SULFUR
Sulfur makes up way less than 1% of the Earth's crust,
but it is not valuable. Elemental sulfur is frequently found at or near
volcanic vents and fumaroles. Significant economic concentrations of
sulfur are known in the Gulf of Mexico subsurface (Louisiana-Texas area).
Sulfur has a nonmetallic luster and a bright canary-yellow color (when heated
to a liquid, it becomes reddish-orange). It is fairly soft, lightweight,
brittle, lacks cleavage, and has a distinctive scent.
