The oxygen-isotope ratio ( 0/ 0) found in the calcareous tests has been used as an indicator of the amount of water locked up in glaciers, which reflects the state of the global climate. Another source of continuous records of oxygen-isotope variation, as well as dust content and acidity, is found in the long cores drilled in polar ice caps in which annual layers can be counted and seasonal variation can be established [65]. [Pg.28]

Figure 10.9. Range of oxygen isotope variations of cherts with time. The dots are individual analyses and the upper and lower curves connect, respectively, the highest and lowest 8180 values for cherts at a given time. The 8180 values in cherts can represent the 180/160 ratio and temperature of the waters in which they formed and diagenetic effects. (Modified from Knauth and Lowe, 1978 and Holland, 1984.)...

The zircon reference material 91500 discussed before seems to be very suitable for calibrating in situ oxygen isotope analysis. For example, SIMS was employed to study the 8 0 value on the zircon single crystal 91500 . No systematic differences in SIMS 8 0 data were observed between individual fragments of zircon crystal. Peck et alP studied oxygen isotope ratios by ion microprobe analysis for evidence of oxygen isotope variation in continental crust and oceans in 3.3 to 4.4 X 10 year old zircons. In addition, the authors also analyzed rare earth elements (REEs). ... [Pg.399]

In recent years, we have seen the use of new isotopic systems, including those of osmium and oxygen, in the description of oceanic basalts. Osmium isotopes can trace the addition of mafic crust or melt to the mantle source (Hauri and Hart, 1993) and have been used to highlight the presence of recycled mafic crust in sources of hot spots (Shirey and Walker, 1998). In a complimentary fashion, oxygen isotope variations trace directly... [Pg.1172]

Following Emiliani s (1955) discovery, other laboratories established the capability to apply oxygen isotope variations to oceanic temperature history. It is worth a brief mention of two further major advances relevant to Urey s original conception. In 1967, Nicholas Shackleton of Cambridge University reported the first systematic down-core variations in benthic foraminifera (Shackleton, 1967). He argued that benthic fauna, because they lived in the near-freezing bottomwaters of the ocean, would mainly record... [Pg.3214]
