[meteorite-list] Meteorites Australia Classification List Updated

[Jeff Kuyken]

Ahh... it seems you are correct Jeff.

The table lists GRO 021579 as a CO4 but on checking the separate entry it is
indeed listed as CO3. Oh well... back to re-editing the lists! ;-)

Thanks,

Jeff

----------------------------------------------------------
Grove Mountains 021579 72°57'55"S, 75°12'55"E
Antarctica
Found 2003
Carbonaceous chondrite (CO3)
The fragment weighs 6.57 g, with a few remains of fusion crust.
Classification and mineralogy (CAS): Chondrules are small and have a bimodal
size distribution, with one peak at 30-100 µm and the other at 350-600 µm in
diameter. Modal abundance ratio of chondrule to opaque matrix is 1.2. Fe-Ni
metal and sulphide are rare. Ca-Al-rich inclusions were found, and they are
strongly altered. Silicates are highly heterogeneous: olivine, Fa18.8±20;
low- Ca pyroxene, Fs7.0±12. Shock stage, S1; weathering grade, W1.

Looks like you found a typo!  It's not type 4, that's certain from the
description.
