Androy refers today to the area and the administrative region west of the river Mandrare and east of the Manambovo river.
The name "l'Androy Mandraréen" is used on old maps and in elder, mostly French mineralogical literature as a designation on the area east of the Mandrare river; this area belongs today to the Amboasary District in Anosy region and must not be confused with the "Androy Region".

Geochronology
Mineralization age: Neoproterozoic to Cambrian : 613 ± 45 Ma to 515 MaImportant 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.
