	Lonar crater - Wikipedia, the free encyclopedia
		Lonar crater in the Buldhana district of Maharashtra state, India is the largest crater in basaltic rock.
		Lonar crater is situated around 550 km from Mumbai, 160 km from Aurangabad and 140 km from Buldhana at 19.975° N 76.51° E.
		The impact origin of Lonar Crater is further substantiated by the presence of shatter cones; impact deformation of basalt layers comprising its rim; shocked breccia inside the crater; and a nonvolcanic ejecta blanket surrounding the crater.It is also the world's largest metorite lake.

	Impact crater - Wikipedia, the free encyclopedia
		An impact crater (impact basin, astrobleme or sometimes crater) is a circular or oval depression on a surface, usually referring to a planet, moon, asteroid, or other celestial body, caused by a collision of a smaller body (meteor) with the surface.
		Few underwater craters have been discovered because of the difficulty of surveying the sea floor; the rapid rate of change of the ocean bottom; and the subduction of the ocean floor into the Earth's interior by processes of plate tectonics.
		The distinctive mark of an impact crater is the presence of rock that has undergone shock-metamorphic effects, such as shatter cones, melted rocks, and crystal deformations.

		Though the Lonar crater does not have such an adventurous scientific battle associated with it, the crater itself is an interesting one and has been doubted as a volcanic crater for most of the nineteenth and half of the twentieth century.
		First of all they found that the crater is highly circular in diameter and has a characteristic depth-to diameter ratio of an impact crater.
		The crater is formed in the basalt rock of thickness 600-700m.

	The Role of Volatiles in the Geology and Geomorphology of Impact Craters on Mars II - Planetary Sciences [P]
		Crater collapse simulations carried out with SALEB show that the combination of shock/plastic heating and the structural uplift of initially deeper strata create a water-bearing zone at depths where water is in the liquid stability field.
		Furthermore, the Bond crater is highly degraded and the rim slopes derived from HRSC stereo data vary between 10$^\circ$ to 20$^\circ$ in contrast to the more pristine Hale crater with slopes in the range of 20$^\circ$ to 30$^\circ$.
		The relatively small Lonar crater (1.8 km diameter) is one of only two known terrestrial craters to be emplaced in basaltic target rock [1], and our work has led to a new model for the rock component of the martian soil involving a component of hydrothermally altered basalt [2].

		The ages of the craters are evidently grouped around those "tick-events" of the cosmic clock (to be alternatively understood also as the cosmic quantum jumps) which had resulted in the extraordinarily strong mass extinctions of the living organisms.
		It is one further example of a crater the age of which has been estimated exactly enough for to choose the proper group of the cosmic events but not precisely enough for to decide which one of them was the real event forming the crater.
		It demonstrates that for the smaller craters even some relatively precise observational estimation of the crater age (with an error of only 3 per cent in that case) is sometimes not precise enough for to separate one of the four possible levels of the events of the Cosmic Hierarchy.

	Structural effects of meteorite impact on basalt: Evidence from Lonar crater, India
		Lonar crater is a simple, bowl-shaped, near-circular impact crater in the ∼65 Myr old Deccan Volcanic Province in India.
		As Lonar crater is a rare terrestrial crater formed entirely in basalt, it provides an excellent opportunity to study the impact deformation in target basalt, which is common on the surfaces of other terrestrial planets and their satellites.
		Uplift and tilting of the basalt sequence and formation of the fractures inside the crater are clearly related to the impact event and are different from the preimpact structures such as cooling-related columnar joints and fractures of possible tectonic origin, which are observed outside the crater.

		Craters are not preserved at all well in water, so at the outset we have only just over a quarter of the planet available for cratering.
		As can be seen, it has the bowl shape typical of small craters however, it is squarish in outline rather than being perfectly circular; probably because of pre-existing structural discontinuities in the impactee.
		As an aside, the Canadian Geological Survey does much of their research on these craters in the winter when they can take a drilling rig out onto the ice and the flies are less of a nuisance.

		This crater is a recent impact on the Deccan Trap flood basalts, so it superimposes the two active factors that appear to have caused the end of the dinosaurs and which mark the end of the Cretaceous period.

		Manicouagan, the largest of the five craters, is more than 100 kilometers in diameter, comparable to the 170-kilometer Chixulub crater in the Yucatan–the impact that is believed to have caused the mass extinction at the end of the Cretaceous period 65 million years ago, killing the dinosaurs.

		Lonar Crater, in Maharashtra, is the only known meteorite impact crater on Earth emplaced into basalt target rocks, and the Deccan Trap flood basalt has been labeled as a good analog for Mars basalt as observed from thermal infrared orbital instruments.
		Lonar Crater is a useful place to study such materials that have been naturally-shocked as opposed to the lower shock pressures and recoverable volumes of material associated with laboratory experiments.
		A few other projects Shawn is involved in are detailed field studies of the ~22 impact craters of the Campo del Cielo, Argentina crater field, remote sensing of impact craters on the Earth and Mars, and the processing and analyses of thermal infrared data from the Mini-TES instrument on the Mars Rovers.

		A systematic study later revealed that the glassy material was ``profusely concentrated symmetrically on the east and west sides within a radius of 500 to 600 feet commencing from the middle of the outer slope.

		Though the crater's origin is still being regarded as terrestrial, professors of the Smithsonian Institution, Washington, the GSI and the U.S. Geological Survey in a detailed analysis of the scattered objects in the Lonar Crater are of the view that the crater provides unique opportunities for comparison with lunar samples of ``shocked basalt''.
