Mineral specimens found in one of the numerous localities in the area north of Amboasary, especially in the Communes of Tranomaro and Maromby, lacking specific locality data have often erroneously or incompletely been labeled just "Tranomaro" or "Tranomaro area" since Tranomaro is a center in this area.
Please see the entry for either Tranomaro Commune or the Maromby commune for the different localities.
A new find of grandidierite from an undisclosed locality in the Tranomaro area was made in 2015 (Vertriest et al. 2015), for further information see Unnamed grandidierite deposit.

Geochronology
Mineralization age: Mesoproterozoic to Ordovician : 1330 ± 40 Ma to 480 ± 20 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.
