FAR EASTERN ILMENITE AND MAGNETITE MAGMATIC ROCKS

E.A. Konovalova, L.F. Mishin, Yu.V. Taltykin

Аннотация


Ilmenite magmatism is characteristic of ore deposits, and it is absent in magnetite-series rocks. Modern methods in Redox conditions mapping can be used to identify promising areas for  tin deposits prospecting.

The redox – conditions maps were made, and it was determined the boundaries of ilmenite and magnetite magmatism for the Far Eastern magmatic structures of Eastern Yakutia, the Mongol-Okhotsk western part , and Sikhote-Alin orogenic belts.
