Writeup

Writeup from AMN 26(2):

Sample No.:	MET 01018
Location:	Meteorite Hills
Field No.:	13874
Dimensions (cm):	6.5x5.5x3.5
Weight (g):	222.40
Meteorite Type:	EH3 Chondrite

Macroscopic Description: Kathleen McBride
80% of the sample's exterior has weathered fusion crust with oxidation haloes and polygonal fractures. The interior is weathered with some rust and light colored chondrules (mm sized).

Thin Section (,4) Description: Linda Welzenbach, Tim McCoy
The section shows an aggregate of chondrules (up to 1 mm), chondrule fragments, and pyroxene grains in a matrix of about 30% metal and sulfide. Several chondrules contain olivine. Weathering is modest, with staining of some enstatite grains and minor alteration of metal and sulfides. Microprobe analyses show the olivine is Fa_0-1, orthopyroxene is Fs_0-2 and metal contains ~3.5 wt.% Si. The meteorite is an EH3 chondrite.
