Comments | This sample has cracks that take up approx. 2 mm. Using the average growth rate of each cycle in our peak fitting chronology, this makes up about 5 to 6 years of missing data. | T2 missing latest year (1991), T1 has extra cycle at 10.25 mm | Chronology falls within the age constraints of U-Th dates | ||||||
