The vents of such geysers are artificial, but are tapped into natural hydrothermal systems.

Pocket Basin was originally an ice-dammed lake over a hydrothermal system.

The hydrothermal system is in its waning stages of existence.

The metals are epithermal deposits from hydrothermal systems related to volcanic activity.

Because the carbonates were near silicate minerals and clays hydrothermal systems like the deep sea vents on Earth may have been present.

There are also numerous hot springs and fumaroles on the island, due to an active hydrothermal system.

The reservoir is a lithologically capped hydrothermal system with three layers of reservoirs underlying one another.

The development of large-scale hydrothermal systems was thus inhibited.

Research studies have concerned the fundamental processes of magmatism, hydrothermal systems, and ore deposition.

In hydrothermal systems the circulation of groundwater is driven by a combination of topography and heat sources.
