Abstract
THE relative differences in the ratios oxygen-18 to oxygen-16 and carbon-13 to carbon-12 of some hundred and fifty carbonate rocks, including fourteen sedimentary limestones, ninety metamorphic limestones, twenty ‘intrusive’ carbonatites, twelve calcite crystals from Alpine clefts1 and seven calcareous sinters have been measured. The aim of this investigation, which is being extended to include other carbonate rocks, is the accumulation of data that might lead to an interpretation of the isotopic differentiation in the carbonates on the basis of their geological history.
