Lonar Lake is a saline soda water lake located at Lonar in Buldana dist Maharashtra, India, which was created by a meteor impact( during the Pleistocene Epoch). This lake, which lies in a basalt impact structure, it's nature is both saline and alkaline. Geologists, ecologists, archaeologists, naturalists and astronomers have reported several studies on the various aspects of this crater lake ecosystem. Lonar Lake has a mean diameter of 1.2 kilometres and is about 137 metres below the crater rim. The meteor crater rim is about 1.8 kilometres in diam. The circular depression bears a saline water lake in its central portion. The crater's age is usually estimated to be 52,000 ± 6,000 years (Pleistocene), although a study published in 2010 gives an age of 656,000 ± 81,000 years.
The Smithsonian Institution, the United States Geological Survey, Geological Society of India & University of Sagar and the Physical Research Laboratory have conducted extensive studies about the area of crater.
nitrogen fixation:Biological nitrogen fixation was discovered in this lake in 2007.
