Mt. Bity area


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 5 different communes in two regions: (At the moment the hierarchical 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.

Formula: A(D3)G6(Si6O18)(BO3)3X3Z
Localities: Reported from at least 46 localities in this region.
Colour: red, pale rose, green; reddish-purple; dark-olive brown
Description: Nizamoff et al (2000) describes 3 types of tourmalines found at Antandrokomby : Type I: prismatic zonated crystals up to 30 cm with dark-olive-brown core and thin dark-red rim. These were found mostly in the massive pegmatite (and which rarely protruded into the pockets). Type II: stubby, zoned, reddish-purple up to 4 cm with dark-olive brown cores and dark red rims (found in miarolitic pockets) Type III: Vibrant pink unzoned crystals less than 2 mm which forms masses of fibrous crystals. Nizamoff et al. (2000) further states that the types I and II from Antandrokomby have dark brown cores that are schorlitic in composition. Weber et al (2002) further states: " Electron microprobe analyses reveal that the tourmalines are not liddicoatite, but principally schorl to elbaite in composition". Ranorosoa (1986) analyzes pink, green and brownish tourmaline found at the pegmatite contactzone (equal to Nizamoff et al.'s type I) and find it to be elbaite in composition (Look under elbaite for further info)

Geochronology

Mineralization age: Neoproterozoic to Ordovician : 652 ± 45 Ma to 464 ± 9 Ma

Important note: This table is based only on rock and mineral ages recorded on mindat.org for this locality and is not necessarily a complete representation of the geochronology, but does give an indication of possible mineralization events relevant to this locality. As more age information is added this table may expand in the future. A break in the table simply indicates a lack of data entered here, not necessarily a break in the geologic sequence. Grey background entries are from different, related, localities.
