Deep Subterranean

This layer shows deep underground resources which can only be exploited with specialized mining/drilling technologies. The most common resource found here is oil, but caches of diamonds and other materials are also strewn below the surface of the planets just waiting to be discovered.

Investigating the deep subterranean layer can also yield information about planets and resources in general, and such information can strengthen other research.

Specialized heat energy technologies can utilize heat from the depths to generate power more efficitently than surface ground heat.
