Found March 24, 1997
27° 21.74′ N., 16° 05.38′ E. Two fragments of this formerly Karoonda-type Carbonaceous chondrites represent the most primitive rock samples of our solar system. This rare (less than 5% of all meteorite falls) class of meteorites are a time capsule from the earliest days in the formation of our solar system. They are divided into the following compositional groups that, other than Click on Term to Read More were found in the Libyan Sahara weighing a total of 492 g. Dar al Gani 275 has been weakly shocked to stage S2, and has been highly weathered to grade W4 on the Wlotzka weathering scale (1993). Another similar Work 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 of Measure of the degree of aqueous alteration (Types 1 and 2) and thermal metamorphism (Types 3-6) experienced by a chondritic meteorite. Type 3 chondrites are further subdivided into 3.0 through 3.9 subtypes. 4/5, DaG 250, was also found in the Sahara. However, DaG 275 has a different cosmic-ray Time interval that a meteoroid was an independent body in space. In other words, the time between when a meteoroid was broken off its parent body and its arrival on Earth as a meteorite - also known simply as the "exposure age." It can be estimated from the observed effects Click on Term to Read More (35.2 m.y.) compared to DaG 250 (27 m.y.), and the Element occurring in the right-most column of the periodic table; also called "inert" gases. In these gases, the outer electron shell is completely filled, making them very unreactive. Click on Term to Read More data do not exclude separate parent bodies.
