Scientists hope that if microbes lived in or around this body of water, signatures of their presence will be retained in sediments that can be easily drilled today. A key target will be the carbonate deposits that seem to line what would have been the palaeo-lake's shoreline. "Carbonates are a type of mineral that precipitates out of water and what's really great about that process is that when they precipitate out - they trap everything that's in the water. So, everything that's living there can be trapped inside the mineral," explained Briony Horgan from Purdue University in Indiana. http://www.jonniphilips.com/city-guides/durbansouth.html
