摘要
In kersantite and spessartite dikes of Chetlas Kamen' in Central Timan among accessory garnets, that are rather rare in lamprophyres, there was discovered few and for the first time high-majorite pyrope garnet with majorite minal Mg3Fe2[SiO4]3 (26-42%), similar to majorite garnet originating from a meteorite. Majorite discovered in Coorara meteorite is very rare in the terrestrial rocks. As it is shown, there is 18% pyroxene admixture in original analysis of maj orite that is why a surplus of S i appeared in its formula. In rocks, where majorite garnet was found, there are also revealed microcrystalline diamonds.
