Volcanism is a potentially important natural source of mercury (Hg) to the environment.
However, its impact on the global Hg cycle remains poorly understood despite advances …

Selenium is a chemical element with major environmental implications, due to the extremely
narrow range between essential and toxic concentrations. Volcanoes emit significant …

The Siberian Traps large igneous province (STLIP) is commonly invoked as the primary
driver of global environmental changes that triggered the end-Permian mass extinction …

Economically exploitable deposits of metallic minerals (ore deposits) form in the Earth's crust
through a variety of geologic processes. These involve extraction of metals at low …

Mapping closely to how ore deposit geology is now taught, this textbook systematically
describes and illustrates the major ore deposit types, linking this to their settings in the crust …

Porphyry deposits, our main source of copper and of significant amounts of Mo, Re and Au,
form at convergent margins in association with intermediate-felsic magmas. Although it is …

Abstract High-temperature (1084° C) fumarolic emissions from a spatter cone at the Erta Ale
north pit crater granted a rare opportunity to collect Giggenbach bottles, condensates, and …

As volatile and variably mobile components, halogens play key roles in magmatic,
metasomatic, mineralizing, and volcanic processes by influencing the physical and chemical …

Terrestrial mosses are promising tracers for research concerning metal atmospheric
deposition and pollution. Concentrations of Cr, Co, Ni, Zn, Sr, Cd, Ba, and Pb in different …

Ambrym volcano, in the Vanuatu arc, is one of the most active volcanoes of the Southwest
Pacific region, where persistent lava lake and/or Strombolian activity sustains voluminous …
