The Sudbury basin contains the third largest impact crater on Earth and is located in Ontario, Canada. It is best known for its unique geologic features, including shatter cones, impact breccia, and pseudotachylite. Pseudotachylite is a type of impact melt rock formed from the intense heat and pressure of a meteorite impact.

Pseudotachylite in the Sudbury Impact Crater comprises silicate minerals such as quartz, feldspar, and mica.  In addition, pseudotachylite can contain small amounts of iron, aluminum, calcium, and magnesium, which are responsible for its distinctive coloring. The main clasts are fragmented pieces of Cartier Granite and gneiss. The dark matrix is the cryptocrystalline impact pseudotachylite formed from "shock melting" due to the rapid cooling following the extreme thermal stress after a meteorite impact.

This pseudotachylite from the Sudbury Impact Crater also plays an essential role in helping to understand the region's geologic history. Detailed studies of pseudotachylite in the Sudbury Impact Crater have enabled geologists to gain insight into the timing and nature of the impact, as well as its effect on the local environment. In addition, geologists have used pseudotachylite to study the interior structure of meteorites and impact-related events.
