2021 Fall Date Project

The MPOD Caretakers want to present meteorite falls on their fall dates. For example, Sikhote Aline on 12 February.

This Project will not dip into the MPOD archives so the Caretakers will appreciate anything you can contribute.

To reserve a date just let us know. Thank you in advance :)

Photos 4 - 6 are thin sections between crossed polarizers, in plane polarized light, and in reflective light.

Photo 7 is an animated GIF of the three.

Macroscopic Descriptionby Roberta Score:
LEW85305 has a rectangular shape and is completely covered with shiny fusion crust. Flow marks are apparent in the fusion crust. The interior has a granular texture, plagioclase is evenly disseminated throughout the brownish matrix.

Thin Section (,4) Description by Brian Mason:
The section shows a granular aggregate of pale brown pyroxene and colorless pyroxene, with accessory opaques; a small amount of an SiO2 polymorph, probably tridymite, is present. The meteorite is unbrecciated, but the pyroxene grains (and to a lesser extent the plagioclase) are considerably granulated. Microprobe analyses show pyroxene compositions ranging almost continuously from Wo6Fs57 to Wo37Fs31, with fairly uniform En content. Plagioclase composition is An84-88. The meteorite is an eucrite; it resembles Ibitira in texture and mineral compositions.
