[meteorite-list] Re: Campos Sales

Ola List,

While Senhor Steve is busy spending his disposible income in 
Mexico this week, and being missed by the fan club, which will 
leave him much more enthusiastic about trading or otherwise 
purging his collection of yesterday's treasures when he gets 
back, I had a question not to beat the old horse Campos 
Sales...

A while back some excellent directions to Campos Sales were 
posted on the list for all who were desperately trying to find 
some material from this locality.  I followed those directions 
and ended up in a brachish field:

Campos Sales L5
7°2'S, 40°10'W, 31 January 1991, 22:00 Local Time, A meteorite 
shower fell in a rural area ~18 km E of the village Campos 
Sales found in grainfields around two weeks later.  

Question:  I was wondering how specimens from this fall 
compare to the Kendrapara H4-5 (formerly "Orissa") from 
Kendrapara locality in Orissa, India which fell on 27 Sept. 
2003. "Rusting is conspicuous on the broken surface and may be 
attributed to the wet environment of fall.", according to the 
Meteoritical Society Bulletin for the Indian fall.

As both are Ordinary Chrondrites, and the Kendrapara, Orissa, 
India (H4-5) would seem to be similar in that it is a coastal 
tropical location, and known for salt water intrusion, just 
like the Campos Sales region.  Both are near mangrove 
habitats.   Further, the rainy season starts to peak during 
the quoted recovery time in Campos Sales, and to boot, Campos 
Sales sounds like it means "Salt Fields" in Portuguese.

How stable is most material from Campos Sales, given that 
after only 2 weeks at most for recovery, shouldn't all 
exhibit "jet" black fusion crusts after such a short time?

Saudades do México, Doug
