TL;DR: The Rainbow vent field is an ultramafic rock-hosted seafloor hydrothermal system located on the Mid-Atlantic ridge issuing high temperature, acidic, metal-rich fluids.

TL;DR: The Rainbow vent field is an ultramafic-hosted hydrothermal system located on the Mid-Atlantic Ridge characterized by vigorous high-temperature venting (∼365°C) and unique chemical composition of fluids: high chlorinity, low pH and very high Fe, and rare earth element (REE) contents as discussed by the authors.

TL;DR: The Menez Gwen and Lucky Strike seafloor hydrothermal systems on the Mid-Atlantic Ridge are influenced by the Azores plume, which results in a geochemically enriched character of the host basalts as mentioned in this paper.

TL;DR: In this article, the authors studied inclusions in plagioclase and olivine phenocrysts in these basalt basalt lavas and found that the less incompatible element enriched type II lavas are more enriched in Cu than type I, an observation that is relevant to the origin of metals characteristic of these particular basalt-hosted seafloor hydrothermal systems.

TL;DR: In this article, a study of melt inclusions in rocks associated with modern and ancient seafloor hydrothermal systems was carried out using secondary ion mass spectrometers (SIMS) in order to obtain quantitative data for which they used as standards quenched glasses with known similar compositions.
