[meteorite-list] Petrologic types

[Lars Pedersen]

Ho ..... sorry typing error  ...... Hi   I have been thinking - not that I do that very often - What does the petrologic type 3.8 mean ?   I understand the types 3-4-5-6 but when it comes to the decimals I fall off.   Can anyone enlighten me ? (or how it is spelled)   I just bought a NWA 987 L3.8 so I want to know more about it.   Regards Lars
