“…Furthermore, the W-type fluid inclusions are heavily distributed in the boundaries between the “cloudy centers” and the “clear rims”. This feature suggests that the fluid inclusions in the II-dolomite are related to the precipitation of the dolomite 21 , 53 . The homogenization temperatures of the fluid inclusions in the II-dolomite range from 107 to 212 °C.…”

Natural gas of organic origin is primarily biogenic or thermogenic; however, the formation of natural gas is occasionally attributed to hydrothermal activity. The Precambrian dolomite reservoir of the Anyue gas field is divided into three stages. Dolomite-quartz veins were precipitated after two earlier stages of dolomite deposition. Fluid inclusions in the dolomite and quartz are divided into pure methane (P-type), methane-bearing (M-type), aqueous (W-type), and solid bitumen-bearing (S-type) inclusions. The W-type inclusions within the quartz and buried dolomite homogenized between 107 °C and 223 °C. Furthermore, the trapping temperatures and pressures of the fluid (249 °C to 319 °C and 1619 bar to 2300 bar, respectively) are obtained from the intersections of the isochores of the P-type and the coeval W-type inclusions in the quartz. However, the burial history of the reservoir indicates that the maximum burial temperature did not exceed 230 °C. Thus, the generation of the natural gas was not caused solely by the burial of the dolomite reservoir. The results are also supported by the presence of paragenetic pyrobitumen and MVT lead-zinc ore. A coupled system of occasional invasion by hydrothermal fluids and burial of the reservoir may represent a new genetic model for natural gas accumulation in this gas field.

“…Many studies have noted liquid occlusions during crystal growth from solution (Belyustin and Fridman, 1968; Brooks, et al, 1968;Denbigh and White, 1966). In melt growth, solid impurity concentrations exceeding solid solubility limits or forming a second phase during zone refining or progressive freezing at high velocities have been noted (Baker and Cahn, 1969;Hellawell, 1965; Sharp and Hellawell, 1970a;Wilcox, 1970; Wilcox and Zief, 1967a).…”

“…36 However, the established mechanisms for occlusion formation under large supersaturation conditions should still hold. 25,37,38 If operative in ec-LLS, this type of crystallization suggests slower growth rates at potentials that limit the extent of supersaturation in the liquid metal ought to lead to lower levels of metal incorporation. More explicit information on the kinetics of crystal growth and the mobility of atoms on a surface immersed in a specific liquid metal would help guide such studies.…”

Crystalline germanium (Ge) micro-and nanowires have been grown from aqueous electrolytes through an electrochemical liquid-liquid-solid (ec-LLS) process using eutectic bismuth indium (e-BiIn) alloy as the liquid metal electrode. This alloy represents the first non-Hg or non-Ga containing liquid metal to be used for the growth of a group IV semiconductor crystal below the boiling point of water. The electrochemical stability of e-BiIn in aqueous electrolyte was assessed through cyclic voltammetry, which showed the metal alloy was destabilized either by anodic oxidation at potentials more positive than −1.0 V vs E(Ag/AgCl) or by cathodic reduction of Bi to BiH 3 at potentials more negative than −1.4 V vs E(Ag/AgCl). Within this potential window, ec-LLS produced Ge micro-and nanowires that were evaluated with scanning electron microscopy, high resolution transmission electron microscopy, and selected area electron diffraction. The cumulative analyses showed pronounced crystallinity in the as-prepared Ge microwires and nanowires, with nanowires showing an unexpected coiled morphology. Atom probe tomography data showed some incorporation of In and Bi at 6 and 3 at. %, respectively. The tomography data further demonstrated that the distribution of the metals was not uniform, as In-rich clusters were observed. A high doping character in the as-prepared Ge nanowires was separately confirmed with two-terminal resistivity measurements. In total, this work not only identifies a new liquid metal type that is amenable for ec-LLS but also suggests strongly that the composition of the liquid metal influences the resultant crystal size, shape, and purity.
