Hi Phil and List Members, A lot of questions are being asked about the new mesosiderite. A very good question was asked by Phil and posted to the list which I will address.
> Where and how do they draw a line between unbrecciated mesosiderites and > silicated irons? Sometimes the all important O-isotopes show the proper parent body which is the case for the NWA 1878 mesosiderite. The Isotopes and chemistry are completely different from that of silicated irons. I hope this answers this question because I am certainly no expert in this area. Another question was: > Hi, has a subclass for this meteorite been determined yet? No, but I bet it falls into a very rare one because it is so different from others we have studied. I hate to hazard a guess at this time because I am not an expert on mesosiderite subclasses. They are probably only a couple of scientists who make this distinction which will be consulted. Thank you for the interest in this new meteorite.
