Hyperfiltration-induced fractionation of carbon isotopes

Geochimica et Cosmochimica Acta, 1987
Hyperfiltration of CaCO3 and NaHCO3 solutions through smectites induces chemical and isotopic fractionation of dissolved inorganic carbon (DIC). Early effluent solutions are enriched in carbonic acid and have DIC concentrations higher than the stock solutions from which they were derived.

Carbon isotope fractionation during photosynthesis

Geochimica et Cosmochimica Acta, 1960
A study was made of the reasons for isotopic fractionation in photosynthesis and the various factors controlling it. CO/sub 2/ samples from plants, air, and calcium carbonate were analyzed in a mass spectrometer in order to determine C/sup 13//C/sup 12/ and O/sup 18//O/sup 16/ ratios.

The carbonate fraction in carbonatitic Italian lamprophyres

Lithos, 2005
Abstract Alkaline and ultramafic lamprophyres represent the majority of pre-Pleistocene alkaline mafic magmatic activity in Italy and have been described from several localities. The age of magmatism ranges from Triassic to Lower Oligocene. Some contain appreciable amounts of carbonate.
