“…Since the "seep-search strategy" was proposed by Campbell and Bottjer [22], more and more ancient seep deposits were discovered and studied. Today, ancient hydrocarbon seeps have already been recognized from Devonian to Quaternary strata in almost all continents based on occurrences of seep carbonates and/or fossil chemosynthetic assemblages [10,13,14,[16][17][18][19][20][23][24][25][26][27][28]. However, seep carbonates are rarely found from ancient strata in the mainland China.…”

Hydrocarbon seeps, widely occurring in continental margins, have become increasingly focused owing to their close relationships with gas hydrates, strong greenhouse gas methane, and biological resources in extreme environments. Ancient hydrocarbon seeps have already been recognized from Devonian to Quaternary strata worldwide based on seep carbonates or seep-related fossil chemosynthetic assemblages. However, seep-related deposits are rarely found from ancient strata in the mainland China. Here, we report the first discovery of an ancient seep deposit, specifically late Cretaceous seep carbonates from Xigaze in Tibet, China. Xigaze seep carbonates, occurring as nodules, are enclosed in upper Cretaceous turbidite strata in Xigaze forearc basin. These carbonates are composed of authigenic carbonate (56.2% on average), clastic quartz and feldspar (27.3% on average), and clay minerals (chlorite, illite and smectite, 16.5% on average). Clotted micrites, peloids and framboid pyrites are frequently observed, all of which are common in modern seep carbonates. The carbonates have negative  13 C values varying from 27.7‰ to 4.0‰ (V-PDB), suggesting that thermogenic methane is the primary carbon source. Ce/Ce* values revised by eliminating La effects show no real Ce anomaly, indicating the carbonates were primarily precipitated in a weak reducing environment. Overall, these features provide unequivocal evidences that the seafloor of Xigaze forearc basin developed hydrocarbon seeps in late Cretaceous. seep carbonate, carbon isotope, sedimentary fabric, Xigaze, late Cretaceous Citation:Tong H P, Chen D F.

Consequently, rare cavities within micrite and geopetal structures within thyasirid shells are indicative of localized focused flow and faster carbonate cementation (e.g.…”

“…It is likely that during the Late Jurassic to Early Cretaceous their place was occupied ecologically by species of the extinct modiomorphid bivalve genus Caspiconcha, although it is not known if this bi− valve possessed chemosymbionts. The type species of Caspi− concha (C. whithami) was first described from seep carbon− ates of East Greenland (Kelly et al 2000) and another species (C. rubani) was subsequently proposed based on material from the Ukraine (Kiel and Peckmann 2008;Kiel et al 2010). Kiel and Peckmann (2008) and Kiel et al (2010) suggested that the large modioliform bivalve Modiola major Gabb 1869, widely distributed in Upper Jurassic to Lower Cretaceous hy− drocarbon seeps in California, USA , may also belong to Caspiconcha.…”

Two new species ofRetiskenea? (Gastropoda: Neomphalidae) from Lower Cretaceous hydrocarbon-seep carbonates of northern California

Two new Mesozoic gastropod species, provisionally attributed to the minute (height < 5 mm) coiled neomphalid genus Retiskenea?, are described from three geographically isolated, Early Cretaceous, hydrocarbon seep-carbonate sites at Wilbur Springs, Rice Valley, and Cold Fork of Cottonwood Creek, northern California (USA). A fourth paleo-seep locality at Paskenta, of probable Upper Jurassic age, also yielded a single specimen of a morphologically similar microgastropod that may be a neomphalid with affinities to the Lower Cretaceous specimens described herein. the limestone lenses are ~2-260 m in length, ~1-5 m in diameter, and surrounded by forearc siliciclastics of bathyal turbidites or sedimentary serpentinites in the Upper Jurassic to Lower Cretaceous (Tithonian-Albian) Great Valley Group and its equivalents. the Lower Cretaceous microgastropods are tentatively placed in Retiskenea? based on similar shell characters: size, globose shape, inflated reticulate protoconch, number and distinct inflation of the body whorls, and fine, prosocline sculpture of the final body whorl. the fossils occur in carbonate microbialites that formed in seafloor sediments during archaeal anaerobic oxidation of methane in the zone of bacterial sulfate reduction, associated with H2S- and CH4-rich fluid seepage. the California Retiskenea? fossils commonly are found in gregarious clusters, or closely affiliated with thin worm tubes or, in one case, a larger gastropod.These Mesozoic records increase the total known species attributable to this cold-seep endemic genus from two to four. Its spatial and temporal distribution thus may have spanned ~9,000 km around the Pacific Rim from at least ~133 m.y. to the present in 10 subduction-related seep sites from California (possibly Upper Jurassic-Lower Cretaceous), Washington (middle Eocene-Upper Oligocene), and modern offshore Oregon, the eastern Aleutians, and the Japan Trench. If the generic placement of these microgastropod fossils is correct, the California records are the oldest-known occurrences of Retiskenea, consistent with an estimated minimum Mesozoic origin for the 'hot vent' Neomphalidae, as inferred from molecular analyses published on other living members of the family.
