Named in honor of Victor A. Gostin, geologist on the faculty of the University of Adelaide, South Australia. A specialist in sedimentology and stratigraphy, Gostin discovered in the Flinders Ranges of South Australia a deposit of shocked debris ejected from the Lake Acraman impact structure about 300 km to the west. His careful studies of this ancient deposit have provided the first detailed picture of the distant ejecta from a known large terrestrial impact crater. (M 12808) _ _.
