Sample No.:

GRO95626

Location:

Grosvenor Mountains

Dimensions (cm):

5.5x3.0x2.0

Weight (g):

52.2

Meteorite Type:

EL6 Chondrite


Macroscopic Description: Carol Schwarz
This chondrite has thin, remnant, iridescent fusion crust on about 50% of the exterior surface. The interior is dark red brown and contains some evaporate deposits. The specimen is very co-herent because of its high metal content. Several deep fractures pene-trate this meteorite. There are no clasts or chondrules visible on the interior.

Thin Section (,2) Description: Brian Mason
GRO95626 - Cross-Polarized LightOnly vague traces of chondritic structure are visible in the thin section, which shows the meteorite to consist largely of prismatic or granular enstatite (grain size 0.1-0.2 mm), a considerable amount of nickel-iron, and minor amounts of sulfides and plagioclase. The meteorite is considerably weathered, with brown limonitic staining throughout the section. Microprobe analyses show that the enstatite is almost pure MgSiO3 (FeO 0.2-0.5%); one grain of plagioclase, An17, was analyzed; the nickel-iron contains 0.9-1.0% Si. The meteorite is an EL6 chondrite.
