Exploring the structural controls on helium, nitrogen and carbon isotope signatures in hydrothermal fluids along an intra-arc fault system
There is a general agreement that fault-fracture meshes exert a primary control on fluid flow
in both volcanic/magmatic and geothermal/hydrothermal systems. For example, in …

The chemical composition and evolution of volcanic lakes
JC Varekamp - volcanic lakes, 2015 - Springer
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 …
