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 1) Argon dating of ash layers from DSDP Hole 18-178
Ash layers from Deep Sea Drilling Project site 178 in the northeast Pacific Ocean have been dated by the 40Ar-39Ar stepwise heating technique to resolve published discrepancies... -
(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... -
K-Ar dating of magmatic rocks from the Urup Island, Kuril Island Chain
An isotope-geochronological study of Neogene-Quaternary igneous rocks from the Urup Island (Greater Kuril Ridge) was carried out. It was established that magmatic activity in... -
