Mineralogia, texturas y cosmoquirmca de condrulos RP y PO en la condrita Reliegos L5 (Leon, España)

Abstract

The chondrite Reliegos, fell in the León Province in 7947, is the last recognized meteorite recovered in Spain. It is a L5 chondrite, with olivines Fa22t2S2, and low Ca pyroxenes En7547e7 Fs20U226. Due to the intense recrystallization it has suffered, ehondrules are rare, and their rims are poorly delineated. However, ehondrules of different types have been identified. Their compositional and textural characteristics are described, together with the elemental distribution inside the ehondrules, by punctual electron microprobe analysis and PIXE profiles
