How plentiful or scarce is sulfur?

Answer 1

It is relatively plentiful around deep-sea vents, but scarce in the earth's crust. It is plentiful in the mantle, and sometimes comes up around volcanoes, creating a rotten-egg smell. This element also is found in geysers, such as in Yellowstone.

Answer 2

Sulfur is considered relatively abundant in the Earth's crust and is widely distributed in minerals and in organic matter. It is commercially produced as a byproduct of natural gas and oil refining. However, in certain regions or specific industries that depend heavily on sulfur, there may be local or temporary shortages.
