Chondrite Meteorite L5-6 S3 W3

BE 1058

After having obtained all the analytical data, and after having carefully evaluated them, taking

Into account the geological and meteorite standards mentioned in references, the the analysed sample is identified as L-chondrite meteorite, obtaining MgO/MnO ratios in this chemical group.

Petrography; The sample shows chondritic texture, and it is composed of recognizable chondrules up to 0.7 =- 0.5 mm (n=15) in diameter, chondrule fragments and mineral clasts. The matrix ( 35 vol%)

Is composed of compacted fine dust. Olivine is zoned, with undulatory extinction and irregular fractures. Pyroxene shows exsolution. Metallic phased occupied 12vol%, and it is composed of FeNi

(kamacite sand minor taenite), granular. Accessory is troilite and opaques

For all these reasons, the analysed sample for their characterizations and analysis have yielded

POSITIVE results in its compatibility for meteorites, being in this case, an ordinary chondrite,

Type L5-6 (based on XRF data, diameter of chondrules and Fe content), with a shock degree S3 (based on planar deformation and irregular fractures in silicates) and with a weathering degree W3 (based on iron oxidation and silicates alteration.
