Applying Stable Isotopes To Mineral

Nesbitt 1996 discussed the applications of oxygen and hydrogen isotope ratios to exploration for hydrothermal ore deposits. Nesbitt provided a review of previous studies that showed kilometer or larger-scale isotopic alteration halos around different mineral deposit types, in which stable isotope ratios may differ by more than 1 more than 10.

Based on the above discussions and comparisons of geological and geochemical characteristics with typical orogenic gold deposits, we propose that the Yuka gold deposit has features similar to those of typical orogenic-type gold deposits 1, 6, 7, 81, 88 1 the Yuka gold deposit ore-forming fluid is of low salinity and CO 2-rich, which is a .

Archaean Lode Gold Deposits The Solute Source

Abstract. On a regional scale lode gold deposits typically occur throughout the entire spectrum of greenstone belt stratigraphy. In the Abitibi Belt lode deposits are sited at the base of the volcanic cycle Noranda, at the boundary of two volcanic cycles Timmins and in the stratigraphically highest groups at Kirkland Lake and Bousquet.

In a similar manner to S isotope data, all of the Pb isotope data overlap with the compositions of whole rocks from Mesozoic granites and dikes, as well as Precambrian metamorphic rocks Figure 14, and are consistent with the lead isotope compositions of most gold deposits in Jiaodong . These values overlap the field of Late Jurassic Linglong .

Geology Fluid Inclusion And Isotope Constraints On

In the following 10 years, several other gold deposits were discovered around Jinshan, including the Huaqiao, Bashiyuan, Hamashi, Xijiang, and Shibei gold deposits. To date, the proven gold reserves at the Jinshan deposit are up to 180 metric tons with gold grades ranging from 4 to 20 g t 1.

Carlintype Gold Deposit Wikipedia

Carlintype gold deposits are sediment-hosted disseminated gold deposits. These deposits are characterized by invisible typically microscopic andor dissolved gold in pyrite and arsenopyrite. This dissolved kind of gold is called Invisible Gold, as it can only be found through chemical analysis. The deposit is named after the Carlin mine .

The gas and liquid chemical compositions and the carbon, hydrogen and oxygen isotopic compositions of the fluid inclusions show that the ore-forming fluids of copper-gold deposits have the same characteristics and evolution tendency, which reflects that the.
