 6 km long journey. The types and distribution of the erratic boulders allow one to outline the dimensions of the main glacial bodies and assess the relationships between them. Moreover, the presence of erratic boulders opens new avenues of research in order to complete the description of the Apuan glaciation and its chronology by using the techniques of exposure age dating, which can be easily applied to erratic boulders. - (NFà.
