Rudjer Bošković Institute radiocarbon measurements XI
This is a list of radiocarbon analyses determined since our previous list (R, 1987, v 29, no. 1, p 135-147). As before, with the exception of speleothems and groundwaters, the calculations follow conventional RADIOCARBON protocol (Stuiver & Polach, 1977). Sample pretreatment, combustion and counting techniques are essentially the same as described in R, 1971, v 13, no. 1, p 135-140, supplemented by new techniques for groundwater processing (R, 1979, v 21, no. 1, p 131-137). Speleothem and groundwater model ages (given in the comment section of each listing) are based on an initial activity of 85 ± 10 percent modern carbon (pMC), as recommended in Srdoc et al (1986), without adjustment for 5'3C. These model ages can be converted from the 5570-yr half-life to the chronometrically more correct half-life of 5730 yr by multiplying by the factor 1.029. The "± figures" on these model ages are statistical combinations of the 1 a counting uncertainty and the ± 10% uncertainty in the assumed 85 pMC. Ages and "± figures" of all other samples are adjusted for stable isotope fractionation according to the recommendations in Stuiver and Polach (1977). Data processing is done by computer (0belic & Planinic, 1977 ; 0belic, 1980). Sample descriptions are prepared in collaboration with collectors and submitters.
