MELT INCLUSIONS IN MINERALS OF ALLIVALITES OF THE KURIL-KAMCHATKA ISLAND ARC

Frolova T.I.; Plechov P.Yu.; Tikhomirov P.L.; Churakov S.V. (2001)

The genesis of low-silica (generally olivine-anorthite) inclusions in volcanic rocks of the low-K tholeiitic island-arc series is a matter of active discussion. The study of melt inclusions in the major minerals of allivalites ...
MINERALOGY, GEOCHEMISTRY AND PETROGENESIS OF KURILE ISLAND-ARC BASALTS

Bailey J.C.; Frolova T.I.; Burikova I.A. (1989)

Whole-rock (major- and trace-element) and mineral chemical data are presented for basaltic rocks from the main evolutionary stages of the Kurile island arc, NW Pacific. An outer, inactive arc contains a Cretaceous-Lower ...
STRONTIUM ISOTOPE VARIATIONS IN LOWER TERTIARY-QUATERNARY VOLCANIC ROCKS FROM THE KURILE ISLAND ARC

Frolova T.I.; Bailey J.C.; Larsen O. (1987)

Average 87Sr/86Sr ratios for lavas from Quaternary and Pleistocene volcanoes of the Kurile island arc, NW Pacific, decrease from 0.7035 in the south to 0.7032 in the north. The northern Kuriles are characterised by K2Oricher ...
VARIATIONS OF COMPOSITIONS OF VOLCANIC ROCKS OF THE KURILE ISLAND ARC IN THE LIGHT OF DATA ON STRONTIUM ISOTOPES

Frolova T.I.; Bailey D.K.; Larsen O. (1987)

The authors present their analysis of new strontium-isotope data on 88 volcanic rock samples from the KIA (Kurile Island Arc) and on 10 from the Ksudach volcano, southern Kamchatka. The strontium-isotope ratios were measured ...
