Gosh Mark, I would never pick on your collection like that.
But, like you, I've had my suspicions about a few of the closely related west Texas meteorites.
I've wondered just how accurate some of the lab results/ analyses have been when it comes
to the very minor differences in petrology found in some of the geographically close (as well as
petrographically close) finds here in this vast wonderland known as west Texas.
No, let me restate that... I'm not really questioning the "accuracy" of the results of different labs,
but since each lab has its own unique set of equipment (ie. microprobe, chromatograph, cross
light polararizers, etc., -well, I'm beginning to show my ignorance here since I'm not at all sure
what equipment a typical 'meteorite lab' would have and I barely have an inkling of how it works
and to what end) then it would seem (to an under-educated desert bumpkin such as myself) that
there is probably a mixture of different brands, ages, and types of gear in those diverse labs.
And, unless I miss my guess, each of those different pieces of equipment has its own method and
criteria for calibration. To me, it just seems logical that there would be a slight built-in skewing
and difference of the petrological results that any particular lab would report for any given
meteorite in comparison to the results that a different lab might report on exactly the same piece
of a specimen being tested.
I hope you can devise some sense of what I'm trying to say from the above mess.
Which brings to mind an idea for the Tucson Show. I would love to be wandering down the aisles
and rows there and stumble upon an exhibit titled "Typical Meteorite Lab (and How It Works.)
They would have to drive me off with a stick at closing time.
But back to my supposition... did I make a fair assumption concerning different brands or ages
of the various pieces of testing equipment giving minute differences in results?

Hello Rob and list,
Rob noted, "By next year's Bulletin, California's published total will probably
exceed that of Kansas."
That is of course not accounting for paired finds. New Mexico really doesn't have over 200 meteorites either, and I am sure I am not the only one that would like to see a large scale pairing project done on west Texas meteorites.
Lets number every Brenham and then talk numbers...:-)
