Exempel på hur man kan använda TEKTITES i en mening

• Evidence for the crater's impact origin includes shocked quartz, a gravity anomaly, and tektites in surrounding areas.
• Second, although high in silica (>65 wt%), the bulk chemical and isotopic composition of tektites is closer to those of shales and similar sedimentary rocks and quite different from the bulk chemical and isotopic composition of terrestrial volcanic glasses.
• The layer contained the fused glass beads called tektites and shocked quartz grains that are unmistakable signs of a bolide impact.
• Lechatelierite also forms as the result of high pressure shock metamorphism during meteorite impact cratering and is a common component of a type of glassy ejecta called tektites.
• The Tanis site in North Dakota contains possible evidence of the Chicxulub meteorite impact—such as the chaotic mixing of fossil carcasses and a layer of glass tektites with associated impact impressions—deposited minutes to hours after the impact.
• The main evidence for the Alvarez hypothesis that the Chicxulub impact resulted in the Cretaceous–Paleogene extinction event, supported by earth sciences consensus, comes from the presence around the world of shocked quartz granules, glass spherules and tektites embedded in a layer of clay with extremely high levels of iridium, all signs of an asteroid impact.
• The largest indochinite is a Muong-Nong type tektite (which are layered tektites), which had a mass of 29.
• Splash-form tektites are tektites that are shaped like spheres, ellipsoids, teardrops, dumbbells, and other forms.
• Chao, who is known for coesite, stishovite, and tektites, as they were both at one time in the USGS Branch of Military Geology, though they had no scientific relationship.
• millions of "near perfect" primary (not reworked) microtektites "almost indistinguishable" in chemical composition from previously reported Chicxulub tektites, buried contemporaneous to the fossils, in their own impact holes in the soft riverbed mud, and also preserved in amber on tree trunks.
• The North American tektite strewn field is a large area, known as a strewn field, in North America defined by the presence of tektites consistent with having come from the same bolide.
• Tasmanite are tektites found in Tasmania, a regional form of australite, the most common type of tektite, glass of meteorite origin, traditionally named for its geographic location.
