Nondestructive proton-induced X-ray emission (PIXE) analysis is used to measure the concentrations of base metals and other heavy elements in single hypersaline brine inclusions low-salinity vapor inclusions, which are intimately associated within a granite-hosted quartz-cassiterite vein Mole Granite (New South Wales, eastern Australia). Microther-mometric measurements Raman microspectrometry on same complement data.The have an estimated composition (in wt %): NaCl, 20; KCl, 7; CaCl 2 , 0.9;...

Abstract The S anshandao gold deposit, located at northwestern edge of the J iaodong P eninsula, eastern N orth C hina raton, is one largest deposits in province. In disseminated‐ and stockwork‐style ores are hosted M esozoic granitoids. Mineralization alteration largely controlled by regional anshandao– angshang fault. Sericite separated from rocks mineralized zone yields an Rb–Sr isochron age 117.6 ± 3.0 Ma. ore‐forming fluids deposit contain CO 2 ‐H O‐NaCl±CH 4 with low to intermediate...
Kiruna-type iron oxide-apatite (IOA) deposits, an important source of iron, show close associations with andesitic subvolcanic intrusions. However, the processes ore formation and mechanism controlling concentration remain uncertain. Here, we report widespread presence high-temperature (>800°C) water-poor multisolid hydrosaline liquid inclusions in pre- syn-ore minerals from IOA deposits eastern China. These consistently homogenize to a phase by vapor disappearance mostly contain 3 10 wt %...
Abstract Raman spectroscopy was used to distinguish the individual members of two feldspar subgroups. All feldspars were found exhibit a characteristic, intense line between 500 and 515 cm −1 which is attributed mixed SiOSi (or SiOAl) bending/stretching mode. However, discrimination related within each subgroup relies on change in frequencies band widths occur external lattice modes SiO stretching region. Spectra recorded from single crystals powders demonstrate that laser microprobe...
The world’s most ancient biogenic structures are found in the North Pole Dome of Western Australia, where 3.47-Gyr-old algal mats and stromatolites closely associated with bedding-conformable discordant laminar quartz, chalcedony, barite. Barite-rich quartz hydrothermal veins similar mineralogy occur throughout stratigraphy below conformable structures. With exception large volume barite, these exhibit textures alteration (quartz-chalcedony-chlorite-illite ± calcite-adularia-pyrite) typical...

We reinterpret the regional geologic setting of giant Muruntau gold deposit and report new 40 Ar/ 39 Ar isotope age determinations a laser Raman microprobe analysis fluid inclusions. New hydrothermal sericite selvages to gold-stage quartz veins are in excellent agreement with older Rb-Sr dates on auriferous veins. They suggest Triassic formation at 245 220 Ma, some 30 m.y. later than subjacent felsic intrusions as defined by data. These call into question role magmatic fluid, metal, heat...

Studies of liquid-vapor-multisolid (L-V-nS) and liquid-vapor ± halite fluid inclusions suggest that at least three fundamentally different brines were involved in the genesis Proterozoic ironstone-hosted Starra Au-Cu deposit. Element concentrations determined from proton-induced X-ray emission (PIXE) analysis groups L-V-nS early barren magnetite ironstone stage (400°–550°C) younger mineralization (220°–360°C) covary over concentration ranges greater than deduced analytical errors. The two...
This study reports results of mass transfer calculations using chemical modeling software (HCh) to determine parameters that may have had a significant effect on gold deposition in turbidite-hosted Phanerozoic metamorphic terranes. The system modeled was Al-As-Au-C-Ca-Cl-Cu-Fe-H-K-Mg-N-Na-O-S-Sb-Si simulate fluid-rock interaction, gas partitioning, and mineral precipitation veins.
