Carbonates

Carbon & oxygen isotope ratios of carbonate

δ13CCO3 & δ18OCO3

Carbonate stable isotope ratio analysis is a classic measurement in Earth and Ocean Sciences and is a specialty of UCSC SiL. Sample types include foraminifera and other fossils, sedimentary rocks, teeth and bones, otoliths, and speleothem. UCSC SiL measures >30 carbonate samples daily. The carbonate sample measurement rate is $13.00 for UC and affiliates or $20.02 for non-affiliates.

Guidelines for preparing carbonate samples including documenting, packaging, and shipping samples to UCSC SiL for analysis.
