“…(Fig.12) Either petroleum hy drocarbons or "some combination of a non-hy drocarbon source and a bacterial selectivity during oxidation" was the explanation to the source of the light carbon (RUSSELL et al, 1967). More negative 813C values ranging from -45 to -60%0 were reported from the aragonite and magnesian calcite cement of the Pleistocene sandstone dredg ed from the sea floor off the eastern U.S. coast (HATHAWAY and DEGENS, 1969;ALLEN et al, 1969) (X and A in Fig.12). In this case, the light ness of the carbon was attributed to the 13C_ depleted carbon dioxide derived from microbial or inorganic oxidation of organic or especially methane fermentation of organic material (RosEN FELD and SILVERMAN, 1959;NAKAI, 1960), which resulted in a strong enrichment of 12C.…”

Abstract-Pleistocene calciferous dolomite occurs in association with, besides pyrite and carbonaceous matter, either (1) magnesian calcite, calcite and aragonite, or (2) calcite with or without aragonite, in fossiliferous wackestone of the Naha Limestone in south Okinawa. This difference in mineralogical assemblages depends on the degree of leaching through subaerial weathering, which was witnessed by the systematic difference in Cl , S04 and organic carbon and pyrite contents of the carbonate rocks and by a negative shift of S 13C in the associated calcite.

“…Hence, at depth, the involvement of gas as a fluid and the absence of water may explain the formation and preservation of vaterite. The initial precipitation must have involved conditions of supersaturation; this, in fact, is the basis of the methods by which vaterite has been synthesized (McConneU, 1960 (Lawrence and Taviani, 1988); marine-and seamarginal meteoric carbonates (Friedman, 1964(Friedman, , 1968; hypersaline carbonates (Friedman, 1965;Friedman and Sanders, 1967); deep-burial carbonates (Friedman, 1987a,b and unpublished data); methane-derived carbonates (Allen et al, 1969;Friedman, 1991a;Ritger et al, 1987); spurrite rocks (Kolodny and Gross, 1974).…”

Vaterite, a CaCO3 polymorph, is a rare mineral that is said to be metastable under all known conditions. According to the literature, vaterite precipitated from carbonate solution recrystallizes spontaneously to calcite or aragonite. Yet vaterite has been identified in hard tissues of organisms, in gallstones, in contact metamorphic aureoles, in zones of thermal metamorphism, in a meteorite, and in cone-in-cone concretions. Newly precipitated vaterite has formed at the expense of carbonate rock in drilling fluids in wells of New York, Michigan, Nevada, Texas, and New Zealand. Petrographic examination reveals a light brown core of CaaSiO5 surrounded by a colourless rim of vaterite. The ~lSOpo a of New York vaterite is -12.4%o and that of the Michigan vaterite is -17.67/0o, which reflect the oxygen isotopic composition of meteoric freshwater used in drilling. The ~13CpD B value of --19.27/oo for New York vaterite and that of -17.67/oo for Michigan vaterite suggest that natural gas dissolved original carbonate in the subsurface. Drilling records from both wells indicate that natural gas was released into the drilling muds from the formations exposed at the time vaterite was encountered. Crossplots of the oxygen and carbon isotopic ratios overlap those of spurrite rocks in thermal metamorphic zones in Israel. A C-14 radiocarbon analysis of the Michigan vaterite gave an age of 953 + 39 yr. BP. 88.8__+0.6% is modern carbon and 11.2% is dead carbon. Hence this carbon, and therefore the vaterite, is essentially modern. A sample of the New York vaterite yielded a modern age.
