The development of analytical and computational techniques and growing scientific funds
collectively contribute to the rapid accumulation of geoscience data. The massive amount of …

We define tephras and cryptotephras and their components (mainly ash-sized particles of
glass±crystals in distal deposits) and summarize the basis of tephrochronology as a …

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 diverse suite of trace elements incorporated into apatite in ore-forming systems has
important applications in petrogenesis studies of mineral deposits. Trace element variations …

Zircon geochemistry provides a sensitive monitor of its parental magma composition.
However, due to the complexity of the uptake of trace elements during zircon growth …

The study of artifacts is fundamental to archaeological research. The features of individual
artifacts are recorded, analyzed, and compared within and between contextual …

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

The possibility of identifying and quantifying agricultural areas objectively and quickly is a
relevant aspect in the Brazilian agricultural context, given the territorial extent of the country …

Crystals within volcanic rocks record geochemical and textural signatures during magmatic
evolution before eruption. Clues to this magmatic history can be examined using crystal size …

Layers of far-travelled volcanic ash (tephra) from explosive volcanic eruptions provide
stratigraphic and numerical dating horizons in sedimentary and volcanic sequences. Such …
