[meteorite-list] NWA 6292 (BRA) IS paired to NWA 5400 !

[Martin Altmann]

Corrrrrrrrrrrrect, Adam!

In the Bulletins you have often with the classics either tkw figures from
the first (single) report or from oooold literature.
The Blue Book, what has it for Sikhote - 27 tons.
But rather 100 tons were recovered.
Same with Campo, same with Canyon, same with Gibeon....

Gao-Guenie, there was always given 100kg,
but I guess alone Carion must have collected 500kgs.

It took decades until Neuvo Mercurio wasn't listed anymore with 5 but with
50kg.

Also with small-tkw falls.
Remember the example here on the list, where we all found for Chiang Khan
rather 10kgs than the 367g from the Catalogue.

...and so on.

Huh and the rareness of NWAs,
Of course, there seem to be soooooooooooooo much and many.
But that impression is deceptive.

Example, take the NWA 2975-Martian-group.
It has now already 15 different numbers and of course one saw many samples
from these numbers offered,
so that some thought, it must be a mass-Martian, simply because of its
temporary presence on web.
Count together the tkws -   1.3kg.   A little bag full, a nothing.
If you want, add some non-classifed, selfpaired samples,  still a small bag
and a nothing.

There never was Ali Baba's treasure cave in NWA-wonderland.

Just check it, how much smaller the tkws of the NWAs are than those of the
historics, how few of the rarer classes really there are.
It's such a fine tool, the database:
http://tin.er.usgs.gov/meteor/index.php

There are no myriads of tons.

In fact - rareness - historics:

9 of 10 meteorites on Earth belong to the 20 largest mass irons.
(In fact more, cause there the dark figure is highest)

19 CV3s out of 20 are an Allende

3 out of 4 eucrites are a Millbillillie

And so on.

NWAs, the rarer classes are indeeeeeed superrare.

And the rarest of them, these stones with a small tkw.

In a few years/decades they will be legends.

Best!
