Volcanic lake research boosted after lethal gas burst occurred at Lake Nyos (Cameroon) in
1986, a limnic rather than a volcanic event. This led to the foundation of the IAVCEI …

This paper deals mainly with acidic sulphate-chloride (ASC) waters that are discharged at
volcanic edifices, generally, not associated with crater lakes. Geographically, the largest …

Water chemistry of crater lakes, maars and water reservoirs linked to some Mexican
volcanoes within and outside the Mexican Volcanic Belt has been determined for several …

The discovery of sulfate‐rich layered deposits with hematite spherules at the landing site of
the Opportunity rover is consistent with mineral deposition in an aqueous environment. We …

Abstract High fluoride (F) groundwaters (> 1 mg/L) have been recognized as a water quality
problem for nearly a century and occur in many countries worldwide. The affected aquifers …

Volcanic lakes carry fluids that range from ultra acid, high TDS brines to largely meteoric
fluids. Their water compositions are governed by volcanic fluid inputs, which range from …

Volcanic acid sulfate–chloride brines form through absorption of volcanic vapors in shallow
reservoirs of meteoric water. Reaction with surrounding volcanic rocks leads to partial …

Among surface waters, lakes in volcanic areas display the greatest range in pH values: from
negative values up to about 12. The present chapter is a short review of the main features of …

Copahue volcano erupted altered rock debris, siliceous dust, pyroclastic sulfur, and rare
juvenile fragments between 1992 and 1995, and magmatic eruptions occurred in July …

Volcanic lakes are amongst the most spectacular natural features on the planet. These
intersections of magmatic-hydrothermal systems and the Earth's surface are, poetically …
