The Sahatany Pegmatite Field is situated ca 25 km SW of the town of Antsirabe, and covers an area about 150 km2. This area is - in older literature - referred to as "Mt. Bity area" (for example in Am. Min. (1916) vol 1, 17-34.) More than 100 pegmatites of both beryl type LCT pegmatites and complex type LCT pegmatites are found in this area, and many of them have been worked for gem polychromatic tourmalines, rose beryl, spodumene, rose quartz etc. An inventory of the pegmatites is found in Rakotoarison, W. (1964). The pegmatites (age: Pan-African event ca 550 MA) are hosted in a Precambrian tectonic unit that consists mainly of schists, quartzites, and marbles (série schisto-quartzo-dolomitique).

Administratively the Sahatany pegmatite field is divided into to 5 different communes in two regions: (At the moment the hierarchial structure is under editing).

Vakinakaratra Region, Antsirabe II District:
- Mangarano Commune: Localities in the upper Sahatany valley.
- Ibity Commune: Most of the localities in the main Sahatany valley.
- Sahanivotry Manandona Commune: Localities south and southeast of the Ibity massif, N of the Manandona Valley.
- Marososona Commune: Localities west and southwest of the main Sahatany Valley.
Amoron'i Mania Region, Ambositra District:
- Sahatsiho-Ambohimanjaka Commune: Localities south of the Manandona Valley.
