RE: "akaganeite"?

Hello Gregory,

Give the auctioneer credit for "Truth in Advertising"!

To a mineralogist akaganeite is beta-FeO(OH,Cl), a member of the limonite
family that includes goethite, lepidocrocite, and maghemite.  To a meteorite
collector it means the beginning of the end for an iron meteorite.

Akaganeite has been implicated of being, if not the actual culprit, then at
least the carrier of the chlorine ion involved in the run-away,
rust-producing reaction popularly known as "Lawrencite Disease".

"Oh boy!  Not only do I get a Nan Tan meteorite, but I get a RARE mineral on
top of it - akaganeite!  Lucky me."

He says, tongue-in-cheek,
Bob V.

<<  here are a few grams of Nan Tan meteorite with akaganeite stains 
     on top! RARE!!!! >>

....found in a description of a meteorite for sale on everyone's favorite
internet auction site.  Unfamiliar with this term, can anyone take a stab
at "akaganeite" for me?       Gregory
