Topaline
Topaline was a rare mineral critical to the function of life support systems for planetoid colonies in the 23rd century. Naturally-occurring, topaline also had sensor-disrupting properties.

In 2153, while evading Xindi-Reptilian seekers, Captain Archer, Lieutenant Reed, Major Hayes, and the Xindi-Arboreal Gralik Durr took refuge in a cave containing topaline ore, through which the seekers could not scan. ()

In 2267, Captain Kirk attempted to secure topaline mining rights on Capella IV, competing with Klingon interests on the planet. The mineral was present in abundance. ()
