North of Seguela around Bobi and Toubabouko a number of sheared dikes cut Precambrian granitic rocks and were described by Bardet (1974) as "meta-kimberlites".

Diamonds are recovered from alluvial deposits associated with both Bobi and Toubabouko dikes. Production statistics for the 1950s and 1960s are given by Bardet (1974).
The dyke of Bobi (BD) is 2.5 km long and 25 to 50 cm wide.

Geochronology

Mineralization age: Mesoproterozoic : 1429 Ma to 1145 ± 6 Ma

Important 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.
