The Age of Globular Clusters [PDF]
, 1999 I review here recent developments which have affected our understanding of both the absolute age of globular clusters and the uncertainties in this age estimate, and comment on the implications for cosmological models.

SIMS zircon ages and Nd isotope systematics of the 2.2 Ga mafic intrusions in northern and eastern Finland [PDF]
Bulletin of the Geological Society of Finland, 2010 Using the SIMS, ID-TIMS and Sm-Nd isotopic methods and the electron microprobe, we have studied several differentiated mafic intrusions of the c. 2.2 Ga gabbro-wehrlite association (GWA) from four Paleoproterozoic schist belts and the Archean Kuhmo ...

On the deglaciation chronology of the Palivere ice-marginal zone, northern Estonia [PDF]
Bulletin of the Geological Society of Finland, 2012 This paper presents new bio-, litho- and chronostratigraphical evidence from two adjacent sediment sequences of the Tõdva and Saku basins, northern Estonia that refine the age estimate of the Palivere ice-marginal zone and the deglaciation history of ...

Lead and neodymium isotopic results from metabasalts of the Haveri Formation, southern Finland: Evidence for Palaeoproterozoic enriched mantle [PDF]
Bulletin of the Geological Society of Finland, 1999 Tholeiitic metabasalts and coexisting sulphides have been analysed for their Pb and Nd isotopic compositions from the Proterozoic Haveri Formation, which forms the basal unit of the Tampere Schist Belt in southern Finland. Ten whole rock samples analysed

Structural evolution of the Vuotso area, Finnish Lapland [PDF]
Bulletin of the Geological Society of Finland, 2003 The Vuotso area is structurally interesting because the fold interference pattern in rocks of central Lapland changes into thrust-related foliation of the Lapland Granulite Belt.

U-Pb zircon determinations from the Keikyä Breccia and other sites in the Svecofennides: indications of a Svecokarelian protocrust [PDF]
Bulletin of the Geological Society of Finland, 1996 Heterogeneous zircon populations from four different localities within the Svecofennian area in Finland demonstrate that the ca. 1890 Ma old syntectonic granitoids contain older material, probably belonging to the ca. 1950 Ma Svecofennian protocrust, the
