Tephrochronology studies the deposits of explosive volcanic eruptions in the stratigraphic
record. The Southern (SVZ, 33–46° S) and Austral (AVZ, 49–55° S) Volcanic Zones of the …

A volcano is a complex system, and the characterization of its state at any given time is not
an easy task. Monitoring data can be used to estimate the probability of an unrest and/or an …

We introduce a new approach, based on machine learning, to estimate pre‐eruptive
temperatures and storage depths using clinopyroxene‐melt pairs and clinopyroxene‐only …

The major-element chemical composition of garnet provides valuable petrogenetic
information, particularly in metamorphic rocks. When facing detrital garnet, information about …

Magnetite is a reliable indicator mineral for exploration because it records petrogenetic
processes and discriminate deposit types. Binary discriminant diagrams have limits to …

Alaska contains over 130 volcanoes and volcanic fields that have been active within the last
2 million years. Of these, roughly 90 have erupted during the Holocene, with many …

Although analyses of tephra-derived glass shards have been undertaken in New Zealand
for nearly four decades (pioneered by Paul Froggatt), our study is the first to systematically …

Lakes and bogs in northeastern North America preserve tephra deposits sourced from
multiple volcanic systems in the Northern Hemisphere. However, most studies of these …

Although machine learning (ML) has brought new insights into geochemistry research, its
implementation is laborious and time‐consuming. Here, we announce Geochemistry π, an …

The delineation of sediment facies provides essential background information for a broad
range of investigations in geosciences but is often constrained in quality or quantity. Here …
