EVALUATION OF THE Pa$sup 231$/Th$sup 230$ METHOD AS A GEOCHRONOLOGICAL TOOL FOR THE STUDY OF PELAGIC SEDIMENTS
Technical Report
·
OSTI ID:4631936
An evaluation of the Pa/sup 231/Th/sup 230/ method is being made. Preliminary data indicate that absolute ages for various levels of pelagic sediments are obtained only in rare instances. However, accumulation rates based on the slope of the curve of the exponential change in Th/sup 230//Pa/sup 231/ ratio with depth apparently agree with radiocarbon based accumulation rates. Various assumptions of the method are being tested. Eleven samples of sea water are being processed for their protactinium and isotopic thorium composition. (auth)
