barite as a gangue mineral in hydrothermal veins

Veins and Hydrothermal Deposits - Geology In

Vein deposits of this nature are a type of hydrothermal deposit because the mineral species which compose the veins were precipitated by hot waters. However, sometimes the preexisting rock wall which contains the vein undergoes alteration. Portions of the host rock may either dissolve and be transported away or else react chemically with the circulating volatile fluids or the newly formed ...

In the Schwarzwald area, southwest Germany, more than 400 hydrothermal veins hosting different gangue and ore mineral assemblages cross-cut the crystalline basement rocks. Many of the post-Variscan fluorite-barite-quartz veins are considered to have precipitated through mixing of a deep saline brine with meteoric, low salinity waters. This hypothesis was tested using carbon, sulfur, and oxygen ...

Carbonates are commonly present as part of the gangue in hydrothermal deposits associated with quartz, phyllosilicates, and barite. Carbonates are a focus of interest to researchers investigating ore-forming systems; fluid inclusion and isotopic data (C, O, Sr, Pb) can give important information on the provenance of hydrothermal fluids (e.g., [1,2,3,4,5,6,7,8,9,10,11,12,13]).

Mineral Resource of the Month: Barite

The mineral barite (barium sulfate), also known as barytes, is most commonly found in hydrothermal veins and as veins in limestone. It is very dense (it has a high specific gravity) and is relatively soft. Those properties make it an excellent weighting agent in drilling muds for petroleum wells. In fact, worldwide, oil and gas drilling account ...
