文摘
- •
Most of the conodont (U–Th)/He dates are younger than the depositional age.
- •
Peak temperatures ≤90 °C caused He loss from the conodonts
- •
Whole conodont platforms yield the youngest and most reproducible (U–Th)/He dates.
- •
Negative date-U and date-Th correlations for remainder of data are due to U–Th loss.
- •
Whole platforms and higher U–Th material are best targets for He dating.
