Re: [meteorite-list] relationship between CV and CK
Interesting stuff Dustin. I need to read more...if I find other info or studies I let you know. Helping at the moment with materials for a parent body study but it does not include CVs or CKs at present.

[meteorite-list] AD - Small and large pieces of Famenin H/L3 hammer for sale
Hello everyone, I have a few small pieces of the Famenin H/L3 hammer for sale. They are: 2.63g, 3.3g, 4.84g, and 218g. All pieces have significant amounts of fusion crust and are lovely to look at with large chondrules. On some, you can see fragments of the roofing material that the meteorite hit. The small pieces are available immediately ($150/g) and I may be able to provide some CT scans to go along with them if there's interest. The largest piece (price is negotiable), we're still doing a bit of work on, but it could be available within a couple of weeks. For more detailed information, send me a note... Have fun!

[meteorite-list] relationship between CV and CK
Hello dear meteorite mavericks and mavens, It has been a while since I have posted to the list. I needed to test to see if my account was working before I posted an ad, but thought why waste the electrons and decided to test it with a topic I have been intrigued with lately; the relationship of the CK to the CV carbonaceous chondrites. Is anyone currently working on this? I would enjoy learning what direction you think the latest data / research is pointing. Based on a recent 2016 paper, see ref below, what I had thought was a relatively well established isotopic relationship between the CV and CK chondrites, pegging them to the same parent body, now seems to be in question. This paper raises significant issues with magnetite compositional differences in the unequilibrated CK and the CV, as well as "Oxygen fugacities and temperatures in the CV-ox - CK". This seems difficult to reconcile with some of the previous research I have read on this topic. I am hoping others might be interested in learning more about this, and discussing it a bit.
