“…For the calculations the same routine was used as for the determination of fluid inclusion compositions [17]. The integrated band intensities were corrected for cross-section factors of 6.4 and 7.6 for H 2 S and CH 4 , respectively [18]. It was assumed that the cross-sections do not vary with cage type or the overall composition of the hydrate.…”

Raman spectroscopic investigations on natural samples from the Integrated Ocean Drilling Program (IODP) Expedition 311 : Indications for heterogeneous compositions in hydrate crystals AbstractNatural gas hydrates usually are found in the form of structure I, encasing predominantly methane in the hydrate lattices as guest molecules, sometimes also minor amount of higher hydrocarbons, CO 2 or H 2 S. Raman spectroscopy is an approved tool to determine the composition of the hydrate phase. Thus, in this study Raman spectroscopic analyses have

“…Carbonates are distinguishable by their diagnostic Raman spectra (Bischoff et al, 1985;Burke, 2001;Gillet et al, 1993;Frost & Dickfos, 2007;Liu & Mernagh, 1990;Perraki et al, 2006;Scheetz & White, 1977;Williams et al, 1992 and references therein). However, the pressure dependence of the vibration frequencies is well known only in the case of particular carbonates (Gillet et al, 1993).…”

The presence of aragonite in polycrystalline carbonate inclusions in garnet in diamond-grade metamorphic rocks from the Kokchetav Massif, N. Kazakhstan was identified for the first time by means of Raman analyses and mapping, cathodoluminescence images and optical and scanning electron microscopy. Aragonite appears within the inclusions as dirty, chaotically oriented materials surrounded by a clean monocrystalline calcite shell; the grain boundary between the host-garnet and the aragonite-bearing inclusions is often characterized by a wavy or amoeboid shape; no cracks occur around the aragonite-bearing inclusions; no significant shift in the main aragonite Raman band was measured. These observations indicate that residual pressure within the inclusion is minor. These features are inconsistent with an origin of aragonite at peak metamorphic conditions (6 GPa) by decomposition of dolomite.

“…LRSA was conducted at the State Key Laboratory of Geological Processes and Mineral Resources (GPMR), China University of Geosciences, Wuhan, China. In order to confirm the volatile species of FIs, representative samples were carried out with a Renishaw 1000 Raman microspectrometer according to the method of Burke [26]. Spectrograph aperture was chosen as 25 m or 50 m pinhole.…”

Nature and Evolution of the Ore-Forming Fluids from Nanmushu Carbonate-Hosted Zn-Pb Deposit in the Mayuan District, Shaanxi Province, Southwest China

The Nanmushu carbonate-hosted Zn-Pb deposit is located in the Mayuan district of Shaanxi Province, a newly discovered metallogenic district next to the Sichuan Basin, in the northern margin of the Yangtze Block, which is the largest and the only one that is currently mined in this district. The 34 S values of sulfides are characterized by positive values with a peak around +18‰, and the reduced sulfur may have derived from reduction of SO 4 2− from paleoseawater or evaporitic sulfates that have possibly been leached by basinal brines during mineralization stage. Detailed fluid inclusion study shows two types of fluids in the sphalerite, quartz, dolomite, calcite and barite, that is, aqueous-salt dominant inclusions (type I) and hydrocarbon-bearing inclusions (type II). The Laser Raman spectroscopy study shows occurrence of certain amount of CH 4 , C 4 H 6 , and bitumen. The salinities show similar values around 6 to 12 wt% NaCl equivalent but a decreasing temperature from early to late stages (typically 200 ∘ to 320 ∘ C in stage I, 180∘ to 260 ∘ C in stage II, and 140 ∘ to 180 ∘ C in stage III). These features may be related to basinal brines mixing between an external higher salinity CaCl 2 ± MgCl 2 -rich fluid and a local H 2 O-NaCl methane-rich fluid.
