Synopsis

Recent excavations at Moss of Cruden, Grampian Region, show that Lower Cretaceous sedimentary rocks pass beneath the margin of the Tertiary Buchan Ridge Gravels and are intensely weathered. These findings indicate that previous interpretations of these rocks as a glacially-transported erratic mass or masses were incorrect and that they are probably in situ. The rocks include fine-grained, glauconitic quartz-arenites with pollen of Late Hauterivian-early Barremian age. Overlying flint gravels demonstrate the presence of a former Cretaceous chalk cover and helped the preservation of this small outlier.
