“…We sampled tephra material according to two assumptions within the EEVF and WEVF: (i) the edifice size correlates with distance of tephra distribution, as areal distribution correlates to eruptive volume (Pyle, 1989;Fierstein and Nathenson, 1992) and each voluminous monogenetic eruption produces a large vent (Kereszturi et al, 2013;Blaikie et al, 2015); and (ii) youngest tephra layers must be linked with the youngest eruption centers of the entire volcanic fields. Within the EEVF, Wingertsberg and Eppelsberg are two scoria cones situated close to the LSV (Schmincke, 2007(Schmincke, , 2014, which were sampled for clinopyroxenes and compared to the ET.…”

“…These prominent tephra layers must have been erupted by the largest volcanoes of the Eifel Volcanic Fields, as generally the area of tephra distribution correlates to the volume of a volcanic eruption (Pyle, 1989;Fierstein and Nathenson, 1992;Pyle et al, 2006). As all Eifel volcanoes are monogenetic, each of these voluminous eruptions would have produced a large vent (Kereszturi et al, 2013;Blaikie et al, 2015). However, only the LST has yet been correlated to its source within the EEVF.…”

“…The total amount of magma erupted as ash, scoria and lava flows by the EEVF was estimated to be about 15 km 3 and for the WEVF about 1.7 km 3 (Schmincke, ). The amount of magma supplied to the surface was probably higher because the calculations by Schmincke () do not account for shallow sub‐volcanic intrusions that are common within the diatremes of maar volcanoes (Kereszturi et al , ; Blaikie et al , ).…”

The Eifel Laminated Sediment Archive (ELSA), which comprises several cores from maar lakes, includes numerous tephra layers spanning the last 140 000 years. The sediment cores are dated by 14C and thermoluminescence as well as tuned to Greenland stadial–interstadial successions. Within the last glacial cycle, the Eifel Volcanic Fields are source to several widespread tephra layers, namely the Laacher See, Eltville, Rambach and Rocourt Tephra. However, a corresponding source volcano was so far only identified for the Laacher See Tephra. In this study we use glass and clinopyroxene geochemistry to link the remaining tephra layers to possible eruption centers within the West and East Eifel Volcanic Fields: while we demonstrate that the Eltville Tephra originated from an earlier eruption of the Laacher See Volcano at 24 300 a bp from within the East Eifel Volcanic Field, the Rambach and Rocourt Tephras are sourced from the West Eifel Volcanic Field and erupted from Wartgesberg at 27 900 a bp and Pulvermaar at 75 000 a bp, respectively. Phases of volcanic activity peaked at 10 000–30 000 and 60 000–80 000 a bp and were thus erupted around the temperature minima of the last glacial cycle. The longest phase of dormancy between individual vents was around 30 000 years long, within the last interglacial.

With the advent of new terminologies to categorize and characterize the simple and complex monogenetic volcanoes, also came the semantic issues, which caused a predicament for the usage of terms like simple, complex, polycyclic, polymagmatic, complex monogenetic volcanoes with polygenetic inheritance. To analyse and validate this nomenclature, we studied an overlapping volcanic structure located south of the present‐day town of Irapuato, Central Mexico, that appears to be a monogenetic complex at first sight. Field observations, tephra stratigraphy, petrography and geochemistry of the tephra deposits confirms that the structure is in fact a cluster of three simple (San Joaquin tuff ring and two scoria mounds) and one complex, polycyclic, polymagmatic (La Sanabria‐San Roque tuff ring) monogenetic volcanoes formed by independent events, governed by distinct conduits and magma bodies of different origin (subduction‐related, OIB and E‐MORB origin) and separated by different tephra sequences of dissimilar components and depositional characteristics. We estimate the magma volumes (using the juvenile content and their vesicularity percentage) to be at 0.40–1.31 × 108, 0.25 × 108 and 0.42–0.90 × 108 m3 for San Joaquin, La Sanabria and San Roque, reckoning an eruption duration of 77 and 48 and 81 days, respectively (considering an average eruption rate of 6 m3/s from the well‐documented shallow crater (<30 m), Ukinrek maars in Alaska) occurring within the age range of 40–70 k years (crater diameter and depth ratio). This study not only aided to validate the above‐mentioned terms for monogenetic volcanoes, but also reconsider a few of them and avoid confusion with the polygenetic counterparts.
