Description
In this study we investigate the cosmogenic neon component in olivine samples from a vertical profile in order to quantify muogenic 21Ne production in this mineral. Samples were collected from an 11 m thick Eocene basalt profile in the Eastern Highlands of southeastern Australia. An eruption age of 54.15 ± 0.36 Ma (2σ) was determined from ⁴⁰Ar/³⁹Ar step-heating experiments (n = 6) on three whole-rock samples. A ³⁶Cl profile on the section indicated an apparent steady state erosion rate of 4.7 ±...[Show more]
