The initial discoveries of elevated Ir and other siderophile element concentrations at the K/T boundary by Alvarez et al.  and Ganapathy  and their interpretation as the signature of a major impact event on Earth has prompted vigorous debate over the nature and cause of the K/T mass extinction event. The wide spectrum of scientists interested in this fundamental problem of Earth-evolution gathered at the conference, Global Catastrophes in Earth History, held in late October 1988 at Snowbird, Utah. Cosponsors were the Lunar and Planetary Institute, Houston, Tex., and the National Academy of Sciences, Washington, D. C.
