(C3-ung in MetBull 80)
Found June 1995
27° 16.03′ N., 16° 25.22′ E. A stone weighing 451 g was found in the Libyan Sahara. It is shocked to stage S1 and has a weathering grade of W1. The Largest fragment of a meteorite, typically at the time of recovery. Meteorites are commonly cut, sliced or sometimes broken thus reducing the size of the main mass and the resulting largest specimen is called the "largest known mass". Click on Term to Read More is at the University of Humboldt in Berlin. A 703 g stone recovered nearby, designated DaG 056, is thought to be paired with DaG 055 based on similar cosmic-ray exposure ages (6.1 and 6.3 m.y. respectively), similar bulk compositions, and their close proximity when found. In 1998, stones were found nearby that might also be paired with DaG 055—DaG 429 (253 g) and DaG 430 (572 g; CRE age of 5.9 m.y.). Notably, only DaG 056 has been found to contain solar-type rare gases indicative of a Mixture of unconsolidated rocky fragments, soil, dust and other fine granular particles blanketing the surface of a body lacking an atmosphere. Regolith is the product of "gardening" by repeated meteorite impacts, and thermal processes (such as repeated heating and cooling cycles). Click on Term to Read More origin. Another type-3 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, NWA 1665, has an O-isotope composition that plots near the DaG 055 pairing group, and it has been suggested that it could also be related.
