Abstract Raman spectroscopy can be used to determine density of gases, because the energy fundamental vibrational modes is affected by intermolecular distances. The key problem estimation exact peak positions bands, analyses require a precision that mostly less than pixel resolution modern spectrometers. A new method bands and atomic emission lines in discontinuous spectrum without numerical ma...

In this study, we present new data from microthermometry of fluid inclusions entrapped in hydrothermal veins along the Cocos Ridge from the IODP Expedition 344 Site U1414. The results of our study concern a primary task of IODP Expedition 344 to evaluate fluid/rock interaction linked with the tectonic evolution of the incoming Cocos Plate from the Early Miocene up to recent times. Aqueous, low ...

The concentration of halogens (Cl, Br) and sulfate in seawater during the Archaean eon have important implications for the evolution of Earth’s hydrosphere and atmosphere and the development of early life. Insights into the composition of Archaean seawater and hydrothermal fluids can be obtained by direct analysis of fluid inclusions preserved in Archaean sediments and hydrothermal systems. Her...

Abstract Stibnite was mined until the end of twentieth century in Schlaining ore district, Austria, near easternmost border Eastern Alps where windows Penninic ophiolites and metasediments are exposed below Austroalpine tectonic units. In Early Miocene, structurally controlled small vein metasomatic stibnite-quartz deposits were formed Mesozoic calcareous marbles calcite schists. Fluid inclusio...

introduction a wide variety of world-class porphyry cu deposits occur in the urumieh-dohktar magmatic arc (udma) of iran.the arc is composed of calc-alkaline granitoid rocks, and the ore-hosting porphyry intrusions are dominantly granodiorite to quartz-monzonite (zarasvandi et al., 2015). it is believed that faults played an important role in the emplacement of intrusions and subsequentporphyry...

Abstract The Bundelkhand “giant quartz reef” (BGQR) system comprises 20 major reefs which run for tens of km in strike length average width 40 m and occurs spatial intervals 12–19 the craton, North Central India. BGQR is distinct from vein systems originating crustal scale shearing observed ancient as well modern convergent tectonic settings. Fluid inclusions studied are intriguingly diverse al...

The ternary system H2O-NaCl-CO2 is one of the most important fluid systems in geochemistry and petrology. However, there is little information on the phase equilibrium and PVT properties in this system at salinities above 6 wt.% NaCl. In this study, PVTX data were obtained experimentally by using the synthetic fluid inclusion technique in conjunction with conventional microthermometry and a hyd...
