How do geologists determine the absolute ages of rocks with radioactive decay? Geologic Time and Dating. Geological dating is the process of estimating the age of different materials. This collection will introduce you to the two major. Radioactive Dating of Minerals. Absolute age dating is based upon the decay of radioactive (unstable) isotopes. At the blocking temperature, the radioactive parent.

Spatial correlation analysis reveals a significant negative correlation between RH AMJ at Mt. Tianmu and Sea Surface Temperature SSTs in the western equatorial Pacific and Indian Ocean. Both observed and reconstructed RH AMJ show significant positive correlations with East Asian and South Asian monsoons from to , which indicate that RH AMJ from Mt. Tianmu reflects the variability of the Asian summer monsoon intensity to a great extent. The summer monsoon has weakened since However, an increase in relative humidity since implies a recent enhancement in the summer monsoon.
