Where Is Sulphur Found?

Most sulphur can be found in deep underground deposits along the Gulf Coast of the United States, as well as the volcanic areas that make up the Ring of Fire, such as Chile, Indonesia and Japan. Sulphur is the 10th most abundant element in the universe but makes up very little of the Earth's crust.

A brittle mineral, sulphur (referred to as sulfur in the U.S.) is pale yellow in appearance. Naturally occurring in iron pyrite, gypsum and other similar compounds, it can also be found in meteorites and volcanoes. One of Jupiter's moons, Io, gets it colors from different forms of sulphur. While sulphur in its natural form has no smell, when it reacts with other organic compounds, it can have a very distinctive unpleasant odor.
