Interpreting Compositional Variations in the Stratigraphic Sequences of Small-Scale Basaltic Volcanoes
A notable feature of small monogenetic volcanic cones is their systematic compositional variations. These variations are typically closely correlated with their stratigraphy and record changes in the composition of magma erupted at the Earths surface as an eruption progresses. Generally, the compositional trends are from relatively evolved magmas in the initial stages of an eruption to relatively primitive toward the end. However, recent studies have revealed several other variation patterns indicating the operation of several processes. One of the reasons that these patterns are observed is that the magmas of monogenetic volcanoes are generally of small volume and they rise rapidly from their source without significant interaction with the crust.
