Santa Maria d’Anglona: inquadramento geologico e geomorfologico
Abstract
The Santa Maria D’Anglona site is geologically located in the central-western part of the Bradanic Trough, on a marine
terrace outcropping at an altitude between 277m and 245m a.s.l. It consists of flat pebbles of a polygenic nature, up to
10cm in size, immersed in a reddish sandy matrix. Stratigraphically below the terraced marine deposits, there are blue
grey clays and marly-silty clays with a indistinct stratification containing intercalated havana silty sand levels, belonging
to the quaternary Subapennine Clay Formation, with a total thickness range of 800 to1000 meters. The Bradanic Trough is a Pliocene and Pleistocene sedimentary basin that developed between the Apennines Foredeep and the Apulian Foreland with several deformative phases during the Pliocene and early Pleistocene. The Santa Maria D’Anglona area, due to the lithostratigraphic characteristics, the structural conditions of the subapennine clays and rainfall erosion,
is characterized by the presence of suggestive, widespread badlands (calanchi and biancane) that develop largely along the hilly clayey slopes of the Subapennine Clay Formation.
