原始语种摘要: Abstract(#br)This work addresses the potential utility of in situ carbon and oxygen isotope microanalysis (δ 13 C and δ 18 O) by secondary ion mass spectrometry (SIMS) in carbon sequestration research. A desirable long-term consequence of CO 2 -injection into underground rock formations at prospective sequestration sites (such as deep saline sandstone aquifers capped by impermeable strata) is the precipitation of carbonate mineral cements, the isotopic fingerprinting of which is a central theme here. More specifically, we focus on the unique advantage of the SIMS technique, which lies in the capability of analyzing very small sample volumes that are otherwise inaccessible to sampling techniques in conventional isotope ratio mass spectrometry (IRMS). For example, single carbonate...
