Calcium isotope constraints on the marine carbon cycle and CaCO3 deposition during the late Silurian (Ludfordian) positive 13-C excursion
Original language description
This study investigates calcium isotope variations 44 40Ca in late Silurian marine carbonates deposited in the Prague Basin Czech Republic which records one of the largest positive carbon isotope excursion of the entire Phanerozoic higher up in the section where 13Cshifts back to pre excursion baseline values there is a correlated shift to higher 44 40Cavalues. Kinetic processes are integral to the model of rapid carbonate precipitation recently proposed by Kozlowski 2015 to explain the origin of the mid Ludfordian CIE involving intense methanogenesis photosynthesis in near shore settings coupled with rapid CaCO3precipitation and eustatically controlled carbonate hypersaturationof seawater. More Ca isotope studies are needed to shed light on the question of whether kineticsor mineralogycontrols the coupled variations in carbonate 44 40Caand 13Crecords observed in this study and other large positive CIEs in geological record.
