Veins and Hydrothermal Deposits

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

Stibnite Mining District Wikipedia

The Stibnite Mining District is one of the most historic mining districts in all of Idaho. The site is rich with minerals, including gold, silver, antimony and tungsten.Over the last hundred years, it has been home to thousands of miners, operated by several different mining companies and was critical to the U.S. war effort in the 1940s and 1950s.

Gold Occurrences in New Brunswick Gold, Mining and

By virtue of its diverse geological history New Brunswick has several different ways in which gold can occur. In northern New Brunswick gold is found in the form of epigenetic formations in quartz veins following major faults and shear zones. It is also found in gossens caused by the oxidation of volcanogenic massive sulfide (VMS) deposits of metals including pyrite and other iron sulfides.

Tungsten Deposits in the United States ScienceBase-Catalog

Tungsten deposits have been mined in the United States since the late 19th century, but there has been minimal production of tungsten from mines in the United States since price crashes in the 1980's. Tungsten is necessary for strategic, consumer, and commercial applications. Due to its strength, hardness, high melting and boiling points, tungsten is used in wear-resistant applications

Intrusive related gold usually also contains copper, and is often associated with tin and tungsten, and rarely molybdenum, antimony and uranium. Intrusive-related gold deposits rely on gold existing in the fluids associated with the magma (White, 2001), and the inevitable discharge of thesehydrothermal fluids into the wall-rocks (Lowenstern, 2001).

Introduction to metals in the New Zealand Environment

Hence, much of the science of geological controls on metals in the New Zealand environment is tied to the geology of gold deposits. Two distinctly different gold deposit types occur (see maps above). Both of these are hydrothermal deposits, i.e., they were formed by hot water moving through cracks in the rocks before the rocks were deeply eroded.
