Which type of meteorite is derived from the fusion of silica and other materials?

Tektites are a specific type of meteorite formed from the intense heat and pressure generated during the impact of a meteorite hitting the Earth. This high-energy event causes the melting and subsequent fusion of silica and other materials at the impact site. As these molten materials are ejected during the impact and then cool rapidly, they solidify into glassy, typically small fragments known as tektites.

The process behind tektite formation is unique among meteorites, as it involves both terrestrial materials and the energy of a celestial impact. In contrast, chondrites and stony meteorites are composed primarily of minerals and are not the result of such impact-induced melting, while siderites are primarily iron meteorites formed in asteroids and do not include the fusion of silica. Thus, the distinctive nature of tektites makes this option the correct choice in relation to the fusion of silica and other materials.
