OXYGEN AND CARBON ISOTOPIC COMPOSITIONS OF STRATA-BOUND SIDERITES AND THEIR GENETIC SIGNIFICANCES

Wang Guanyu; Chen Chengye

Siderite is a common carbonate mineral, other than calcite and dolomite, wide- 1y appearing as beds or lenses in strata of all ages from the Preca m brian to the Cenozoic.The δ¹³C and δ¹⁸o in siderite reflect the isotopic composition of CO₂ and w aters from which siderite is precipitated and can be used as environ mental indi- cators.
