As I answered in a similar question https://astronomy.stackexchange.com/a/33651/23748, it is unlikely to be a meteorite and extremely unlikely to be a Martian meteorite.

I presume that the numbers in first line were intended to be oxygen isotopes and the formula in the last line is intended to be silicon dioxide.

What do you mean "I witnessed a meteorite fall near me"? On average there are only about 6 [meteorite falls](https://en.wikipedia.org/wiki/Meteorite_fall) per year worldwide, so it would be quite amazing if you witnessed one, and *unbelievably* good luck if you were the one to locate the crater and retrieve the meteorite itself.

Sio2 59.32 first number on my chemical analysis .when I Google this number that is no where close to retard korotev martian meteorote charts .it brings up mars .59.31 doesn't 59.33 doesn't.most all my numbers bring up mars

Where can I get a oxygen isotope analysis $^{18}O$ / $^{16}O$ vs $^{17}O$ / $^{16}O$ done commercially ? I witnessed a meteorite fall near me; it looks to be martian andesite. My first number $SiO\_2$ 59.32 and my others bring up mars first.
