THE FIRST FINDING OF MINERALS OF THE FLUORCALCIOBRITHOLITE-FLUORBRITHOLITE-(Ce) IN GABBROIDS
As a result of the study, in monzogabbro from the pre-Jurassic foundation of the Novoportovskoye oil and gas exploration area (southern part of the Yamal Peninsula), fluorcalciobritholite and fluorbritholite-(Ce) – rare earth minerals 7 from the apatite supergroup were established. They form short-prismatic small individuals around fluorapatite crystals and belong to the primary mineral (magmatic) association. This is the first finding of these minerals in gabbroids, which significantly expands our understanding of their occurrence in nature.
