Coc Pia
The complex has 3 distinct areas of lamproitic rocks associated with it - namely, Coc Pia, Sin Cao and Nam Hon - which are generally referred to as Coc Pia (Polyakov et al. 1997).
Tran el al. (2016) also refer to lamproite occurrence at Pin Ho and Si Mang Khang c. 30 km N of Coc Pia and Sin Cao.

Geochronology
Mineralization age: Eocene : 42.3 ± 7.2 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.
