The Anjanabonoina pegmatites are famous for their large and multicolored tourmalines. Located 42 km WSW of the town of Betafo in the central highland of Madagascar.
These pegmatite dikes outcrop at a hill (with an elevation of about 1,400 meters) 2.5 km east of Mount Ikaka and are emplaced in a complex environment characterized by paragneiss, marble, and orthogneiss of the Neoproterozoic Itremo Group, of medium metamorphic grade. The subhorizontal bodies of pegmatite are strongly zoned. The metasedimentary rocks hosting the pegmatitic dikes locally show extensive contact-metasomatic phenomena. Abundant tourmalinization extensively affected schist and quartzite units, with schorl-dravite replacing up to 30% of the rock volume. Veins of quartz, dravite-schorl, and danburite are locally present in metasedimentary rocks close to the pegmatites, and marble is transformed into skarn (De Vito et al. 2006).
The Anjanabonoina pegmatite shows the characteristics of both lithium–cesium–tantalum (LCT) and niobium–yttrium–fluorine (NYF) pegmatite families according to pegmatite classification by Simmons; these hybrid pegmatites are very rich in rare elements which contributes to the crystals’ formation in mialoritic cavities known as pockets. Gem-bearing pockets usually represent the ultimate concentrations of exotic elements, volatiles and other fluxes present in pegmatites.
- Locality misspelled as "Anjanabonsana" in Lacroix (1909).
- A gem-quality purplish-red tourmaline sample of alleged liddicoatitic composition turned out to be Ca-rich elbaite in composition (Bosi et al.. 2021).
