Tektites, which are natural glass objects formed by the impact of large meteorites on Earth's surface, typically do not contain other minerals, inclusions, or fossils. Their formation process involves the melting and rapid cooling of terrestrial material, which generally results in a homogenous glassy texture devoid of crystalline structures or organic matter. According to research published in the Journal of Geophysical Research and studies by the Geological Society of America, tektites are primarily composed of silica, with minor amounts of aluminum, iron, and other elements. The rapid cooling process prevents the crystallization of minerals and the preservation of any pre-existing inclusions or fossils.
However, some rare exceptions exist where tektites may contain microscopic inclusions. These are typically tiny bubbles or vesicles formed during the rapid cooling process, as noted in studies by the American Mineralogist. Occasionally, tektites may also exhibit lechatelierite, a high-temperature form of silica, as a result of the extreme conditions during their formation. These features are not considered true mineral inclusions but rather byproducts of the tektite's formation.
In summary, while tektites are generally free of other minerals, inclusions, or fossils due to their unique formation process, they may occasionally contain microscopic features like vesicles or lechatelierite.
