Abstract

Abstract : The Middle Jurassic, Dharang Member of the Habo Formation, Habo Dome, Kutch, India yields rich foraminiferal assemblages comprising 59 species. The assemblages are dominated by the families Vaginulinidae and Nodosariidae. This paper is a systematic account of the 22 species recorded for the first time from this region. The foraminiferal assemblages indicate a Callovian age for the studied sequence. Based on the foraminiferal evidence, the sediments of the Dharang Member at Habo Dome were deposited in open marine conditions in the middle to outer shelf, with a fluctuating shoreline and within a tectonically unstable shelf zone. The Dharang Member foraminiferal assemblages, as well as other Jurassic foraminiferal assemblages of Kutch and Rajasthan, are assigned to the Indo-East African Province of the Anti-Boreal Realm.
