Abstract

The aim of this study is to analyze the dynamics of rock glaciers located in temperate mountains with periglacial high mountain in discontinuous permafrost environments and their possible use as environmental geoindicators. The AA. present the results of a study of the surface displacement of the Posets rock glacier from 2001 to 2008. Horizontal and vertical displacement rates in different sectors of the rock glacier were compared, and these compared with thermal, structural and morphological maps. The inferred surface deformation was characterized by extensional and compressive flows in which 2 dynamic types were found : 1) slide and flows related to the existence of an ice body over the frost body ; 2) displacement generated by deformation of the frozen body
