(Table 1) Carbon, oxygen and strontium isotopic composition of the rhodochrosite nodules from DSDP Sites 503A and 503B
Listed in DataCite
Calcic rhodochrosite occurs as nodules around burrows in late Neogene-early Pleistocene pelagic sediments of the Galapagos Ridge in the Guatemala Basin, eastern equatorial Pacific (DSDP Leg 68; Site 503).
Description
Growth was accomplished in the suboxic zone (d13C = -4.3 per mil to -1.3 per mil) at an estimated depth between ~30 and 70 cm beneath the seafloor. The rhodochrosites have 87Sr/86Sr ratios (0.708945–0.709073) that largely record the small-scale changes in seawater Sr-isotopic composition.
The anomalous enrichment of the rhodochrosite in 18O isotopes (d18OPDB up to +6.4 per mil is attributed to the dissociation of gas hydrates.
