Abstract

An iridium anomaly was detected in Sample 516F-89-5, 16-36.5cm. The maximum Ir abundance was 0.95 +- 0.18 ppb in 516F-89-5, 33.0-33.5cm. In 23 measurements of the background in a region extending from 43m above the anomaly to 48m below, no Ir was detected. Thus, this region of the South Atlantic does demonstrate a definite Ir anomaly associated with the Cretaceous/Tertiary boundary region.-from Author
