• Resumen

  • The mineralogical and textural features of the Nulles meteorite are studied by optical microscopy, SEM, and electrone microprobe. Olivine and plagioclase are the main primary phases of the silicate minerals, with the subsequent formation of epidote, from the oligoclase. The metallic phase consists of kamacite, taenite and troi/ite, with variable proportions of their Fe and Ni contents. The main textures reflect, apart of deformation, the existence of chondrules, intergrowths and seudomorphisms.
