陨石可划分为球粒陨石及分异的陨石两大类。球粒陨石是由星云形成的,而且从未熔融过,球粒陨石可以看成是太阳星云内的沉积岩.其它主要的陨石类型是由分异的陨石构成的,这些陨石通常是在行星体内导致分异作用的熔融过程形成的.分异陨石是重要的,因为它们提供了有关火成岩分馏作用的过程怎样在行星体内发生而不是在地球内部发生的证据。另一方面,球粒陨石给我们提供了关于古老的太阳星云作用过程的信息,这种作用过程导致形成第一个岩石,并由这些岩石导致形成行星。
Meteorites can be divided into chondrules and separate meteorites two categories. Chondrites are formed by nebulae and never melt, and chondrites can be considered as sedimentary rocks within the solar nebula. Other major types of meteorites are composed of distinct meteorites that are usually caused within the body of the planet Dissimilar meteorites are important because they provide evidence of how the processes of igneous rock fractionation occur within the planet rather than within the Earth. Chondriosomes, on the other hand, provide us with information about the action of ancient solar nebulae, a process that has led to the formation of the first rocks that lead to the formation of planets.
