New Views on Submarine and Terrestrial Intra Plate Volcanism
Session ID#: 251106
Session Description:
Intra plate magmatism is an enigmatic process responsible for a variety of volcanic structures across the continents and oceans. These include volcanic ridges, island chains, seamounts, plateaus, large igneous provinces, and others. Understanding the structure, origin, and composition of these features provides insights into the Earth’s mantle dynamics, evolution, economic resources, and deep interior to surface thermochemical exchange. From well-known to lesser-studied cases of intra plate volcanism, the resulting structures often present challenges to available overarching models which aim to explain their formation and evolutionary history. Their diverse morphology, geochemical signatures, and geophysical characteristics highlight associated complexities, requiring increasingly multidisciplinary studies. This session invites novel perspectives from integrated methods–including, but not limited to, geochemistry, geodynamics, geophysics, geochronology, and volcanology–to deepen our understanding of intra plate magmatism. We encourage research of both classic and underexamined intra plate volcanic features to better correlate surface expressions and deep mantle processes.
