NWA L5 meteorite 33 grams separated from a more substantial meteor on entry to the earth’s atmosphere. Formed from molten particles of the solar nebula, by accumulation or coalescence, particles merge to form asteroid belts which in turn fall to the earth as meteorites.
It is thought the origin of the L chondrite meteorites are former debris of 433 Eros the near-Earth asteroid which has undergone an intense study by the spacecraft NEAR-Shoemaker recently. The reflectance spectra of this body and the L chondrites on earth appear to be consistent. However, most L chondrites exhibit severe shock metamorphism suggesting a violent history of its parent body. It is also then theorised a parent of the L chondrites, perhaps a relative object or a former part of 433 Eros has been disrupted when colliding with another asteroid.
The Chondrite meteorites contain chondrules, these are microscopic spheres which are reputedly the building blocks of our planetary systems. Chondrites by repute originate from asteroids orbiting our solar system. Science can identify Chondrite meteorites which contain up to approximately 20% of iron and nickel, these minute iron and nickel sized spherical mineralised chondrules are often found in iron chondrites.
These Chondrules are formed from molten particles of the solar nebula, by accumulation or coalescence, particles merge together to form asteroid belts which in turn fall to earth as meteorites. These Chondrites differ from iron meteorites due to their low iron content. Most importantly chondrites offer a greater understanding, allowing scientists to further analyse and give great insight into the age of our solar system.
