   SAN ANGELOS OCTAHEDRITE

   San Angelos, Texas, USA 

   A slice of iron meteorite showing character-

    istic Widmanstätten pattern. Widmanstätten

    patterns are intergrowths of nickel-rich taenite

    and nickel-poor kamacite.

   IMILAC PALLASITE

   Atacama Desert, Atacama, Chile 

   A slice of stony-iron meteorite showing

   olivine crystal sections imbedded in an iron-

   nickel groundmass with a Widmanstätten

   pattern

   Specimen size: approx. 6.3 cm  X  4.2 cm  X  0.5 cm        Weight: 46.5 grams

   MM003

   BRAUNAU HEXAHEDRITE

   Trutnov, Czechoslovakia

   A slice of iron meteorite showing fine,

   parallel Neumann lines often displayed by

   hexahedrites. Neumann lines apparently

   indicate shock-induced defornation of the

   nickel-iron minerals that form the meteorite.

   Specimen size: approx. 3.5 cm  X  1.7 cm  X  0.4 cm        Weight: 10.5 grams

   GLORIETA MOUNTAIN

   PALLASITE

   Santa Fe County, New Mexico, USA 

   A slice of stony-iron meteorite showing

    olivine crystal sections imbedded in a

    nickel-iron matrix. The metal in this pallasite

    has an unusual elemental composition for

    pallasites.

   (Please disregard the reflections in the iron)

   Specimen size: approx. 9.1 cm  X  8.5 cm  X  0.2 cm        Weight: 70.5 grams

   CAPE YORK OCTAHEDRITE

   West Greenland

   This slice is from one of several iron meteor-

    ites from Melville Bay, Greenland. It shows

    a typical Widmanstätten pattern and troilite

    (iron sulfide) inclusions. Used as a source of

    iron for tools by the local Inuit people, the

    meteorites were rediscovered by Robert

    Peary and transported to New York after much effort.

    Specimen size: approx. 13.6 cm  X  7.8 cm  X  0.3 cm        Weight: 277.5 grams

   MM008

   PORTALES VALLEY METAL

   RICH CHONDRITE

   Roosevelt County, New Mexico,

   USA

   A slice of the very unusual Portales Valley

   chondrite. The mixture of stone and metal

   has some very unique features which offer

   conflicting evidence as to the origin of this stone.

   Specimen size: approx. 9 cm  X  6.5 cm  X  0.6 cm        Weight: 108.5 grams

    MM009

    ESTHERVILLE MESOSIDERITE

   Emmet County, Iowa, USA

    A slice of the brecciated silicate and iron

     Estherville mesosiderite.

    Specimen size: approx. 11.8 cm  X  9.1 cm  X  0.6 cm        Weight: 173.5 grams

   MM010

   TUCSON RING ATAXITE

   Tucson, Pima County, Arizona, USA

   This small slice is from a large ring-shaped

    meteorite first discovered in Sonora, Mexico

    by Jesuit missionaries. The meteorite was left

    near Tucson while being transported to Spain.

    It was taken to Tucson, where it was used as

    a public anvil until it was claimed and donated

    to the Smithsonian. This is an example of a

    rare variety of iron meteorite consisting almost entirely of taenite, a solid solution of iron and nickel rich in iron.

    Specimen size: approx. 3.5 cm  X  1.2 cm  X  0.2 cm        Weight: 5 grams
