U-Pb zircon data for: Cretaceous plutonic rocks of western Glacier Bay National Park and Preserve
Geochronologic analyses to determine the ages of the plutonic rocks in the Glacier Bay area. Five samples were dated by laser ablation-inductively coupled plasma mass spectrometry U-Pb methods. These analyses contribute to understanding the geologic history of this area. Sample locations and characteristics, along with measured isotopic ratios and calculated ages are provided in CSV format. |
