This article comprises extracts from a presentation given by Dr Sharad Master entitled "Umm al Binni lake, a possible Holocene impact structure in the marshes of southern Iraq: Geological evidence for its age, and implications for Bronze-age Mesopotamia". This was presented at a conference entitled Environmental Catastrophes and Recoveries in the Holocene, organised by Prof. Suzanne Leroy and Dr Iain Stewart, held from August 29 - September 2, 2002 at the Department of Geography & Earth Sciences, Brunel University, Uxbridge, United Kingdom. A near circular, vaguely polygonal, approx 3.4 km-diameter postulated impact structure in the Al 'Amarah marshes in southern Iraq, has now been identified as the Umm al Binni lake. The lake appears as a light coloured area in recent Landsat TM and SPOT satellite imagery, due to surface salt encrustations, and has shrunk as a result of partial draining of the marshes in 1993.
