We researched mineral composition of the alkaline basalts from section of the Cretaceous oceanic crust on the Kamchatsky Mys Peninsula. These data obtained for paleooceanic assemblage of the Eastern Kamchatka for the first time. Clinopiroxenes from the investigated basalts have composition of the fassaite with high titanium (up to 6.44% TiO2). Hornblende and biotite are also differing high content of titanium. Spinel compositions of investigated basalts are located in the field spinel compositions of alkaline rocks of Hawaiian Islands. The chemical composition of the minerals is corroborating a conclusion about the similarity of the alkaline basalts from Kamchatsky Mys Peninsula with rocks of Hawaiian-Emperor volcanic chain.
