Similar corundum-bearing rocks, which were also presumably formed during subalkaline metasomatism, are known in Tanzania, India, the United States, and other countries. This paper presents the first results of analysis of the corundum-forming Ca-Na metasomatism. Держатели документа: Центральная научная библиотека УрО РАН Доп.точки доступа: Rusinov, V. L.
