Notes: * = analyses run through January 21, 1999. Published values and means (parts per million except for TiO₂,which is in weight percent) and standard deviations (in percent) of repeated analyses of the BHVO-1 reference standard following Leg 183 calibration. SD = standard deviation. Trace elements were not recalibrated after mechanical repairs during the leg. † = samples from Sites 1141 and 1142 were analyzed postcruise at The University of Massachusetts. Kilauea 1919-1 is a sample collected from the same flow as BHVO-1 and is used as a standard at The University of Massachusetts. The reported values are the average and standard deviation of three replicate measurements.
