Reiners P.W.; Farley K.A. (1999)We have explored the diffusivity characteristics of radiogenic He in titanite (sphene) and have developed analytical techniques for (U-Th)/He dating of this mineral. Results of incremental He outgassing experiments performed ...

LENGTH SCALES OF MANTLE HETEROGENEITIES AND THEIR RELATIONSHIP TO OCEAN ISLAND BASALT GEOCHEMISTRY Kogiso T.; Hirschmann M.M.; Reiners P.W. (2004)The upper mantle is widely considered to be heterogeneous, possibly comprising a “marble-cake” mixture of heterogeneous domains in a relatively well-mixed matrix. The extent to which such domains are capable of producing ...

Reiners P.W.; Ehlers T.A.; Zeitler P.K. (2005)In one form or another, geochronologists have been practicing thermochronology, the use of radioisotopic dating to constrain thermal histories of rocks and minerals, for over 40 years. Building from lessons learned over ...

Hourigan J.K.; Brandon M.T.; Reiners P.W.; Solov'ev A.V.; Ledneva G.V.; Garver J.I. (2004)The isotopic thermochronological study included the U-Pb (SHRIMP) and fission-track dating of zircon and fission-track and (U-Th)-He dating of apatite from syenite intrusions cropping out in the eastern slope of the Sredinnyi ...

Hourigan J.K.; Reiners P.W.; Brandon M.T. (2005)Both theoretical and empirical evidence shows that intracrystalline U-Th heterogeneity in zircon can lead to biases in (U-Th)/He ages if not accurately accounted for in a-ejection corrections. We present a model for age ...

Reiners P.W.; Spell T.L.; Nicolescu S.; Zanetti K.A. (2004)(U-Th)/He chronometry of zircon has a wide range of potential applications including thermochronometry, provided the temperature sensitivity (e.g., closure temperature) of the system be accurately constrained. We have ...
