Writeup

Writeup from AMN 26(2):

Sample No.:	MET 01017
Location:	Meteorite Hills
Field No.:	13814
Dimensions (cm):	7.5x5.0x3.5
Weight (g):	238.000
Meteorite Type:	CR2 Chondrite

Macroscopic Description: Kathleen McBride
50% of the exterior has weathered fusion crust with oxidation haloes and polygonal fractures. The interior is very fractured and weathered. It is friable with an abundant amount of rust. Some light colored mm-sized condrules are visible.

Thin Section (,2) Description: Tim McCoy, Linda Welzenbach
The section exhibits large (up to 2 mm), well-defined, metal-rich chondrules and CAI's in a dark matrix of FeO-rich phyllosilicate. Weathering is extensive, with staining, patches and veins of hydrated iron oxide. Silicates are unequilibrated; olivines range from Fa_3-19 and pyroxenes from Fs_2-26. The meteorite is a CR2 chondrite.

Writeup from AMN 33(1):

MET 01017 original classification in AMN 26, no. 2, as a CR2 chondrite, but several studies have brought information to light that is inconsistent with that classification. Raman data, as well as isotopic data for C, H, and O indicate this meteorite is not a CR2, but a CV3 (possibly reduced) chondrite [1]. Because the type of CV3 is not clear, and it has anomalous properties, we will reclassify it as CV3 an.
