Classical statistical techniques for deciphering the origin and evolution of volcanoes at volcanic front of the central part of the Mexican Volcanic Belt

Abstract

New geochemical data for the Sierra de Las Cruces are combined with the published data from this volcanic range and the Sierra de Chichinautzin. Both Neogene-Quaternary ranges are located at the volcanic front of the central part of the Mexican Volcanic Belt (MVB). These geochemical data were statistically evaluated to establish central tendency and dispersion estimates for different magma types from basic to acid, which were compared with worldwide arcs and rifts. UDASYS software was used for this purpose. Similarly, multi-dimensional diagrams recently proposed (2006-2013) were also applied to decipher the tectonic setting. These statistical techniques provide further constraints on the origin of the MVB.
