Date: Wed, 7 Jul 2010 13:54:55 +1000 (EST) Message-ID: <51771.121.222.185.103.1278474895.squirrel_at_webspace.ezadsl.net.au> Michael and other lesser listoids Due to popular demand I have restored the MOSSGIEL meteorite thin-section webpage http://www.qmig.net/mossgiel HUCKITTA has been retired... I have to admit that MOSSGIEL had been my favourite so far so back it goes ! Thin-section index webpage http://www.qmig.net/thinsection updated too ! And a gentle reminder to Michael you gave the listoids the wrong hyperlink to the index page - and yep your faves COLE CREEK and NWA 1955 are there too I second all the posts that call for an article on a inexpensive but elegant solution for readers to view and photograph their thin-sections in xpol light - any takers for the definitive article to bowl this one out once and for all ? I'll be out of action for a week or so because I'll be admitted to hospital tomorrow but youse can expect an update to my thin-section webpages next week with a few surprises ! I'd gently remind listoids that I have asked youse if I can SHORT-TERM borrow any interesting or pretty thin-sections to micrograph - very little help so far... the endstate I seek is a few pages on each type/classification with a must-have book to be written by a colleague Signing off for now Bob WALKER http://www.qmig.net/thinsection > Hi Bob & all, > Unfortunately, Jim Tobin quit making the MBC-10 > And the universal adaptors for Xpolarized lighting.
