“…Other studies have shown that such carbon isotopic reversals can in fact be produced in typical thermogenic hydrocarbon deposits during migration, mixing and oxidation of gases (Jenden et al, 1993b;Prinzhofer and Huc, 1995;Lorant et al, 1998;Snowdon, 2001;Du et al, 2003;Huang et al, 2004). On the other hand, controlled experiments designed to produce hydrocarbons via abiogenic reactions do not consistently produce the isotopic reversal trend (Hu et al, 1998;McCollom and Seewald, 2006;Fu et al, 2007;Taran et al, 2007;2010). Dai et al (2005) suggested that the mixture of different original organic gases would also cause the carbon isotopic reversals of natural gas by numerical simulation.…”

“…These abiogenic natural gases generally show a reversal pattern of carbon isotopic values for methane and their molecular homologues (i.e., 13 C 1 > 13 C 2 > 13 C 3 > 13 C 4 , Des Marais et al, 1981;Jenden et al, 1993a;Dai et al, 2005;Sherwood Lollar et al, 2002;2008). Abiogenic natural gases were thought forming by Fischer-Tropsch Synthesis (FTS) under subsurface ( Hu et al, 1998;Horita and Berndt, 1999;Sherwood Lollar et al, 2002Fiebig et al, 2007;Fu et al, 2007;Taran et al, 2007Taran et al, , 2010Proskurowski et al, 2008, Proskurowsk, 2010 or by water-rock interaction under the crust (Anderson et al, 1984;Douglas and Seyfried, 2004).…”

AbstractsTwo types of experiments of source rocks pyrolysis with volcanic reservoir rock and without one were conducted under hydrothermal condition and at 200 ˚C in gold tube system. The experiments result shows that there is a higher concentration of hydrocarbon gases generated in the experiment with rhyolite of reservoir stone and water than that with only water. Moreover, the hydrocarbon gases generated by experiments with rhyolite show a full reserved pattern of carbon isotope. This indicated that the FST reaction could happened between source rocks and volcanic reservoir rock at relatively low temperature.The numerical calculation for the carbon isotope of the gases from mixture between the gases from our FTS experiments and the typical organic hydrocarbon gases from deep layers of Songliao basin show that the contamination of a little FTS gas (<5% ,v/v) could cause the carbon isotope composition of thermal gases great variation. So, Fischer-Tropsch synthesis conducted in volcanic reservoir stone is an un-negligible factor caused the reversed pattern of carbon isotopic for natural gases developed in deep layers, Songliao Basin. This also indicated that the natural gases in deep layers of the basin are organic origin chiefly.

“…In general, the CH 4 -rich hydrothermal fluids may come from three ultimate sources: (1) abiogenic origin derived from the mantle [33,34]; (2) abiogenic origin derived from postmagmatic alteration by Fischer-Tropsch type synthesis [35][36][37]; (3) incorporation of thermally decomposed organic material (thermogenesis) or/and products from microbial processes (bacteriogenesis) [38][39][40][41]. The deposit characteristics (without postmagmatic alteration) and sulfur isotope characteristics excluded the abiogenic origin.…”

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.

“…Besides being an excellent and rigorous teacher in the field, Yuri has always been firmly grounded in laboratory analyses and theoretical approaches (Osadchii et al 1997;Taran 2003Taran , 2005Taran et al 2007). Yuri's approach to collecting and analyzing samples followed by rigorous and creative interpretation of the results continues to be an inspiration for many scientists working on active volcanic and hydrothermal systems.…”
