| Abstract: | New geochemical data are discussed on the magmatic complexes of the Koksharovka alkaline ultrabasic massif of Late Jurassic
age obtained by the ICP-MS method. Based on the first results on rare earth geochemistry of carbonatites and associating pyroxenites
and geological observations, the magmatic origin of the Koksharovka carbonatites was substantiated, and the problems of formation
of accompanying igneous rocks were considered. |
