Q001 hydrothermal fluids
WebDec 1, 2024 · Magmatic-hydrothermal fluids play a key role in a variety of geological processes, including volcanic eruptions and the formation of ore deposits whose metal content is derived from magmas and transported to the site of ore deposition by means of hydrothermal fluids. WebAug 28, 2024 · These hydrothermal fluids are rich in sulfur, sodium, potassium, copper, tin, tungsten, and other elements with relatively high solubilities. Hydrothermal fluids dissolve other elements as they flow through rocks and eventually cool to deposit minerals in hydrothermal deposits.

WebJan 1, 2015 · The major controls on vent fluid compositions in arc and back-arc settings are the same as those at mid-ocean ridges, although there is abundant evidence that magmas directly supply a number of components, including CO 2 and metals, to the hydrothermal fluids and boiling affects many of the hydrothermal systems at the volcanic fronts of the ... WebApr 3, 2024 · 1. Introduction. Hydrothermal mineralization is one of the primary ore-forming processes on Earth, existing widely not only in extensional tectonic settings, for example, continental or oceanic rifts, but also in compressional ones, such as subduction zones and collisional orogenic belts [].Traditionally, studies on fluid-rock interaction [2, 3], fluid …
