Abstract Details

2022, Master of Science, Miami University, Geology and Environmental Earth Science.
The Trans-Mexican Volcanic Belt is host to several active volcanic fields, within which are clusters of monogenetic volcanoes that erupt in close temporal and spatial proximity to one another. These fields provide a unique opportunity to investigate the petrologic and geochemical evolution associated with monogenetic magmatism at a single location over a well-constrained timeframe. The Holocene Tacámbaro cluster, located in the Michoacán-Guanajuato volcanic field in central Mexico, comprises four monogenetic volcanoes. These centers erupted basaltic andesite to andesite over ~3,300 years, starting with an explosive eruption and evolving to effusive eruptions, with increasing SiO2 and decreasing crystal contents. We have performed petrography, elemental and isotopic analyses, and geochemical modeling of Tacámbaro cluster samples to assess the potential roles of fractional crystallization, crustal assimilation, and mantle source enrichment contributing to their petrogenesis. Major elements are generally consistent with variable degrees of fractional crystallization, but trace elements and isotopes are indicative of mantle source enrichment. The temporal-compositional variations are interpreted to derive from multiple melts of a heterogeneous, slab fluid-enriched mantle source, which undergo variable crustal storage and extents of fractional crystallization.
