Description

Geo-chemical data of granatoides of the Chukotka tin-ore province are presented. The granatoide massifs are divide into 3 groups. In composition of each group are isolated the granatiodes of the main intrusive phase and leal granite bodies of later intrusive phases. The sequence of group formation is determined by means of rubidium-strontium geo-chronometry (87Sr/86Sr)
