“…The initial data for calculations were reported previously [42,62,64]. The T Mg/Li estimates for the MV waters derived from numerous active (bubbling) salsas of South Sakhalin MV and by single gryphons with liquefied mud from Pugachev MV, fall within narrow ranges of 93 to 111 • C and 102 to 107 • C, respectively.…”

“…The South Sakhalin MV waters (Figure 5) are of HCO 3 -Cl/Na-Mg type, with low (SO 4 ) − and high Ba contents, three orders of magnitude different from the seawater values [42,64]. These waters have extremely high average Li contents (X av .…”

“…The MV waters of South Sakhalin volcano have HCO 3 -Cl/Na-Mg chemistry (dominated by HCO 3 ) and low salinity (TDS, total dissolved solids), which is common to waters of this kind in the Pacific active belt [21,42,[62][63][64]. During the field observations of 2018, active bubbling salsas (gas flow 7.1-20.8 mL/s) emitted MV water with Eh av.…”

“…They have notable Zn contents, while thermal waters also contain As and Cu, and MV waters show As, Sb and occasionally Pb enrichment. The MV waters in Sakhalin Island, which is located in a wet climate zone, must be diluted with atmospheric precipitation [42,64,67]. The dilution effects (lower concentrations of HCO 3 , Cl, Br, Na, K, Mg, Ca, Li, and As) are commonly observed in the waters of small gryphons.…”

We characterize the mineralogy and geochemistry of Fe, Zn, Pb, Sb, As, Hg, Ag sulfide assemblages from mud masses currently extruded by the onshore South Sakhalin and Pugachev mud volcanoes (Sakhalin Island, Russia). Abundant Tl-rich pyrite in sulfide concentrate samples from the mud volcanoes coexists with common Hg- and Ge-rich sphalerite, as well as with sporadic boulangerite, robinsonite, bournonite, galena, realgar, metacinnabar, cinnabar, acanthite, and chalcopyrite. Sphalerites are remarkably enriched in Hg (locally reaching 27 wt%) and coupled zwith permanent abnormal enrichment in Ge (3008–3408 ppm). According to single-crystal XRD analyses and Raman spectroscopy, both Hg-poor and Hg-rich sphalerites are single-phase (Zn,Hg)Scub compounds. Pyrite is of diagenetic origin, judging by its trace-element chemistry, particular morphology, and heavy S isotope composition. Another assemblage, composed of Pb-Sb-(Hg) sulfide minerals and lesser As, Cu, Ag, and Bi compounds, results from hydrothermal alteration and is genetically related to Neogene volcano-sedimentary rocks found among the ejecta of the mud volcanoes. The composition of impurities in sphalerite from mud masses indicates crystallization at temperatures lower than ~100 °C, under the leaching effect of mud volcano waters.

“…This paper gives a comparative analysis of the chemical and isotope composition of waters on terrestrial mud volcanoes and formation waters from oil and gas fields made on the basis of published hydrogeochemical data. The study made use of consolidated reports on water composition from over 170 mud volcanoes situated in different parts of the world -Azerbaijan, Georgia, India (Andaman Islands), Italy, China, Russia (Kerch Peninsula, Taman Peninsula, Sakhalin Island), USA (Alaska), Taiwan, Trinidad and Tobago, Turkmenistan, Japan [6][7][8]. Specific geochemical characteristics of formation waters are highlighted through the cases of several large oil and gas regions of Russia and other countries [9][10][11][12][13][14][15][16].…”

The paper reports the results of a comparative analysis of the chemical and isotope composition (δ180 and δD) of mud volcanic waters and formation waters from oil and gas fields. Studies show that the waters discharged by mud volcanoes in most cases are very similar to formation waters. The most characteristic geochemical traits of both waters are elevated concentrations of hydrocarbonate ions, iodine, boron, bromine, and a low content of sulfate ions.

The present paper is a comparative study of geochemical characteristics of the emissions of the Yuzhno-Sakhalinsky mud volcano and the sediment-hosted hydrothermal systems Salton Sea and Lusi. The comparative analysis was performed using the data on the content of Cl, Br, SO4, Li, Na, K, Ca, Mg, B, Ba, Sr, Si, oxygen-18 and deuterium in the discharged fluids, as well as on the content of CO2, C1-C5, carbon-13 in CO2 and CH4 in the released gases. It showed the absence of any distinct systematic differences in geochemical parameters between mud volcanoes and sediment-hosted hydrothermal systems. This suggests, inter alia, a need for a detailed geochemical classification of mud volcanoes, which to this day has not been elaborated.
