An uranothorianite and phlogopite deposit located NE of Andranondambo. The Hibon brothers found here a mineral that was analyzed by H. Besairie in 1947 to be thorianite. This was the first find of thorianite together with phlogopite in this area (Amboasary District (= l'Androy Mandraréen)).
"Sofia" is a misnomer that appears once in H. Besairie (1966), p. 391, but it is spelled correctly on p. 398.
