Abstract
This paper describes and figures Mesozoic Radiolaria from cherts in Pu lau Ungar, Tanimbar Islands, eastern Indonesia. Two assemblages of Rad iolaria are recognised. The lower assemblage is indicative of upper Ti thonian (uppermost Jurassic) to Berriasian (lowermost Cretaceous) and the upper assemblage is of upper Valanginian to Barremian age. These a re the first precise ages obtained from the Ungar Formation, a unit in cluding sandstones with apparently good petroleum reservoir characteri stics. Copyright (C) 1996 Elsevier Science Ltd
