Description

Description

Les  chondrites ordinaires de type LL  sont un type de  météorite  chondritique . Elles constituent le groupe le plus rare des  chondrites ordinaires , représentant 10 à 11 % des chondrites ordinaires et 8 à 9 % de l’ensemble des météorites cataloguées. On pense que les chondrites proviennent ordinairement de trois astéroïdes corps parents, dont les fragments ont formé respectivement les groupes des  chondrites de type H , de  type L  et de  type LL [ 1 ] . La météorite qui produit le  météore de Tchéliabinsk  est une chondrite de type LL.

Elles contiennent 19 à 22 % de fer total et seulement 0,3 à 3 % de fer métallique. Cela signifie que la majeure partie du fer est présente sous forme d’oxyde de fer (FeO) dans les silicates ; l’olivine contient 26 à 32 mol% de  fayalite  (Fa). Les minéraux les plus abondants sont l’ hypersthène  (un  pyroxène ) et l’ olivine . Les autres minéraux présents sont l’alliage fer-nickel, la  troïlite  (FeS), le  feldspath  ou du verre feldspathique, la  chromite  et des phosphates.
