    Viet Nam
    Vietnam Tektites are part of the Indochinite strewnfield. These tektites are among the rarer of the Indochinite tektites from the mainland of southeast Asia. Viet Nam tektites are similar to the specimens from other areas, but they have differences in texture. Viet Nam tektites may have some channeling and grooving that is not seen as much in others from the countries nearby. The patty forms from Viet Nam will often display the ray like splits along the edges seen also in tektites from other regions as well. Debate continues as to whether this flat patty form with the splits on the side is a collapsed hollow sphere or not. But many specimens show features leading some to consider this a strong possibility. The numbers of recovered specimens from Viet Nam have never been a large as from other regions making these very attractive to collectors seeking specimens from as many locations at possible.
    Tektites
    are still poorly understood. They are irregularly and at times intricately-shaped nodules and blobs of a glassy substance. They have no crystal structure, and are therefore similar to obsidian, but are not associated with volcanic processes. Their chemistry is unique and somewhat unexplained. The leading theory concerning their origin is the "Meteorite Impact Theory". It is postulated that many odd events occur during a meteor's impact because of the tremendous heat and pressure produced. Tektites may be fused glass that formed during an impact of a meteor with layers of rock on the Earth's surface. Tektites occur in broad bands in specific localities in different parts of the world. These bands produce characteristically similar tektites and are sometimes loosely associated with meteorite craters or suspected craters. Could these fields represent splash material from an impact? Many believe so and this idea is gaining acceptance from many scientists. The odd and diverse chemistry of the tektites could be a result of unique meteorites hitting unique rock types with the combinations producing particular effects. Many tektites have a teardrop shape that could easily form as blobs of liquefied quartz cooled in air while falling to the Earth.
