Sovite (sövite) is the coarse-grained variety or facies of a carbonatite intrusive. The finer-grained variety is known as alvikite. The two varieties are distinguished by minor and trace element compositions. Sovite is often a medium-to-coarse-grained calcite rock with variable accessory amphibole, biotite, pyrite, pyrochlore and fluorite.
