MeteoritesA Martian Nakhlite

12th Aug 2014 10:31 BSTAugust Rehg

the specimen attached here is about 12 x 5 x 5 cm in dimension and has distinctive "blueberry" spherules. these spherules are also purple, black, and tan colored. the rock seems to match Nakhla, NWA 998, NWA 5790, Governador Valadares and other "Nakhlites". i have yet to find any high-quality images (most are blurry) of Nakhla or of other rocks claimed to be nakhlites. please give me feedback. thank you

a couple more images...

No, this is not a nakhlite, and the match to one is very poor. This is a very terestial rock, probably a slightly altered granite.

Rotten iron stained granite is all August.

12th Aug 2014 14:33 BSTReiner Mielke Expert

Yes sure looks like a granite to me as well.

thanks for your feedback folks, much appreciated. but what do you make of the purple, blue, and beige colored spherules that are visible all around on the rock? and also please Google search for images of nakhla, and associated "nakhlites". anyone know of any high quality images online? i have yet to find any. thank you.

14th Aug 2014 03:07 BSTAugust Rehg

interesting similarities/observations of mine (all folks please view with an open mind, is all i ask of you): please do Google image search for invertebrates cnidarian and or poriferae zygotes and planulae, and cnidarian pedal disks and cnidaria oral disks and martian newberries/blueberries i shall post more photos in followup message.

See if you can gently scrape off the dark spherules, to check if they are in or on the rock - it is possible that a spider may have once resided on it... Did you try cleaning your specimen? I use soft toothbrush and soapy water as initial treatment on my finds.

Where was the specimen in the original post found? Could be helpful to us. And, if you are trying to identify a nakhlite (martian meteorite), why are you referring us to pictures of fossils? (And, this isn't fossildat) No fossils on Mars, so far as we know, and they certainly wouldn't match the old critters here on Earth. Further, the "blueberries" have been found in places here on Earth, I don't recall where, though. The original rock looks to be quite weathered; your "blueberries" could be weathered pyrite or garnet, depending on what the original rock was. And, I try to keep an open mind; the problem with that is that many things fall out and I can't retrieve them......

Hi August.


Your specimen does not appear to be a meteorite to us.


That is the best advice we can give you. If you want further assistance then you should send the sample for analysis to one of the labs that specialise in meteorite identifications.


Unfortunately there isn't any more we can do to help, therefore I am closing this thread.
