"analyzed by Jose Garcia and confirmed as 11228"
Are you saying Jose Garcia has officially paired this darker stone to NWA 11228? Based on what, that is a relevant question! |

It is OK Jon. I understood you had it looked at by someone "to be sure" it was a lunar, and also that it was darker than most you've seen...you never mentioned FC. Ignore those comments is my recommendation. The meteorite police really don't exist... |

In my comment he mentioned:
* is a *fragment* analyzed by Jose Garcia in the Canarian Museum / I never said that Jose Garcia was the one who analyzed the 11228 meteorite and reported it to MBD
* with a very *dark surface*, more than normal / I never said: It is a surface with Fusion Crust |

Hello Anne Black, what I meant that this particular piece was analyzed by Jose Garcia and confirmed as 11228, I did not mean that Jose was the one who generated the report to MBD, and on the point I mentioned about its surface being darker I was not referring to Fusion Crust, I was referring to its dark hue unlike the others |

I wonder whether that rectangular protrusion is actually an anorthite crystal? |

Jonathan, according to the Met. Bulletin, it was classified by Carl Agee, of the University of New Mexico. And it is not fusion crust, it is desert varnish! Physical characteristics: Many irregular shaped fragments, dark sand-blasted exterior, no fusion crust.
Petrography: (C. Agee, UNM) This meteorite is a fragmental breccia with pyroxene, plagioclase, and olivine grains set in fine grained groundmass. Scattered micro-gabbro fragments were also observed. Ubiquitous, fine grained, accessory Fe-metal and sulfide are present. Minor amount of shock melt was observed in the microprobe section. All pyroxene grains probed were pigeonite, no augite was detected.

Thanks Ben Fisler and Bernd Pauli, It is a fragment analyzed by Jose Garcia in the Canarian Museum, and its shape is incredible, with a very dark surface, more than normal, so I bought it immediately :) |
