Assessing cementation in the El Capitan Reef Complex and Lincolnshire Limestone using ^(13)C-^(18)O bond abundances in carbonates

Abstract

The Permian El Capitan and Jurassic Lincolnshire limestones have been intensely studied for their stratigraphy, depositional setting and paleoecology. Nevertheless, the diagenetic development of these two units remains controversial, particularly with regard to diagenetic carbonate formation. Calcite cement phases have previously been characterized via δ^(18)O and δ^(13)C in order to determine precipitation temperatures and carbon sources, however, these results have lead to conflicting hypotheses
