Trace Gold Reveals Tree's Past
June 14, 2005
Using a new method to detect trace elements in tree rings, researchers at Cornell University and Penn State noticed elevated amounts of gold in specific rings and correlated several of the bands to a number of volcanic eruptions over the past 500 years.
Penn State nuclear engineer Kenan Unlu, Cornell tree-ring expert Peter Kuniholm and their colleagues believe they can use the technique not only to confirm known eruptions and other phenomena, but also to detect those events when other climatic and geologic records are missing.
