Carbon exists in many forms in the Earth's mantle: as fluids, dissolved as oxidized carbonate species (Pan and Galli ) or as reduced hydrocarbons
There is considerable evidence for continuing, latestage interaction between the magmatic system at Merapi volcano, Indonesia, and local crustal carbonate
In the case of natural gases with CO 2 / 3 He ≫10 10, the CO 2 can only reasonably be produced from crustal (carbonate) sources ().The origin of(CO 2 with CO
In addition, buried, highly reflective seismic structures just below the studied deposits are interpreted as magmatic intrusions which would have provoked contact
A magmatic carbon source is considered more likely on the basis that (1) evidence of and the cause for widespread marine carbonate dissolution in the
Fluid inclusions have been widely used to understand behaviour of ore forming fluids and the magmatic immiscibility such as silicate melt, H2OCO2, hydrosaline melt, dense CH4 and sulphidemetal
Abstract Much of Earth’s carbon resides in the “deep” realms of our planet: sediments, crust, mantle, and core. The interaction of these deep reservoirs of

Carbon exists in many forms in the Earth's mantle: as fluids, dissolved as oxidized carbonate species (Pan and Galli ) or as reduced hydrocarbons (Sverjensky and Huang ) or as solid carbonate (Boulard et al. ; Cerantola et al. ); as elemental carbon (graphite and diamond; Shirey et al. 2013) in the deep mantle; and as
The progressive contribution of magmatic CO2 has been recognized from the retrograde mineral paragenesis as well as from the isotopic composition of associated carbonates. The mineralization at the Sasa PbZnAg
A magmatic carbon source is considered more likely on the basis that (1) evidence of and the cause for widespread marine carbonate dissolution in the sedimentary successions are not apparent, (2) dawsonite is widespread in both marine and nonmarine facies, (3) the region has been the site of major igneous activity, (4) other dawsonite
The mineralization at the Sasa PbZnAg deposit shows many distinctive features typical for base metal skarn deposits including: (1) a carbonate lithology as the main immediate host of the mineralization;
Abstract Much of Earth’s carbon resides in the “deep” realms of our planet: sediments, crust, mantle, and core. The interaction of these deep reservoirs of carbon with the surface reservoir (atmosphere and oceans) leads to a habitable surface environment, with an equitable atmospheric composition and comfortable range in
Magmatichydrothermal gold–copper deposits in postsubduction settings represent essential targets for mineral exploration, but controls on their formation remain controversial. The early Cretaceous lode Au districts that formed during lithosphere destruction of the North China Craton provide an ideal opportunity to better understand
magmatic fluids in the active hydrothermalmagmatic systems may provide the additional material for the interpretation of the processes responsible for the formation of hydrothermal oremagmatic fields. Besides water, carbon dioxide is the most common volcanic component. Its маntlemagmatic origin is
Because of the insufficient reliable dating of intrusive rocks, the relationship between mineralization and the magmatic activities is still unknown. In order to study this key scientific issue and the oreforming processes of the Zoige uranium ore field, the LAICPMS Fruitful UPb dating of magmatic rocks was obtained: 64.08±0.59 Ma for
An intimate relationship between magmatic sulfides and carbonate phases has recently been observed in the mineralized mafic intrusions that make up the Munali deposit in Zambia ( Holwell et al
Magmatic deposits are mineral deposits that are associated with igneous rocks, such as granite, gabbro, and basalt. They are formed by the cooling and crystallization of magma or lava, which can result in the concentration of various minerals within the solidified rock. Magmatic deposits can be further subdivided into two main

A challenge in monitoring longdormant volcanoes is to discover early signs of reawakening. Mineral springs on Taranaki volcano (2,518 m, New Zealand) have elevated carbonate concentrations, δ 13 C DIC ∼ −5‰ (VPDB) and He isotopes from 5.13 to 5.92 R A, indicating a magmatic volatile source.Stable isotopes demonstrate water

Haman, Gunbuk, and Daejang deposits are neighboring veintype hydrothermal Cu deposits located in the SE part of the Korean Peninsula. These three deposits are formed by magmatichydrothermal activity associated with a series of Cretaceous granodioritic intrusions of the Jindong Granitoids, which have created a series of veins and alterations
The abundance of the carbonate alteration is particularly notable as crustal sources for the CO2 such as marbles or carbonate minerals within the host rocks are very rare. A possible source could be related to the alkaline magmatic suite which, N of the study area, also contains mantlederived carbonatites. To ascertain whether this could be

magmatic sources and additional crustal components, it is important to document the chemical genesis. For arc magmas interacting with carbonate crust, as seen at Merapi, the mechanisms of the crustal assimilation may be deciphered from natural samples and through experiments (Freda et al., 2008; Gaeta et al.,
