Svabite is a rare accessory mineral in calc-silicate skarn.

At Harstig mine, Sweden, svabite occurs with manganoan diopside, manganoan aegirine, garnet, brandtite and sarkinite.

At Långban, Sweden, svabite occurs with with manganoan diopside, tilasite, manganberzeliite, bergslagite, hematite, calcite, baryte, mica and garnet.

At Jakobsberg, Sweden, svabite occurs with hausmannite.

In the Ural Mountains of Russia svabite occurs with vesuvianite in pyroxene-garnet assemblages and in zones with spodumene, which alters to szaibelyite and brucite.

At Franklin, New Jersey, USA, svabite occurs embedded in franklinite ore.
