Type:
Early Paleogene (63.65 ± 0.52 Ma, 63.11 ± 0.45 Ma) syenitic complex of the Seychelles microcontinent. The complex is composed principally of diorite, syenite and microsyenite (Shellnutt et al., 2024). The rocks are compositionally similar to the A1-type granitoids.
"The emplacement of the North Island complex is contemporaneous with the eruption of the Deccan Traps and rifting of the Seychelles microcontinent from India. Rifting and magmatism was likely related to the passage of the Indian plate over the Réunion hotspot." (Shellnutt et al., 2024).
