(Table 1) Apparent ages from 40Ar/39Ar heating steps for DSDP Hole 72-516F ba...
Submarine basalts are difficult to date accurately by the potassium-argon method. Dalrymple and Moore (1968) and Dymond (1970), for example, showed that, when the conventional... -
Isotopic-geochemical features of spontaneous gases from mud volcanoes in East...
Isotopic-geochemical study revealed presence of mantle He (3He/4He up to 223x10**-8) in gases from mud volcanoes of Eastern Georgia. This fact confirms that the Middle Kura... -
(Table S1) Age determination of Emperor Seamounts basement
The Hawaiian-Emperor hotspot track has a prominent bend, which has served as the basis for the theory that the Hawaiian hotspot, fixed in the deep mantle, traced a change in... -

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 T3) Ar40/Ar39 incremental heating ages of ODP Leg 180 dolerites
Ages are reported relative to biotite monitor FCT-3 (27.84 ± 0.12 Ma), which in turn is calibrated against hornblende Mmhb-1 (520.4, Samson and Alexander, 1987). Calculations...
