(1999)Clinohumite-bearing parageneses Cal + Dol + Chu 4- Fo + Tr + Phi, Cdl + Dol + Chu + Fo + Phi, Cal + Dol + Chu + Sp, and Cal + Chu + PI + Qtz, referred to the progressive stage of regional metamorphism, have been revealed ...
-
(2001)Results of the detailed petrological study (including mineralogical, petrological, and geochemical characterization and isotopic dating) of Neoproterozoic dike swarms in the southern flank of the Siberian craton are employed ...
-
(1989)In the Kirgiz Tien Shan, hitherto regarded as a classical orthomagmatic granite province, recent work revealed granitoid rocks formed by metamorphic and ultrametamorphic processes. In their geologic position, structure, ...
-
(2004)Highly aluminous xenoliths include kyanite-, corundum- and coesite-bearing eclogites, grospydites and alkremites. These xenoliths are present in different kimberlites of Yakutia but have most often been found in Udachnaya ...
-
(2003)This paper presents the results of investigations of the geochemical and isotopic compositions of komatiites from various Late Archean greenstone belts and structures of the Baltic shield. The analysis of major, trace, and ...
-
(1998)The Onega plateau constitutes part of a vast continental flood basalt province in the SE Baltic Shield. It consists of Jatulian-Ludikovian submarine volcanic, volcaniclastic and sedimentary sequences attaining in places ...
-
(2003)Phase layering in mafic and ultramafic intrusions cannot be explained in terms of convection and crystal accumulation in magma chamber, as vigorous convection of melts enriched in suspended crystals is impossible. Emplacement ...
-
(2004)The blueschist/greenshist Terekta Complex is the only blueschist locality known in the Russian Altai. The Terekta metabasites contain Na and Na–Ca amphibole, actinolite, phengite, epidote, albite, quartz, calcite, magnetite ...
-
(2001)Mineralogical and geochemical evidence indicates that peridotites of the ophiolite complex (spinel lherzolites, spinel harzburgites, dunites, and wehrlites) in Cape Povorotny were produced during a single magmatic episode ...
-
(2006)The tonalite-plagiogranite (tonalite-trondhjemite) association only occasionally occurs in the form of large granitoid bodies, such as the Yenisei Batholith (>500 km2 in area). The granitoids of the Yenisei Batholith belong ...
-
(2006)In the northern Baltic Shield, diorites, monzodiorites, and quartz diorites are constituents of postorogenic granite massifs, the localization of which was controlled by NE- and NW-trending fault zones. The NE-trending ...
-
(2002)The central part of the Voronezh crystalline massif was determined to contain the following three petrochemical types of metapelites: (1) K-poor magnesian and aluminous cordierite–gedrite–anthophyllite schists, (2) K- and ...
-
(2002)The subducted lithosphere is composed of a complex pattern of chemical systems that undergo continuous and discontinuous phase transformation, through pressure and temperature variations. Volatile recycling plays a major ...
-
(2002)The Burakovka layered pluton of basic and mafic rocks is the largest intrusive massif in the Baltic Province composed of Si- and Mg-rich boninite-like rocks. The pluton consists of two individual bodies, each having its ...
-
(2001)The subalkaline magmatism in the western slope of the Urals is an indicator of rifting processes, which accompanied the splitting of the Rhodinia supercontinent at the boundary of the Late Proterozoic and Early Paleozoic. ...
-
(2001)The Lashkerek caldera filled with acid volcanic products is situated in the Kurama Ridge near Tashkent (Uzbekistan). These eruptions of the Late Paleozoic time were predominantly of the explosive type. The erupted complex ...
-
(2006)The Bhopalpatnam granulite belt (BGB) flanks the Pranhita-Godavari (PG) rift basin with ages ranging from 1.6 to 1.9 Ga, representing a major Mesoproterozoic thermal regime in central India. We present here new results on ...
-
(2006)Volcanic rocks of the Lower Devonian Kalatag formation in the Kalatag region, eastern Tianshan are dominated by Na-rich andesite, rhyolite and dacite rocks with less Na-rich basaltic andesite and basalt and minor basaltic ...
-
(2001)The paper discusses the current ideas of regional magnetic anomaly sources and experimental evidence for the formation and behavior of various magnetic minerals within a wide range of pressure, temperature and oxygen ...
-
(Springer, 2012-11)This paper presents results from a study of lava flows that were discharged by Bezymyannyi Volcano at different times, from old (about 3500 years ago) to recent ones (1985–1989). We provide detailed descriptions of the ...
