    Hydrothermal solution. Hydrothermal mineral deposits are those in which hot water serves as a concentrating, transporting, and depositing agent. They are the most numerous of all classes of deposit. Hydrothermal deposits are never formed from pure water, because pure water is a poor solvent of most ore minerals. Rather, they are formed by hot brines, making it more . Geological classification of lode gold deposits is further complicated by the following factors: 1. A significant number of large deposits are the results of superposi-tion of two or more systems, or of superposition of distinct com-ponents of hydrothermal systems due to telescoping (Sillitoe, ): this can lead to apparently hybrid deposit.

    These ages are much younger and more uniform than would be expected if the ores were formed at the time of deposition of the host rocks, but they compare favorably to the million years determined as the mean age of four pitchblende samples from hydrothermal veins in the Colorado Front Range. 5. Fractures form in Earth's crust as mountains rise. Hydrothermal fluids flow into these spaces and form gold-bearing quartz veins. These fluids are created by hot, deeply buried metamorphic rocks.

    The formation of vein mineralization in the Harz Mountains developed from the Late Variscan through to Upper Cretaceous times. Hydrothermal vein-type Pb-Zn (Ag), Ba-F, Ba-Fe and F-Ba mineralization was deposited in the Mesozoic (Triassic through Late Cretaceous) e.g., [65,66,67].

paperback. DM / $ No. Mineral Deposits of the Erzgebirge/Krusne hory. When you first look at a quartz vein in a rock it looks like a very narrow vein but in reality a quartz vein develops into a sheet like body of quartz or other mineral that is carried in the cracks and fissures in the rock by a hot aqueous solution that is deposited through precipitation.

The flow of water involved in this mechanism is usually hot water that is due to hydrothermal. Hydrothermal mineral deposits are accumulations of valuable minerals which formed from hot waters circulating in Earth's crust through fractures. They eventually create rich-metallic fluids concentrated in a selected volume of rock, which become supersaturated and then precipitate ore some occurrences, minerals can be extracted at a profit by mining.

Only few isotopic ages of hydrothermal vein deposits in the Harz Mountains are available. Mertz et al.

Monogr Ser Mineral Deposits – Hydrothermal fluid flow along fault zones in the Harz Mountains led to widespread formation of economic vein-type Pb–Zn ore and Ba–F deposits during the Mesozoic. We reconstruct the fluid flow system responsible for the formation of these deposits using isotope ratios (δ2H and δ18O) and anion and cation contents of fluid inclusions in ore.

The recognition of hydrothermal mineralization in complex pegmatites has led me to speculate as to whether or not such a phase possibly con-nects pegmatites with ore-bearing hydrothermal veins.

It has been ap-preciated for some time that both types of deposits are formed from re-sidual magmatic liquids. 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.

Hydrothermal fluid flow along fault zones in the Harz Mountains led to widespread formation of economic vein-type Pb–Zn ore and Ba–F deposits during the Mesozoic. In Fig. 1, the sulphur isotope ratios of the NEGB are compared to those from vein deposits in the Harz Mountains and the Kupferschie- fer.

These mineralisations contain base metal sul- phides deposited during early stages of hydrothermal activity as well as barite formed during later stages. Vein deposits include most gold mines, many large silver mines and a few copper and lead-zinc mines. Veins commonly consist of quartz (sometimes of several varieties such as amethystine or chalcedony) usually occurring as interlocking crystals in a variety of sizes or as finely laminated bands parallel to the walls of the vein.

In geology, a vein is a distinct sheetlike body of crystallized minerals within a form when mineral constituents carried by an aqueous solution within the rock mass are deposited through hydraulic flow involved is usually due to hydrothermal circulation.

Veins are classically thought of as being the result of growth of crystals on the walls of planar. Geosciences, an international, peer-reviewed Open Access journal. Dear Colleagues, Magmatic-hydrothermal fluid circulation systems in the Earth’s crust are related with intermediate to felsic hydrous magmas, mainly at convergent plate margins, providing heat and mass transfer for the formation of ore deposits including base, precious and rare metals.(Hedenquist et al., ).

However, ore formation in the interior of modern hydrothermal-magmatic systems is either declared on the basis of indirect data (stties of volcanic gases and udy of metal bearing proper hydrothermal solutions), or mineral ore formation processes are researched near and on the daylight surface (Giggenbach et al., ).Hydrothermal mineral deposit, any concentration of metallic minerals formed by the precipitation of solids from hot mineral-laden water (hydrothermal solution).The solutions are thought to arise in most cases from the action of deeply circulating water heated by magma.

Other sources of heating that may be involved include energy released by radioactive decay or by faulting of the .
