Re: [meteorite-list] Holbrook Tektites ( Heat Testing of Tektites)
Bernd, Mark, Dennis, Brian, et al, This is quite interesting because Dennis sent me pictures of his Holbrook Tektite find and it is identical to my finds both in color ( golden brown not grey) and texture. I like that Arizonaites or Arizona Whatevers. Again they look like Columbianites and the really interesting thing is that Holbrook is quite a distance from Wilcox AZ. where I found all of mine. There are some really good pictures of Tektites in Marvin's Book. Southwest Meteorite Collection pages 182-197.

Re: [meteorite-list] Holbrook Tektites ( HEAT TESTING of TEKTITES)
Greetings to Dennis, Mark and List Members HEAT TESTING OF TEKTITE Aubrey has some good interesting observations concerning Testing Tektites on his sight http://www.tektites.co.uk/tektite-tests.html Personally , I have access to professional Glass Blowers with tons of experience.. They work with Common , Borosilicate ( Pyrex ) and Dichroic Glasses. All types of Glass have different melting temperatures , and working together with the Top Production planner ( Brent ) who is versed in Heats and Flames required for melting these various types of glass, we set about to Heat Test Several Types of Tektite. Temperature is KEY to observations. Brent was aware of our goals and took time to test various temperatures as well as using test pieces and had far more information than I am able to convey simply. Lets just say that Coefficient of Expansion, Coloration and other physical properties were also in question during our tests. Glass melts at a relatively LOW Temperature, about 485 Centigrade / 900 Degrees Fahrenheit ( Varies with the amount and types of Alloys in the glass ) Bolorsilicate ( Pyrex ) at about 820 Centigrade / 1,510 Degrees Fahrenheit Thailandites, Philippinite , Moldavite and Quartz Glass melt at about 1,665 Centigrade / 3,029 Degrees Fahrenheit Libyan Desert Glass - we took it up to 1,815 Centigrade / 3,300 Degrees Fahrenheit and it was tacky on the surface , BUT did not Melt, as my friend stated it is laughing at us... We are still looking for a hotter Hydrogen Flame Unit to see what the actual melting point is. Darwin Glass - I have yet to test it, I forgot to bring samples. Maybe soon... Obsidian explodes when heated quickly. SO - it is easy to eliminate an Obsidian as a Tektite , just by throwing alot of heat at it quickly. Glass and Borosilicate varies from Tektites , easily, by applying heat to samples of each set side by side, see what melts first .. Don't worry about destroying the Tektite , it will be safe since the glass will melt much sooner than any tektite, and if the Tektite melts at the same temperature as Glass ?? It was not a Tektite. Quartz Glass is rare and to find a piece while looking for Tektites is just to unlikely to ever happen. The reason Tektites can withstand such High Heat is that the impurities that allow Glass to melt at lower temperatures have been Burnt out of them already. MY THEORY: Thailandites, Philippinite and Darwin Glass have coloration from the residue left by these Burnt off elements. Heavily contaminated. Moldavite also gets its coloration from the Burnt off elements. Less Contamination Libyan Desert Glass is very clean and was intensely heated to remove even the residual left by burning off impurities. Minimal Contamination. Highest Regards to All Brian S.

Re: [meteorite-list] Holbrook Tektites ( HEAT TESTING of TEKTITES)
Very well done Brian! Thanks for sharing your results. Your experience with the LDG, Libyan Desert Glass - we took it up to 1,815 Centigrade / 3,300 Degrees Fahrenheit and it was tacky on the surface , BUT did not Melt This made me wonder again what others think of the idea that LDG is a glass meteorite and not a glass created in the same manor as most tektites. This is not original thinking on my part as I have heard it proposed as one of the theories on LDG. Any thought on this? Some samples of LDG are shaped more like a meteorite than a tektite aside from the fact that they are glass! Tom In a message dated 8/27/2010 3:24:13 A.M.

I found some beauties east of *Safford*, Arizona back in the 1960s. Three are illustrated in the May 1967 issue of Sky Telescope. Some start out as Apache tears (Safford site) others break out of obsidian flows. Often they become worn down to oval shapes that look like splashform tektites. But all I have ever seen are banded, whereas splashform tektites all have a contorted flow structure. Sometimes they even have tektite-like colors, but they are never of tektite quality they will eventually devitrify.

Re: [meteorite-list] Holbrook Tektites ( HEAT TESTING of TEKTITES)
Brian, Tom, List, Libyan Desert glass is 98% pure silica, the purest naturally discovered glass on Earth. http://www.pisces-press.com/C-Nav/ldg.htm While one sees as examples are clear, gem-like LDG, many of the fragments found on the ground (and tossed aside as dirty or not pretty enough) are tabular and layered, clean, dirty, clean, dirty, like the Muong-Nong tektites found in Laos and Thailand. Boslough at Sandia has a airburst theory... naturally: http://www.sandia.gov/news/publications/technology/2006/0804/glass.html Most people think an impact origin. Too many references to cite. There are some completely dopey theories about LDG, too. I found this one to be worth a good laugh: http://www.b14643.de/Sahara/LDG/index.htm And there are some people still think tektites are volcanic: http://www.rasc.ca/journal/pdfs/2004-10.pdf Analysis of LDG can be found in Christian Koeberl, A Meteorite Component in LDG. He finds excess cobalt, nickel, iridium: http://www.lpi.usra.edu/meetings/metsoc2000/pdf/5253.pdf Here's the actual earlier work by Koeberl, the full paper, with complete data: http://www.univie.ac.at/geochemistry/koeberl/publikation_list/132-Libyan-Desert-Glass-Proc-Bologna-Mtg-1997.pdf Anyone have an idea why there's a ten-fold excess of uranium in LDG? I'm sure that's spawned a few whacko websites! I quote from Koeberl ...none of the sands or sandstones ...are good candidates to be the sole precursors of LDG. Formation temperature has to be high enough to melt zircons, as they contain melted zircons (as many tektites do). Ever tried to melt a natural zircon? What is often missing from the discussions of the origins of the LDG is the fact that the Libyian-Egyptian Desert pf 28.5 million years ago was NOT a desert. It was swamps, vast lakes, bogs, and snaking bayous. What was not open water was wet and very densely forested between 24 and 32 million years ago. The Sahara to the west and south was grasslands and scattered forest. Yeah, I know. Doesn't look it, does it? But in the Oligocene Epoch it was more like the Amazon Basin on a smaller, dryer scale. It's a rich source (only source, actually) of fossils of early primate ancestors of apes and men. It seems to be where we learned to hang out in trees (literally), the black anaerobic crap underneath being something you didn't want to fall into. These wet basins were filled with hundreds of feet of sand blown in from the west as the Sahara began to dry out. This is the target geography that an impactor would have struck. The high silica content pretty much has to mean that LDG was made entirely from sand. The fact that LDG is not as dry as most tektites may come from the fact that the target soils were underwater some depth. Merely geusses, though. Is there a good book on tektites? No. The study of tektites drives people crazy, and crazy people do not write good books... O'Keefe's 1976 Tektites and Their Origins book was posted online for years but it's gone now. You can get a copy on Amazon for $200. (O'Keefe was the O of the YORP Effect or Yarkovsky-O'Keefe-Radzievskii-Paddock Effect). Other books by Heinan and Provenmire are hard to find.
