DTM-Based Morphometric Analysis of Scoria Cones of the Chaîne des Puys (France)—The Classic and a New Approach

Scoria cones are favorite targets of morphometric research. However, in-depth, DTM-based studies have appeared only recently, and new methods being developed. This study provides a classic evaluation the Chaîne des Puys (Auvergne, France) as well introduces more detailed statistics-based set properties. Beside parameters, sectorial approach is applied to slope distributions calculated from high resolution DTMs for 25 different lithologies, in order various (a)symmetries cones. characteristics been found be descriptors, whereas describes correctly less regular shapes. The distribution interquartile ranges skewed. Sectorization discriminates types symmetries: there almost circular cones, but majority elongated some asymmetry. relationship between size parameters reflects lithology, rather than age cone. attempt relate data partially successful: although certain trend, within same lithological group, subtle possibly systematic trends can detected decreasing values (e.g., slope) with age. regression models indicate outcomes. Further work needed understand all diverse especially lithology–shape relationship, how symmetry connected factors.
