“…Moderate ferroan and non-ferroan drusy calcites followed ferroan calcite as they postdated the majority of compaction (cement content is <10% rock volume) and aragonite dissolution. Numerous controls on nucleation and growth of concretions have been proposed (Raiswell 1971;Curtis et al 1972;Dix & Mullins 1987;Carpenter et al 1988); however, a large percentage formed early during organically induced reduction in shallow burial environments (e.g., Irwin et al 1977;Middleton & Nelson 1996). This explanation is consistent with petrographic and isotopic characteristics of early phases of concretionary cements in the Petane Group.…”

“…The unusually heavy carbon isotopic compositions found in the present study -as high as + 13.5%-has also been reported for carbonate minerals by Murata et al (1969), Deuser (1970), Curtis et al (1972), De Giovani et al (1974), and Shidlowski et al (1976 and can be explained only by considering the budget of carbon species in a closed system under anaerobic conditions. Nissenbaum et al (1972) reported heavy carbon isotopic composition (δ 13 C value +17.3‰) for dissolved CO 2 in interstitial water of sediments in a fjord in British Columbia.…”

“…Furthermore, if our assertion is incorrect and there was 339 sufficient organic matter to be remineralized by bacterial sulfate reduction in the sediments, we 340 would expect the decline in δ 13 C to be associated with strong δ 34 S enrichment linked to bacterial 341 sulfate reduction, exactly the opposite of the observed trend (4B, also see below). These 342 observations support primary rather than secondary oolitic carbonate precipitation, thus 343 literature for decades (Curtis et al, 1972;Hudson, 1978;Mozley and Burns, 1993;Coleman, 363 1993); the critical point to the Shuram Excursion is that 13 C-depletion produced via this 364 mechanism is unlikely to affect thick packages of carbonate and oolites and would be 365 petrographically recognizable if it had. 366…”
