(Table 1) Age determination of basalts from DSDP Hole 30-289
The Pacific plate has undergone a substantial northward displacement during the late Mesozoic and the Cainozoic. Here we give additional documentation for such motion based on... -
Potassium and argon concentrations and age determination of ODP Site 125-782 ...
K-Ar whole-rock ages have been obtained for 30 samples from Sites 782 and 786, Ocean Drilling Program Leg 125 in the Izu-Bonin (Ogasawara) forearc region. They form a trimodal... -
K-Ar data for whole-rock basalts at ODP Hole 105-647A (Table 1)
Alteration of basalt samples in the basement rocks of Site 647 produced a range of K-Ar ages from 35 to 71 Ma. Microprobe data indicate that an alteration phase contributes... -
(Table DR1) Argon isotope data and dating for individual >63 µm amphibole gra...
Variations of global and regional silicate weathering rates and paleo-ocean circulation patterns are estimated by using radiogenic isotope records, but the effects of changes in... -
(Table S3) Argon geochemistry of minerals from Hawaiian-Emperor seamounts
Position of the seamounts are estimated. The parameter J, a measure of the extent of conversion of 39K to 39Ar, was determined for each sample by analyzing co-irradiated Fish... -
