SYNOPSISAeolian sandstones of Lower Permian age occur in the centres of faultbounded intermontane basins in the southern Uplands of Scotland. At Locharbriggs, Dumfriesshire, three quarries expose vertical faces up to 20 metres high and 150 metres long in which the aeolian cross-lamination is cut by three different bounding surfaces of different hierarchical order. These surfaces indicate that the aeolian sandstones can be interpreted in terms of dunes climbing over larger bedforms called draas. Analysis of th…
scite is a Brooklyn-based startup that helps researchers better discover and evaluate scientific articles through Smart Citations–citations that display the context of the citation and describe whether the article provides supporting or contrasting evidence. scite is used by researchers from dozens of countries and is funded in part by the National Science Foundation and the National Institute on Drug Abuse of the National Institutes of Health.
