Evidence for Relative Sea Level Change from Isotopic and Elemental Composition of Siderite in the Cardium Formation, Rocky Mountain Foothills

Samples of early diagenetic siderite from a single outcrop section of the Cardium Formation (Turonian-Coniacian) in the northern Rocky Mountain Foothills have been analyzed to determine whether trends exist in their oxygen isotopic and elemental compositions, and whether such parameters can be used to detect relative sea level changes. We found that vertical trends generally match those predicted based on the sedimentology and stratigraphy of...
