38° 32′ N., 100° 13′ W. This brecciated meteoriteWork in progress. A solid natural object reaching a planet’s surface from interplanetary space. Solid portion of a meteoroid that survives its fall to Earth, or some other body. Meteorites are classified as stony meteorites, iron meteorites, and stony-iron meteorites. These groups are further divided according to their mineralogy and Click on Term to Read More was plowed up in Ness County, Kansas and has undergone considerable terrestrial weathering. The 21-pound Kansada stone of 1894 might be another mass of this meteorite. Beeler has been shocked to stage S4 and contains shock veins and melt pockets. The total known weight is 8.64 kg.
In a study of the thermal history of the LL6 Saint-Séverin, Min et al.
(2013) determined the closure temperatures for pristine phosphate grains. The results of this study, along with Pb–Pb and Ar–Ar data, led them to conclude that this LL-group meteorite cooled at a slower rate (2.6°C/m.y.) compared to meteorites from the H chondriteOrdinary chondrites with a high content of free Ni-Fe metal (15-19 vol. %) and attracted easily to a magnet. Their main minerals are olivine (Fa16-20) and the orthopyroxene bronzite (Fs14.5-18.5), earning them their older name of bronzite chondrites. Chondrules average ~0.3 mm in diameter.

(~200 km-diameter) during their late cooling phase, possibly reflecting a comparably larger size for the LL parent body. However, a similar cooling history study conducted on H-group chondritesChondrites are the most common meteorites accounting for ~84% of falls. Chondrites are comprised mostly of Fe- and Mg-bearing silicate minerals (found in both chondrules and fine grained matrix), reduced Fe/Ni metal (found in various states like large blebs, small grains and/or even chondrule rims), and various refractory inclusions (such Click on Term to Read More
by Ganguly et al.
(2013) led them to the conclusion that the H-chondrite parent body likely experienced a collisional disruption and re-accretion rather than a consistently slow cooling like that associated with an ‘onion-shell’ model.
Studies of the orbits of two other LL6 ordinary chondrites, Bensour and Kilabo, conducted by Alexeev et al.
(2009), suggest that these meteorites cross the orbitThe elliptical path of one body around another, typically the path of a small body around a much larger body.
