Crystallization occurred in fault planes and lenticular bodies in the ore bed or by filling veins and vugs.

[7] Manganvesuvianite has been found in association with calcite, manganese-poor grossular, hydrogrossular-henritermierite, mozartite, serandite-pectolite, strontiopiemontite-tweddillite, and xonotlite.

[3] In 1883, Arnold von Lasaulx made the first detailed description of vesuvianite containing up to 3.2 wt% MnO from Lower Silesia in Poland.

[4] In 2000, vesuvianite was found containing up to 14.3 wt% MnO from the Kalahari manganese fields of Northern Cape Province, South Africa.

[10] Manganvesuvianite proper was discovered in the Wessels (27°6′56.43″S 22°51′27.87″E / 27.1156750°S 22.8577417°E / -27.1156750; 22.8577417) and N'Chwaning (shaft II; 27°8′6.84″S 22°51′55.99″E / 27.1352333°S 22.8655528°E / -27.1352333; 22.8655528) mines of the Kalahari manganese fields[3] and described in 2002 in the journal Mineralogical Magazine.
