Periglacial microjointing and faulting in Weichselian fluvio‐aeolian deposits
Abstract A Weichselian Late Pleniglacial fluvio‐aeolian deposit has been investigated in the southern Netherlands. Three main structural lineaments have been distinguished: (1) very small, vertical platy structures (microjoints), in a parallel and a columnar configuration; (2) large joints and norma...
