Hello Steve and List, "What is a muong nong tektite ... What do they look like and what is the composition?"
Muong Nong-type tektite characteristics: - they are relatively large and blocky - they are layered - they do not display an aerodynamic shape - they are more internally heterogeneous in texture and chemistry - they have more bubbles than "normal" indochinites - they have higher volatile element contents - some contain relict minerals - they are related to the normal (splashform) Australasian tektites => similar age => similar chemical and isotopic composition - they represent a more primitive, less altered stage - they mostly come from an approximately 800 by 1100 km area encompassing parts of Cambodia, Laos, Thailand, Vietnam, and southern China Reference: Meteoritical Society, 1992 C.C. Schnetzler (1992) Mechanism of Muong Nong-type tektite formation and speculation on the source of Australasian tektites. ______________________________________________ Visit the Archives at http://www.meteoritecentral.com/mailing-list-archives.html Meteorite-list mailing list [email protected] http://six.pairlist.net/mailman/listinfo/meteorite-list
