The famous meteoritic impact—the Chicxulub event (considered responsible for dinosaur extinction), took place 64 million years ago at the eastern coast of Mexico. Around 50000 years ago a massive meteorite moving with velocity of 90000 kmph hit the earth which led to formation of this crater which has a diameter of around 2 k.m. Lonar Lake has a mean diameter of 1.2 kilometres (3,900 ft) and is about 137 metres (449 ft) below the crater rim.

The meteor crater rim is about 1.8 kilometres (5,900 ft) in diameter. Lonar Crater sits inside the Deccan Plateau – a massive plain of volcanic basalt rock created by eruptions some 65 million years ago.

Again, no evidence of meteoric fragments ... endstream Lonar crater, India, is one of the youngest and best preserved impact structures on Earth. The Lonar impact structure is marked by a 135 m deep near circular depression, which is the impact crater. It forms a 1.88 km diameter depression in the Deccan Basalts in eastern Maharashtra near the town of Aurangabad about 8-9 hours drive from Pune. <> <> � �T� The diameter is 1852 meters. � ��� Wildlife Attractions: Langoors, Snakes, Monitor Lizards, Mongoose, Fox … Biological Nitrogen fixation, a process by which nitrogen in the atmosphere is converted into ammonia, takes place in this crater. The 1.88-km-diameter simple crater formed entirely within the Deccan traps, making it a useful analogue for small craters on the basaltic surfaces of the other terrestrial planets and the Moon. The Lonar crater was recognised as a National Geological Monument way back in 1979 by Geological Survey of India. <> Fig. Lonar Lake was created by an asteroid collision with earth impact during the Pleistocene Epoch. Several dozen impact glasses from Lonar Crater, in Maharashtra, India, were analyzed for evidence of impact-generated paleofields, and possible motional remanent magnetization. <> 39 0 obj Abstract–The 50,000 year old, 1.8 km diameter Lonar crater is one of only two known terrestrial craters to be emplaced in basaltic target rock (the 65 million year old Deccan Traps). 2. stream x�3R��2�35W(�*T0P�R0T(�Y@���@QC= P A�J��� �1Tp�W� stream endobj Measuring almost exactly 2.0 km from rim to rim, the crater is partially filled by a salty, alkaline lake 1,200 meters in diameter. <>>>] Presently they are under the protection of Archaeological Survey of India. Lonar Crater sits inside the Deccan Plateau—a massive plain of volcanic basalt rock leftover from eruptions some 65 million years ago.

Masaitis (1989) prefers an evaporation-dominated process and believes that the small size of Lonar crater would not ... Its location in this basalt field suggested to some geologists that it was a volcanic crater. Found inside – Page 284At Lonar Crater, minute amounts of a chondritic impactor have been identified within impact melt spherules (e.g. Misra ...
