Radiogenic age and isotopic studies: Report 2

, 1988
Numerical error analysis is applied to typical 40Ar/39Ar data. It extends previous error treatments to al! possible variables used in the calculation of ages of samples and shows that in some cases minor corrections may contribute significantly to age uncertainties.

Radiogenic age and isotopic studies: report 7

, 1993
Granulite facies ortho- and paragneisses and felsic intrusive rocks form the crystalline core of the Boothia Uplift, which extends northward from Boothia Peninsula into the Arctic Archipelago. The rocks dated come from northern Boothia Peninsula, western Somerset Island, and eastern Prince of Wales Island, between 71 °N and 74°N.

Water mass transformation in the Barents Sea inferred from radiogenic neodymium isotopes, rare earth elements and stable oxygen isotopes

, 2018
Nearly half the inflow of warm and saline Atlantic Water (AW) to the Arctic Ocean is substantially cooled and freshened in the Barents Sea, which is therefore considered a key region for water mass transformation in the Arctic Mediterranean (AM ...
