Following neutron activation, a study was made with the Iridium Coincidence Spectrometer (ICS) of the abundance profile of iridium in the Cretaceous-Tertiary boundary region of cores from Hole 752B taken from the Indian Ocean west of Australia. The ICS was modified to measure 13 other elements simultaneously with the Ir determination, and data are included for Co, Cr, Cs, Fe, Hf, and Se. The K-T region was sampled continuously in 1 cm increments from 8...
