Overview

Research shows the late cretaceous chaluo granite formed in a post-orogenic setting, indicating significant tectonic activity.

Key Points

  • Chaluo granite formed in the late cretaceous period, indicating geological evolution in the area.
  • Zircon U-Pb dating reveals crystallization ages of 87 ± 3 Ma, highlighting its geological significance.
  • Elemental geochemistry shows I-type granite characteristics, suggesting processes of fractional crystallization.
  • Tectonic analysis indicates formation due to the northward subduction-collision of the Lhasa block.
