Serpentine is a class of rock forming minerals resulting from hydrothermal metamorphosis of ultra-mafic rock. In Geologica, these formations consist of serpentinite (an aggregate of serpentine minerals), intermixed with specific ore and mineral blocks at specific frequencies, representing the mineral heterogeneity found in economic deposits. Serpentine deposits occur in all domains, and are twice as frequent in volcanic regions and the ocean. Below, we list each type of ore/mineral, along with its frequency. The remaining composition is general serpentinite, as well as some peridotite that has been spared from metamorphosis.

Ore/Mineral Frequency
Soapstone (talc) 10%
Magnesite 1%
Chrysotile 0.9%
Pentlandite 0.5%
