Crustal Ore-Bearing Carbonatites-Kuldimites of the Byrranga Mountains, Taimyr Peninsula: A Model for Mantle-Crust Interaction

Abstract During small-scale geological survey (2004–2017) and the preparation of the State Geological Maps at a scale of 1 : 1 000 000 (third generation) in the Byrranga Mountains of the Taimyr fold system, areas of the distribution of Middle–Late Triassic crustal carbonatites-kuldimites were identified. Patterns of their distribution, petrographic, mineralogical, isotope-geochronological, and isotope-geochemical features allow us to outline a model for the origin of ore-bearing carbonatites and fluidolites during the interaction of plumogenic mantle magmas and salt- and water-saturated upper crustal carbonate rocks in intermediate chambers.
