The paper presents the results of Brouton Bay (Simushir Island, the Kurile Islands) echo-sounding
investigations had been made in July 2011 during complex scientific and research expedition of FSBSO
Institute of Marine Geology and Geophysics FEB RAS by means of «Lowrance LMS-527cDF iGPS» echo
sounder with oscillator frequency of 50/200 kHz and built-in 12-channel GPS receiver. We worked out
57 km of depth sounding profiles and constructed Brouton Bay bathymetric map and 3D-model. The bay
maximum depth comprised 250 m and the caldera total depth comprised about 700 m. Submarine slopes
of the bay have an angle ~ 15-25° to the depths of 200-220 m, then they have an angle of 5-10°to the vast
nearly flat bottom at the depths of 240-250 m.

Isotope-geochemical material for Pliocene-Quaternary volcanoes of the Kamchatka region is generalized on a cartographic basis. The Sr-isotope anomalies of moderate and elevated radiogenicity, geochemically confirmed, are spatially conjugated. This made it possible to interpret these anomalies not only as a reflection of mantle plume material in the composition of volcanic rocks, but also of its hybrid environment, as a consequence of plum-lithosphere remobilization. The presence of multi-directional geochemical trends made it possible to propose the concept of moving boundary values for the composition of indicator rocks of the intraplate type and adakites, which significantly expanded the possibilities of their diagnostics. The isotope-geochemical heterogeneity of basaltoids of the region is generally determined by the peculiarities of concentration of rocks with intraplate and adakite geochemical characteristics, which allows considering the asthenospheric diapirism as the main factor of petrogenesis of Pliocene-Quaternary volcanism in Kamchatka.

The paper presents new geological and isotope-geochemical data on rock composition from the head of the Kikhchik River, the outer NW part of Miocene-Pliocene volcanic belt of Central Kamchatka. The authors obtained age characteristics (40K−40Ar dates): 9.8 and 9.1 Ma for Kecheva massif and 8.3 and 7.8 Ma for Aopchi cones. New data on ages and analytical materials allow substantial updating our understanding of the rock composition from this volcanic belt as well as the beginning of volcanic activity. The authors revealed complex rocks, both completely identical to closely located volcanic manifestations (Kecheva) and abnormally enriched with Rb, Pb, Ba, Zr, Hf, Nb, U, Th and radiogenic Sr Aopchi, Kabanikha, littoral cones. The origin of these anomalous volcanites was likely caused by the partial melting of the mantle source close to the Sp- peridotite metasomatically reworked by the processes that may relate both to dehydratation of the subducting oceanic plate, and by the effect from the asthenospheric diapir.

The evolution of the Quaternary Kekuknai volcanic massif (the western flank of the Sredinnyi Range in Kamchatka) has been subdivided into five stages: (I) the pre-caldera trachybasalt- basaltic andes- ite, (2) the extrusive trachyandesite-trachydacite, (3) the early trachybasalt, (4) the middle hawaiite- mugearite (with occasional occurrences of basaltic andesites), and (5) the late trachybasalt-hawaiite- mugearite (with occasional andesites) of areal volcanism. On the basis of petrologic data we identified the island arc and the intraplate geochemical types of rocks in the massif. The leading part in petrogenesis was played by dynamics of the fluid phase with a subordinated role of fractional crystallization and hybridism. Successive saturation of rocks with the fluid phase in the course of melt evolution stopped at the time of caldera generation when most fluid mobile elements and silica had been extracted. The geological and petrologic data attest to the formation of the massif in the environment of a backarc volcanic basin during the beginning of rifting with active participation of mantle plume components.

The Kekuknai massif was formed in the course of tectono-magmatic activity that involved the origin of a shield volcano and a caldera depression with associated emplacement of extrusions that terminated in intense post-caldera areal volcanism. The mineralogical compositions of the massifs rocks have been considered in detail. The use of previously known and newly developed indicator properties of rock-forming minerals allowed the reconstruction of the general picture of the magmatic melt evolution and conditions of rock crystallization (various fluid and water saturation levels, as well as the oxidation state of the system). Essentially island-arc or intraplate characteristics of the massif s rock compositions are found at different stages of development of a single fluid-magmatic system. Decompression evolution of the parent deep-seated basanitic magma occurred via occurrence in intermediate magma chambers of daughter magmas of trachybasalt (pre-caldera stage) or hawaiite (areal volcanism) composition. Subsequent emanate-magmatic differentiation of these melts, combined with crystallization differentiation under changing P-T-f0l conditions, resulted in the formation of the entire diversity of the Kekuknai rocks
