DTM-Based Comparative Geomorphometric Analysis of Four Scoria Cone Areas—Suggestions for Additional Approaches

Morphometric studies of scoria cones have a long history in research. Their geometry and shape are believed to be related evolution by erosion after their formation, hence the morphometric parameters supposed with age. We analysed 501 four volcanic fields: San Francisco Volcanic Field (Arizona, USA), Chaîne des Puys (France), Sierra Chichinautzin (Mexico), Kula (Turkey). All (cone height, cone width, crater slope angles, ellipticity) were derived using DTMs. As new parameters, we calculated Polar Coordinate Transformed maps, Spatial Elliptical Fourier Descriptors study asymmetries. The age groups fields created distributions analysed. individual show statistically significant decreasing tendency angles tested Mann–Whitney tests. By mixing sorting them interval, can also observe general, decrease. interquartile ranges tend decrease time. These observations support hypothesis that whereas differs initially (just formation), general trends may exist for morphological time various fields.
