(See Riggs, et al., \n1994.) The walls of this subaqueous cavern are coated with dense vein \ncalcite which provides an ideal material for precise uranium-series \ndating via thermal ionization mass spectrometry (TIMS). Devils Hole \nCore DH-11 is a 36-cm-long core of vein calcite from which we obtained \nan approximately 500,000-year-long continuous record of paleotemperature \nand other climatic proxies. Data from this core were recently used by \nWinograd and others (1997) to discuss the length and stability of the \nlast four interglaciations. These data are given in table 1.\n\nCarbon and oxygen stable isotopic ratios were measured on 285 samples\ncut at regular intervals inward from the free face of the core \n(as reported in Winograd et al., 1992, and in Coplen et al., 1994). \nTable 1 lists only 284 samples because a sample taken at 114.28 mm was\neliminated when post-1994 reanalysis of its delta 18O value indicated\nan error in the earlier determination. Carbon isotopic ratios are\nreported in per mill (footnote #1) relative to VPDB, defined by\nassigning a delta13C of +1.95 per mill to the reference material NBS\n19 calcite. Oxygen isotopic ratios are reported relative to VSMOW\nreference water on a scale normalized such that SLAP reference water \nis -55.5 per mill relative to VSMOW reference water. The oxygen isotopic\nfractionation factors employed in this determination are those listed in\nCoplen and others (1983). The delta 18O value of the isotopic reference \nmaterial NBS 19 on this scale is +28.65 per mill. The ± 1 sd (standard \ndeviation) error for the delta 18O and delta 13C analyses is ±0.07 \nand 0.05 per mill, respectively.\n\nAges were estimated by linear interpolation between age control points\ntaken at key intervals in the core and analyzed by TIMS 230Th-234U-238U\ndating. The age estimates in Table 1 are based on the original 21 control \npoints (see Table 2 in Ludwig, et al., 1992, and Figure 2 in Winograd, \net al., 1992) as well as for the recently obtained TIMS age of \n143.8±0.9 ka (2 sd analytical error) at 51.5 mm (Winograd, et al., 1997). \nThe later sample was taken specifically for additional control in a \ncritical portion of the core. Errors in the ages vary but are bounded\nby the errors in the appropriate control points. (See Table 2 in Ludwig,\net al., 1992.) \n\nFootnote #1. For expressing isotopic results, we use the spelling \n\"per mill\" as recommended by the International Organization for\nStandardization (ISO, 1992). \n\n","version":"1.0","xmlId":"10906"}
