Hello Carl,


If you have links to XRF test result data on meteorites, can you
please provide them to me?

Thank you

In my mind I thought I could easily use this chemical data to compare my data with known meteorites and determine based on like chemistry what I might have. This way no scientist is bothered by me until I had something to show them.

> My madness was based on the fact that nearly all if not all rare meteorites that are classified as a particular classification are plotted on little charts and graphs to show that they plot with other known material of the same classification. And states the case that since known meteorite "A" plots in all of these areas and meteorite "B" plots right with them, then it too is the same classification. I know O tests are also needed but that is not in question here.

> This because I ended up having several rocks with the correct chemistry to plot EXACTLY ?on the Mars and Lunar charts right with the known meteorites. (to add to this confusion, there are also known meteorites that do not plot perfectly on these charts ?so, they are simply left off the chart but, acknowledged with a different color plot mark.).
> I thought this would be an easy home test. Simply go to Randy's site and copy all of his amazing charts and plot your results directly onto the same charts he provided. If they plot with Randy's plots then , they are from the moon. Go to a number of other sites and print out these same charts from Mars and plot your results right with theirs.
> This method actually worked out for Calcalong Creek. The first Lunar found outside of Antarctica.
> Bonyton, Hill and Haag saw a meteorite that looked Lunar so, they broke down it's chemistry and determined that since it's ratios were similar to the known moon's ratios. (yes, there were also like minerals) ?. Therefore it is Lunar. This determination was made prior to having Oxygen isotopic studies done on the material. (which as we all now know is important). ?In fact the formal presentation of this amazing little meteorite not only declares it has a Lunar origin but, it also reemphasizes the fact that these chemical ratios are actually definitive of origin. Therefore any meteorite that matches these ratios must originate from the same parent body. Which ?In that case was the Earth's moon.
> Again, I have found this is either not the case for the layman or the testing is flawed?
> Blaine knows his testing gun pretty well by now and he feels his numbers are pretty accurate and it seems to me they must be at least as good as the Mars probes and other remote sensing devises are that we use and trust?
> This said because I also have rocks that plot exactly with some of the ones the Mars probes sniffed. They too are charted and graphed so it is very easily to plot your own results right on the same charts generated by other scientists.
> I have spent Hours working on these charts and yet no matter how close they plot to other known material.
> If the rock did not fall from the sky and hit you on the head and leave fusion crust embedded in your skull. Then it is not worthy of study so these XRF tests are virtually useless???
> So, the question is ; what have ratios to do with this after all?
> It seems to me that a test that proves a rock was in space available to the public is the only real way to determine origin unless you are a Scientist working in the field. Home tests just don't seem to work out. Do they?
