Sovite (orsövite) is the coarse-grained variety (orfacies) of carbonatite, an intrusive, igneous rock. The fine-grained variety of carbonatite is known as alvikite.[1] The two varieties are distinguished by minor and trace element compositions.[2] Sovite is often a medium-to-coarse-grained calcite rock with variable accessory amphibole, biotite, pyrite, pyrochlore and fluorite.[3]
