NWA meteorite probably an object separated from a larger meteor during entry into the earth’s atmosphere. Or on impacting in the western Sahara desert. The stony iron meteorite displays a glassy molten surface, the interior structure can be observed, where surface impact fractures occur.
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.
