Monoliths
From Alpha Centauri Wiki
Monoliths are mysterious and unexplained alien devices which possess amazing psycho-technical powers.
A monolith will increase a combat unit’s morale or life cycle one level, but an individual unit can receive only one monolith upgrade. A monolith, when used to upgrade has a 1/32 chance of disappearing permanently
A monolith can completely repair any damaged land unit; this can be done any number of times, even if a unit has received a morale upgrade from a monolith.
Monolith squares produce 2 Nutrients, 2 Minerals, and 2 Energy each turn regardless of the underlying terrain.
A Base cannot be founded on a monolith square and only roads, mag tubes, fungus, and rivers may be added to a monolith square
