A New Multi-Mineral Age Reference Material for40Ar/39Ar, (U-Th)/He and Fission Track Dating Methods: The Limberg t3 Tuff

“…An increasing number of studies have applied a combination of several dating techniques (e.g., Blythe et al 2000, Reiners et al 2000 to reveal a detailed insight into near-surface cooling paths and topographic evolution within various geological settings. The removal of material from the Earth's surface, which leads to cooling within the corresponding rock column, can be quantified at several crustal levels by a range of chronometers, such as the K/Ar system (e.g., Lange et al 2000), the fission track (FT) method (e.g., Gunnell 2000) and the recently established (U-Th)/He method (for review, see Farley 2002). Most of the produced ages from such studies lie within the late Tertiary and Quaternary, and thus require a set of reference materials of corresponding age.…”
