| 摘 要： | Geology and pedo-stratigraphy of the Ciliverghe hill(glacial deposits,pedogenesis,and loess sedi-mentation along the Alpine fringe during the Pleistocene).-Ciliverghe hill consists of Pleistocene continentaldeposits.The lowest units(CIL 1 and CIL 2).composed of till and related fluvioglacial deposits.representthe oldest moraine ridge of the Garda lake moraine system.These units are covered with angular unconfor-mity,by glacio-lacustrine marls(CIL 3),by fluviatile gravels supplied from a local source(CIL 4)and by flu-vio-glacial gravels(CIL 5)including Central-Alpine rocks.In the upper unit a rubefied,strongly weatheredpalaeosol is developed.At the top of the sequence there is a polygenetic cover of loess consisting of at leastthree distinct layers intercalated with pedogenetic horizons.The uppermost loess which includes mouste-rian artifacts dates back to the Late Pleistocene,Five glacial stages are therefore recorded in the Ciliverghesequence,probably spanning the whole glacial Pleistocene.The stratigraphical and morphological develop-ment of the Ciliverghc hill has been tectonicallv controlled due to the activity of buried tectonic structures.
