The above is a quoted from the lyrics of Jeff Wayne's War of the Worlds however it should be noted that the original quote from HG Wells is :
"The chances against anything manlike on Mars are a million to one," he said.
Well today i finally got hold of a piece of mars..yesy a REAL PIECE OF MARS !!
But if no one has ever been to mars and no samples have been collected and bought back then how can I have a piece of Mars ? Well as you know Mars has been hit by many impactors and many of these have been on a biblical scale, see my thread " Be Afraid..Be very Afraid" http://www.black-and...be-very-afraid/
Now when some of the large impacts occurred martian rock was blasted out into space and some, after many millions of years, have landed on earth as martian meteorites ( Shergottites) I think to date there are under a hundred know Martian meteorites http://www.lpi.usra....rec=50&srt=name
Mine is a 1 cm slice from meteorite Dar al Gani 1037 which was found in 1999 in Libya, The numerous impact shock veins, Melt veins + melt pockets suggest that this specific rock material was from the exact zone on Mars that was hit by the asteroid that caused the material to leave Mars!
Ten stones totalling 4012.43 g were found early 1999 in the sand desert of Dar al Gani. The biggest individual was a complete individual of 3090 g with perfect orientation and rather fresh appearance. Classification and mineralogy (A. Greshake and M. Kurz): an olivine-phyric shergottite with porphyritic texture; large chemically zoned olivine megacrysts are set into a fine-grained groundmass composed of pyroxene and maskelynite; minor phases include chromite, Ti-rich chromite, sulfides, phosphates, and small Fe-rich olivines; olivine megacrysts often contain melt inclusions and small chromites; pyroxenes are dominantly chemically zoned pigeonites, some contain orthopyroxene cores; olivine phenocrysts, Fa31.4-41.1, Fe/Mn = 52-59; matrix olivine, Fa37.4-40.6, Fe/Mn = 52-58; pigeonite, Fs23.7-35.4Wo6-18.6; orthopyroxene, Fs20.2-24.5Wo2.5-4.7, Fe/Mn = 34; maskelynite, An58.9-65.5; heavily shocked with numerous melt veins and melt pockets; moderately weathered with calcites filling cracks and cavities. Oxygen isotopes (R. Clayton and T. Mayeda, UChi): δ17O = +2.91, δ18O = +5.29, Δ17O = +0.16. Possibly paired with Dar al Gani 467, 489, 670, 735, 876, and 975. Specimens: main mass with anonymous finder; type specimen 20 g plus one polished thin section MNB
And now the image, sorry my first experiment with Macro photography, i have a lot to learn
