Structural data, geomorphology and rock slides in the SW of Barles (The Alps of Northern Provence, France)

Abstract

The Alps of northern Provence in France is a familiar area to European geologists because numerous, long field studies have been organized by European universities and private petroleum companies during the 20th century and the beginning of the 21st century. Nevertheless, geologists have made few comments on the consequences of some topographic slides and, more broadly, on the manner by which nature has sculpted the local geomorphology. After having set the local tectonic data (the thrust of the Blayeul Massif on an already folded para-autochtonous formation and locally up and down reversals in the area of the Heights of Chine and Proussier), a geological and geomorphological summary introduces a discussion on slides and slope formations; then the details of the morphology analysis lead us to the conclusions.
