The origin of the Lonar Crater in Maharashtra, India, has been attributed by various workers to volcanic explosions, to cryptovolcanic activity, or to the impact and explosion of a meteorite. Meteoritic material characteristically contains much more nickel and cobalt than do basalts, and, if present in the vicinity of the Lonar Crater, might be expected to enrich the terrain in those elements. The nickel and cobalt content of soils, plants, lake sediment and brines, and spring water collected within the crater showed no perceptible difference from that of similar material collected at a distance of 10 km from the crater. This suggests that the crater is not meteoritic.
