WORLDKINGS - Worldkings News - Asia Records Institute (ASRI) Lonar Crater: World's largest known basaltic impact crater


( Lonar is among the five largest crater lakes in the world. Though the lake is the most famous one for being the world's largest basaltic impact crater.

Lonar Lake, also known as Lonar crater, is a notified National Geo-heritage Monument, saline, soda lake, located at Lonar in Buldhana district, Maharashtra, India. Lonar Lake is an astrobleme created by a meteorite impact during the Pleistocene Epoch. It is one of only four known hyper-velocity impact craters in basaltic rock anywhere on Earth. The other three basaltic impact structures are in southern Brazil. Lonar Lake has a mean diameter of 1.2 kilometers and is about 137 meters below the crater rim. The meteor crater rim is about 1.8 kilometers in diameter.

Lonar Crater sits inside the Deccan Plateau – a massive plain of volcanic basalt rock created by eruptions some 65 million years ago. Its location in this basalt field suggested to some geologists that it was a volcanic crater. Today, however, Lonar Crater is understood to be the result of a meteorite impact. The water in the lake is both saline and alkaline.

Geologists, ecologists, archaeologists, naturalists and astronomers have published studies on various aspects of the ecosystem of this crater lake.

The water of the lake contains various salts and sodas. During dry weather, when evaporation reduces the water level, large quantities of soda are collected. Two small streams, named Purna and Penganga, drain into the lake, and a well of fresh water is located on the southern side, close to the water's edge.
