Special Issue Information

Dear Colleagues,

"Past is the key to the future".

Understanding the evolution of volcanic zones in different tectonic environments is important for establishing risk mitigation policies that help to reduce potential damage from volcanic eruptions and lifecycles. During their life cycle, volcanic structures (e.g., stratovolcanoes, calderas, domes) can modify their (i) plumbing systems, (ii) magmatic processes, (iii) magmatic stagnation time, (iv) eruptive styles, and (v) stability, as examples, which may impact the local environment and human population. The volcanic products emitted during eruptions provide useful insights on these processes, making detailed petrography and bulk and mineral geochemistry useful tools for determining the factors which control them. Moreover, active or quiescent volcanic edifices are often associated with hydrothermal systems that can have high geothermal potential that, when exploited, can contribute to the energy transition, helping to reduce carbon emissions due to fossil fuel-related energy.

The objective of this Special Issue, entitled "Magmatic Evolution through Time of Volcanic Zones: Evidence from Isotopic, Geochemical and Geochronological Data of Eruption Products", is to invite contributions that are related to unravelling the evolution of volcanic zones, thus helping to understand the behavior of volcanic systems during their lifetime, as well as contributions to geothermal systems. Therefore, contributions are welcome related to, but not limited to, the following topics:

  • Geochronological evolution of volcanic systems;
  • Magmatic processes occurring during eruptive cycles of volcanic systems;
  • Location and evolution of plumbing system of volcanic edifices;
  • Timescales of magmatic input/interactions;
  • Changes in eruptive styles of volcanic systems;
  • Heat source assessment and heat flux modeling;
  • Hydrothermal fluids and mineralogical alteration in volcanic systems.

This Special Issue aims to broaden our understanding of how different volcanic zones have varied with time. In turn, this will help society to be better prepared for future volcanic activity in the studied areas.

Precise dating of prehistoric volcanic eruptions is essential for reconstructing eruption sequences and assessing volcanic hazards. The timing of the onset and termination of volcanic activity in the Xilinhot volcanic field (XVF) has been a topic of debate for years. Volcanic eruptions in this area began during the Pliocene, with the K-Ar (Ar-Ar) method providing reliable ages for early formed volcanic rocks; however, this method is less effective for dating younger volcanic events that occurred since the Late Pleistocene. For younger volcanoes, sediments baked by volcanic materials, organic sediments, and silty mudstones entrapped in lava serve as excellent geological carriers for dating. In this study, suitable samples collected from the XVF were dated using 14C and optically stimulated luminescence (OSL) methods. The 14C ages obtained for the Gezishan volcano are ~6.8 cal. ka BP, while its OSL age is ~7.8 ka. The ages dated by these two methods, combined with volcano–sedimentary stratigraphic relationships and volcanic topography, confirm the Holocene eruptions of the Gezishan volcano, categorizing it as a broadly active volcano. The upper boundary age of the sandy loam layer beneath the Gezishan lava flow is ~15.5 ka, indicating that the south lava of the Gezishan effusion occurred later than the late stage of the Late Pleistocene. Additionally, the OSL ages of baked sediments at the bottom of the base surge deposits from a Maar-type volcano and aeolian sand interlayers within a Strombolian-type scoria cone in the study area are ~50 ka and ~60 ka, respectively, representing eruptions in the middle Late Pleistocene. These findings demonstrate that volcanic activity in the XVF remained vigorous during the Late Pleistocene to Holocene. This study provides significant insights for reconstructing the evolutionary history of Xilinhot volcanic activity and assessing regional volcanic hazards. Full article
