I will address this to the list in hopes of saving some time later. Here are some questions and answers: Q. What is the status of the Park Forest splash-forms? A. Inconclusive, the O-isotopes place this material with CI chondrites not the L5 range as would be expected if this was part of the Park Forest fall. We have no answer for this very strange result. Scientists refer to this material as "Damn Crazy Glass" so we will leave it at that. Q. What are the subclasses of the mesosiderites you are working with? A. Provisionally NWA 1878 is a 2B, provisionally NWA 1879 is a 2C and our unserialized mesosiderite has not received enough study to make a determination. Two separate laboratories are trying to sort this out. Q. Just how many "Olivine Diogenites" are there now and are you sure that your find, NWA 1459 is not paired with your new acquisition, NWA 1877? A. Fair question, there are only five, three of which are from Antartica. NWA 1459 and NWA 1877 have numerous differences which will be addressed in an abstract proving they are not paired. A definition is being written for this new main class which will differentiate between Olivine-bearing (<10% olivine), Olivine-rich(10-20% olivine) and an Olivine Digenite (over 20% olivine). This data is provisional and is subject to change in the future. As it stands now, there only five "Olivine Diogenites." Q. Where did our non-NWA lunar come from and why is it taking so long to get formal paperwork? A. The non-NWA lunar came from Egypt, a very thorough study is being performed in order to produce a major document, a Ph.D. paper. Do not worry, the specimens we provided have been double checked at the UofW and are definitely lunar. Q. Why are you guys so secretive about the material you are working on? A. We try not to be too secretive but want to respect works-in-progress by scientist who in some cases want to present an abstract for publication. It is hard not to jump the gun sometimes when dealing with classifications. We try to be 99% sure of what we are dealing with before offering to the public. If we are not 100% sure we will note this when referencing the material, most of the time using the word provisional. Q. What are you working on now that is special? A. We are working on a couple of hard to describe, one-of-a-kind meteorites with no way to fit into the current classification system as they have never been found before. One of these is so interesting that it was questioned if it was even a meteorite which has since been proven. We literally study hundreds of suspected meteorites a year in hopes of finding new interesting material and it seems to be working, at least for now. Thank you for your patience regarding this long post. It is our hope that it answers some frequently asked questions. If you ever have a question feel free to ask and we will do our best to answer.
