“…The C1/C2 of some samples conform to that expected for thermogenic release of gas from sedimentary rocks [ Lorenson et al ., ; Bergfeld et al ., ] and are geographically correlated with areas that contain known hydrocarbon seeps [ Love and Good , ; Clifton et al ., ]. Abiotic production of many hydrocarbons is an inevitable result of metastable equilibrium in kerogen‐bearing rocks at typical crustal oxidation states and temperatures between 150 and 300°C [ Shock et al ., ].…”

The Yellowstone Plateau Volcanic Field is characterized by extensive seismicity, episodes of uplift and subsidence, and a hydrothermal system that comprises more than 10,000 thermal features, including geysers, fumaroles, mud pots, thermal springs, and hydrothermal explosion craters. The diverse chemical and isotopic compositions of waters and gases derive from mantle, crustal, and meteoric sources and extensive water-gas-rock interaction at variable pressures and temperatures. The thermal features are host to all domains of life that utilize diverse inorganic sources of energy for metabolism. The unique and exceptional features of the hydrothermal system have attracted numerous researchers to Yellowstone beginning with the Washburn and Hayden expeditions in the 1870s. Since a seminal review published a quarter of a century ago, research in many fields has greatly advanced our understanding of the many coupled processes operating in and on the hydrothermal system. Specific advances include more refined geophysical images of the magmatic system, better constraints on the time scale of magmatic processes, characterization of fluid sources and water-rock interactions, quantitative estimates of heat and magmatic volatile fluxes, discovering and quantifying the role of thermophile microorganisms in the geochemical cycle, defining the chronology of hydrothermal explosions and their relation to glacial cycles, defining possible links between hydrothermal activity, deformation, and seismicity; quantifying geyser dynamics; and the discovery of extensive hydrothermal activity in Yellowstone Lake. Discussion of these many advances forms the basis of this review."This whole region was, in comparatively modern geologic times, the scene of the most wonderful volcanic activity of any portion of our country. The hot springs and the geysers represent the late stages-the vents or escape pipes-of these remarkable volcanic manifestations of the internal forces. All these springs are adorned with decorations more beautiful than human art ever conceived, and which have required thousands of years for the cunning hand of nature to form" [Hayden, 1883, p. 70]. Ferdinand V. Hayden led the 1871 geological survey of northwestern Wyoming, leading to the establishment of Yellowstone as the first U.S. National Park in 1872.

“…At the present time, the abiotic synthesis of organic compounds in the hydrothermal systems of mid-ocean ridges has been confirmed in a number of publications (e.g., [44][45][46]). Alkanes and carboxylic acids represent some of the most abundant organic structure types found in natural hydrothermal systems and sedimentary basin fluids.…”

The origin of phosphorus metabolism is one of the central problems in the context of the emergence of life on Earth. It has been shown that the C-H-O system can be transformed into a four-component C-H-O-P system with the formation of a gluconeogenesis path in a possible Archean hydrothermal condition under the influence of a phosphorus chemical potential. This system became the energy supply basis for protometabolism, and facilitated the formation of a new CO 2 fixation cycle (the reductive pentose phosphate pathway).The modular design of central metabolism in the C-H-O-P system is derived from the parageneses (associations) of certain substances, and the emerging modules in turn associate with each other in certain physical and chemical hydrothermal conditions. The assembly of malate, oxaloacetate, pyruvate, and phosphoenolpyruvate is a reversible "turnstile -like" mechanism with a switching of reaction direction that determines the trend of specific metabolic systems development.

“…volcanic and geothermal areas, are still relatively scarce (Tassi et al, 2015 and references therein), although VOCs are commonly found in significant concentration in CO 2 -dominated fluids released from these natural systems (e.g. Stoiber et al, 1971;Isidorov et al, 1990Isidorov et al, , 1992Jordan et al, 2000;Capaccioni et al, 2001Capaccioni et al, , 2004Schwandner et al, 2004Schwandner et al, , 2013Tassi et al, 2005Tassi et al, , 2009bTassi et al, , 2013Shock et al, 2013).…”
