Abstract Fluorcalciobritholite and fluorbritholite-(Ce)—rare-earth minerals from the apatite supergroup—have been found in the course of the study in monzogabbro from the pre-Jurassic foundation of the Novoportovskoye oil and gas exploration area (southern part of the Yamal Peninsula). They form short-prismatic small individuals around fluorapatite crystals and belong to the primary mineral (magmatic) assemblage. This first finding of these minerals in gabbroids significantly expands our understanding of their occurrence in the nature.

首次在辉长岩中发现氟钙闪石和氟闪石-(Ce) 矿物

摘要 在 Novoportovskoye 油气勘探区（亚马尔半岛南部）侏罗纪前地基的二辉长岩中，在研究过程中发现了磷灰石超群的稀土矿物氟钙闪石和氟闪石-（Ce）。 ）。它们在氟磷灰石晶体周围形成短棱柱状小个体，属于原生矿物（岩浆）组合。在辉长岩中首次发现这些矿物质极大地扩展了我们对它们在自然界中存在的理解。
