Chondrule Collection

The Murchison CM2 carbonaceous chondrite
Murchison fell in September 1969, in Victoria, Australia. It is rich in indigenous (i.e. not terrestrial contaminant) amino acids and other organic molecules

The Beardsley H5 ordinary chondrite
Beardsley fell in Kansas, U.S.A in 1929. Its fine-grained texture, with poor chondrule resolution indicate that it has experienced thermal metamorphism

The Abee EH4 enstatite chondrite
Abee fell in Canada in 1953. The cut surface clearly shows the metal-rich and brecciated texture of Abee

Vigarano CV3 chondrite
This carbonaceous chondrite meteorite fell in Italy in 1910. It has clearly delineated chondrules or small granules

Parnallee LL3. 6 ordinary chondrite
Parnallee fell in India in 1857. The cut surface clearly shows well-delineated chondrules and slightly larger clasts

Brownfield (1973) H3. 7 ordinary chondrite
This meteorite fell in Texas in 1937. It has very small chondrules, plus highly-reflective metal and sulphide grains can easily be picked out

Microscope image of chondrite showing chondrules, typical of primitive meteorites. Horizontal field of view, 3.3mm

Optical microscope image of the Barwell (Type 6) chondrite. This meteorite has experienced a significant amount of heating

Optical microscope image of the Parnallee (Type 3) chondrite
An optical microscope image of the Parnallee (Type 3) chondrite that has experienced little heating. The chondrules are clear and well-defined. The field of view is 5mm

The Parnalle ordinary chondrite
The Parnallee ordinary chondrite, part of the Parnallee meteorite that fell in India in 1857

The Barwell meteorite, showing a rock frgament formed by melting of a pre-existing planetary body; this indicates that plantesimals were present when chondrules formed

Textures of different chondrule types in the Etihudna (L4) ordinary chondrite (field of view 4mm)

Porphyritic olivine and pyroxene chondrule
Microscopic image of a porphyritic olivine and pyroxene chondrule from the Palmyra (L3) ordinary chondrite (the chondrule is about 1.8mm across)

Radial pyroxene chondrule
Microscope image of a radial pyroxene chondrule from the ALH 88036 (H3.4) ordinary chondrite. The chondrule is about 2mm across

Ivuna meteorite
The Ivuna carbonaceous chondrite. This type of meteorite is the richest in volatile elements

Barred olivine chondrule from the Palmyra ordinary chondrite (the chondrule is about 1.2mm across)
