[meteorite-list] Mesosiderite Redux
I want to thank all who offered input on my mystery specimen and whether or not it could be a mesosiderite. Some said the pic was too blurry to really see, so I took a good clear closeup. Here it is; http://www.meteorite-dealers.com/images/mesosiderite2.jpg Exterior shot isn't as clear but shows the general texture of the specimen; http://www.meteorite-dealers.com/images/mesosiderite4.jpg Don't mean to hammer this question to death but I am still interested in input with these clearer shots. For example, are the greyish blobs chondrules or not?

Re: [meteorite-list] Mesosiderite Redux
Hi, My thoughts are that, that is NWA 074, (an H6 chondrite) I have seen a largish slice of that before and it is nearly identical! Very large amounts of uniform metallic iron just like that, and not many if any distinct chondrules (at least visually).

Thanks for the specific reference Mark. I've looked at some pics of nwa 074 and concur with you. They do look like the same material.

Re: [meteorite-list] Mesosiderite Redux
Yep, it is certainly as close as it gets, from a photo at least, I was pretty amazed by NWA 074 first time I saw it, actually, its quite stunning for 'just an H6'. I think the key giveaway is in the uniformity of the Iron, in a MESO I would have expected a bit more 'clumpyness' to the Iron, the slice you showed has a nice uniform interspersion of metal just like in an H. There also appears to be slight chrondule like features in the matrix, and from what I remember of NWA 074 the matrix is a generally a light brown colour (due to the higher iron), which actually hides the light brown chondrules that are there quite well! Just my thoughts mind you, worth getting it checked out if you are unsure. Best Mark Ford -Original Message- From: Gary K.
