This book provides two state-of-the-art quantitative techniques to
determine ultra-trace rare earth elements (REEs) in natural
carbonates using solution nebulization-inductively coupled plasma
mass spectrometry (SN-ICPMS) and laser ablation-inductively coupled
plasma mass spectrometry (LA-ICPMS) with respective applications
were presented in this dissertation. These techniques were applied
to natural carbonates, including corals and stalagmites, to
understand volcano eruptions and the impacts on modern biosystem
and paleoclimate regimes. In the first SN-ICPMS protocol, direct
measurements for femtogram quantity carbonate samples without
chemical separation steps can offer accurate and high-precision
analysis (+/-1.9-6.5%, 2 ) with a high sample throughput of 8-10
samples/hr routinely. Application to modern Porites corals
collected from South China Sea region, the anomalies of REE
contents and Al/Ca ratios associated with micro-domain images,
register modern coral reefs could be exacerbated by volcanic
eruptions. In the second protocol, a high-sensitivity quantitative
open-cell LA-ICPMS technique has been established to allow direct
sampling on stalagmite surface in the atmospheric air. This
technique improved limits of detection down to sub-ng/g range and
promises analyses of carbonate REE profiles at the single digit
parts-per-billion (ppb) levels. Application to a 15-cm stalagmite
collected from East Timor reveals two peaks of REE contents by at
least one order of magnitude, possibly due to volcanic ash
preserved in stalagmite. Both improved SN-ICPMS and LA-ICPMS
techniques highlight the high-sensitivity and
high-temporal-resolution carbonate REE analyses for corals and
stalagmites, with great potential to other natural carbonates such
as travertine, tufa, and flowstone, benefit our understanding of
paleoclimatic and paleoenvironmental dynamics.
