[meteorite-list] Meteorics Master Degree Ideas and Educational Institutions
Hello List, I've been entertaining the idea of getting a Masters Degree in the realm of meteorics for a few months now, and felt it high time that I do some research on the matter. I have a BS in geology and having never been taught an iota about meteorites in 4 years (can you believe that!) Im a bit at odds of where to start searching. I know of a few schools with related programs, simply because of classifying and lab work etc, but am unsure if they are simply labs or have programs for degrees. I figured I'd start here, as a quick reply here by more knowledgeable folks can most likely save me many hours of research. What schools have space/meteorics programs? Also, does anyone have some ideas for a Masters Degree project? Im a very field oriented geologist, however fieldwork seems to be somewhat limited in meteorics (besides ANSMET), but i'd love to hear what possibilities could await me! Thanks, have a great rest of the week. cheers, ryan weidert. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
[meteorite-list] AD - New Collector Rock TRADE
Hi All, I sent this out last week and had a few replys (Thanks!) and thought I'd try it one more time. I've been reading the list for a few months now and finally thought I may have something to offer (albeit somewhat self-centered). Im a new collector of meteorites, and am looking to trade mineral specimens for meteorites or related things to bolster my tiny collection. Im a geologist, and have been an avid rockhound for the last 10 years of my 25. That said, I have a literal ton of rocks and I figured that since this list deals with meteorites, I should try and offer things that are more related to space rocks than not. Im simply looking to swap some of my extra rocks for some of your extra space rocks. I know meteorites are or can be expensive, so im willing to trade what you think is fair. If you are looking for some specific mineral/rock, ask and I may have a sample or two somewhere. Email me at ryan.weidert at gmail.com if interested or have any questions. I'd be glad to answer them (if I can haha)! Thanks! Have a Great Weekend! ~ Ryan Weidert I have the following Earth rocks up for trade: All Photos- http://s261.photobucket.com/albums/ii66/no-limitation/Rock%20Trade%20for%20Meteorites/ ) Olivine Nodules (volcanic bombs) - the same mineral in those beautiful pallasites except from the Earths mantle, 30+ miles down! - whole with basalt crust - broken exposing crystals - numerous large fragments - cut pieces upon request Olivine Sand (crushed and screened nodules) - <1mm unsorted - 1-2mm unsorted - 2-4mm unsorted - 3-5mm hand picked "apple green" crystals. - 2-3mm hand sorted "apple green" crystals. Moqui Marbles - Spherical (or nearly so) hematite concretions formed within sandstone. - "Classic" newbie meteorwrongs Obsidian Nodules - "Classic" newbie meteorwrongs - Some have nice "regmaglypys" Other rocks... Cleavelandite (Albite - a fledspar) - Large specimens (most over 10cm x 10cm - Many with mica Quartz Crystals - A few larger ones (~5x10cm) - Opaque to near crystal clear Geodes - Hauser Beds, Southern California - Uncut 'nodules' up too 8cm across. - note, some may not be hollow inside. __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Making meteorite thin sections.
Hi Ed, Thin sections are a bunch of work and have to be withing pretty strict parameters to let light through correctly. Although I've never made one myself before, I have friends whom have had to make hundreds for their masters/PhD projects and its pain, unless you like grinding, glueing, grinding. When done correctly, and with polarized light, the results (depending on the minerals) can be absolutely astounding natural work of art. Here's a link I came across on how to make one. http://almandine.geol.wwu.edu/~dave/other/thinsections/ good luck! If you don't feel you're up to the task of making them, you can send rock/meteorite samples to be made for you, but of course its money, and the wait can be pretty long (months) to get them back. -ryan __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
Re: [meteorite-list] Contamination during cutting - what impact does it have on analysis?
Hi Mike, I just was reading last night about how they cut the Antarctic meteorites and they did a study on what is imparted to the meteorite from the blade (they don't use any coolants while cutting). Diamonds and some of the metal does smear and stick to the meteorite. Here's the link to the article (half way down the page). http://www-curator.jsc.nasa.gov/antmet/bandsaws.cfm The study also found traces of "organic" compounds that were contamination due to the plastic bags they used. Everything at some level is a contaminant, but I'd think certain obvious things are noticed and disregarded. NASA uses a nitrogen cabinet to store and cut their meteorites to prevent oxidation. Yes, they are more concerned about contamination due to the 'pristine' nature of their meteorites (no or little contamination from air pollution etc), but it still happens. I agree that water must do something to the chemistry, but not a clue what. -cheers, ryan __ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list Meteorite-list@meteoritecentral.com http://six.pairlist.net/mailman/listinfo/meteorite-list
