We studied the ore-free and ore-bearing amphibole gabbro of the Shanuch sulfide cobalt-copper-nickel deposit, Kamchatka. The phase sequence of the intrusions injection as well as magmatic origin of their rocks were detailed. The parental compositions of the rocks, their ways of the differentiation and the significance of the ore formation in the petrogenetical process were constructed.
