Nigrub El Fokani


Emplaced in Precambrian granite gneisses, amphibolites and schists, the complex comprises a central nepheline syenite stock, an inner ring of essexite, and a partial outer ring of peralkaline granite. The northeastren part of the intrusion is hidden beneath volcanic rocks representing the remains of a volcanic cone.

Geochronology

Mineralization age: Phanerozoic : 142 Β± 3 Ma to 34.1 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.
