PETROLOGY AND GEOCHEMISTRY OF CRUSTALLY CONTAMINATED KOMATIITIC BASALTS FROM THE VETRENY BELT, SOUTHEASTERN BALTIC SHIELD: EVIDENCE FOR AN EARLY PROTEROZOIC MANTLE PLUME BENEATH RIFTED ARCHEAN CONTINENTAL LITHOSPHERE

Puchtel I.S.; Haase K.M.; Hofmann A.W.; Chauvel C.; Kulikov V.S.; Garbe-Schönberg C.D.; Nemchin A.A. (1997)

New isotope and trace element data are presented for komatiitic basalts and a related peridotite Vinela Dike from the large Vetreny Belt in the southeastern Baltic Shield. The MgO contents of the erupted and intruded magmas ...
PETROLOGY OF MAFIC LAVAS WITHIN THE ONEGA PLATEAU, CENTRAL KARELIA: EVIDENCE FOR 2.0 GA PLUME-RELATED CONTINENTAL CRUSTAL GROWTH IN THE BALTIC SHIELD

Puchtel I.S.; Hofmann A.W.; Haase K.M.; Arndt N.T.; Kröner A.; Kulikov V.S.; Kulikova V.V.; Garbe-Schönberg C.D.; Nemchin A.A. (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 ...
THE RELATIONSHIP BETWEEN THE AGE OF THE LITHOSPHERE AND THE COMPOSITION OF OCEANIC MAGMAS: CONSTRAINTS ON PARTIAL MELTING, MANTLE SOURCES AND THE THERMAL STRUCTURE OF THE PLATES

Haase K.M. (1996)

On the basis of different proportions and chemical compositions of shield and post-shield magmas, three types of oceanic intraplate volcanism appear to exist. The average SiO2 contents of primitive melts of most Pacific ...
