description Lonar Overview
The Lonar crater is a unique impact structure located in Maharashtra, India. Formed during the Pleistocene epoch, it’s notable for its unusual circular shape and composition including layers of basalt and limestone. Scientists study this small crater to understand ancient meteorite impacts and geological processes. It's of interest to geologists, planetary scientists, and those researching prehistoric Earth formations.
help Lonar FAQ
How do scientists know Lonar is an impact crater rather than a volcanic crater?
Researchers found shock-altered material, impact breccia, and deformation in the surrounding Deccan basalt. Evidence including maskelynite helped overturn the older volcanic explanation.
How large is the Lonar crater?
The crater rim is approximately 1.8 kilometers across and the depression is about 150 meters deep. The lake occupying its floor is smaller, with a mean diameter of roughly 1.2 kilometers.
Why is the water in Lonar Lake unusual?
Lonar is a saline and alkaline crater lake within the basalt of Maharashtra's Deccan Traps. Its chemistry and microbial ecosystem attract ecologists as well as impact geologists.
How old is the Lonar impact crater?
Published age estimates have varied considerably, which is why older descriptions can conflict. Modern work commonly places the impact at around 50,000 years ago, while some earlier research proposed a much older Pleistocene age.
