[meteorite-list] TEKTITES VS. TEARS
Hello All, Here's a new California locality - Antelope Valley On the flanks of the foothills, just south of the aqueduct and within sight of the Neenach (L6) site. Here are some URLs: http://meteorite-recovery.tripod.com/av-ranch/obsidian.htm http://meteorite-recovery.tripod.com/av-ranch/obsdian2.jpg A couple of years ago, a rancher contracted our Meteorite-Recovery Team to search his property. Although no meteorites were recovered, we did find some 80 year old iron artifacts, some stone (paleo-Indian) artifacts, and a new locality for apache tears obsidian. [Not likely these would be confused as being tektites.] Team member Randy Duncan went on to find a new locality (in Owens Valley) for an apache tears variety of obsidian that looked just like tektites. Sorry, but I don't have any images of those stones. Bob V. [meteorite-list] TEKTITES VS.

Re: [meteorite-list] TEKTITES VS. TEARS
I don't have that many tektites.. a couple of pounds I guessBut they do not look anything like apache tears, snowflake obsidian or regular obsidian to me. Wabar pearls may be similar to obsidian in appearance.. but not apache tears...So I am ignorant of the problem. Apache tears come form the Superior mine in Arizona. I do not know where else.

Hi, Obsidians have hundreds to thousands of times more water in them than tektites. Heat obsidian in a vacuum and watch it bubble away like crazy. Tektites basically just sit there when heated; there's nothing to outgas. On the other hand, the furnaces are hard to carry to shows, there's no 440 V. lines available, etc., etc. But it's a positive test. Sterling K.
