The Amboasary District, especially the area north of the town Amboasary and on the eastern side of the river Mandrare; - from Behara to Esira- is famous for its many thorianite and phlogopite deposits.
This area has been, in earlier maps and writings, named (in french ): L'Androy Mandraréen. The name Androy (stricto sensu) is today the name of the area and the administrative region west of the river Mandrare.
Thus the name "L'Androy Mandraréen" refers not to the Androy region but to the northern area in the Amboasary district.
Labels:
Old (and newer) labels with minerals from the Anosy region can have a reference to Androy (ex. locality, Androy, Fort Dauphin)- thus meaning "L'Androy Mandraréen" and not the Androy Region.
