Oxygen–Carbon and Strontium Isotope Composition in Primary Carbonatites of the World: The Data Summary and Linear Trends

open access: yesРуды и металлы
A statistical regression analysis was performed of a summary of borrowed literary iso- topic data on 176 carbonatite occurrences worldwide (a total of 1829 paired δ18О-δ13С values in primary carbonatites).

Mantle Origin of Oceanic Carbonatites

open access: yes, 2010
Carbonatites are igneous rocks composed of over 50% carbonate minerals. These unusual rocks are generally associated with rift systems but are also found on ocean islands, namely Fuerteventura in the Canary Islands and islands in the Cape Verde chain ...

Assessment of ancylite ore dressability by flotation method

open access: yesЗаписки Горного института
For more than 50 years, most rare earth elements were extracted from carbonatite deposits, which can contain different rare earth phases, but the main extracted minerals are bastnaesite, monazite and xenotime.

Carbonatites in skarn objects of the Urals

open access: yesЛитосфера, 2017
The temperature range of the formation of skarns suggests the melting of limestones in the heat-and-mass transfer columns of the Earth’s crust. The ontogenic analysis of structures of the carbonate rocks in some Ural skarn objects indicates the presence ...
