[HTML][HTML] Zircon ages in granulite facies rocks: decoupling from geochemistry above 850° C?

BE Kunz, D Regis, M Engi - Contributions to Mineralogy and Petrology, 2018 - Springer
Granulite facies rocks frequently show a large spread in their zircon ages, the interpretation
of which raises questions: Has the isotopic system been disturbed? By what process (es) …

Subduction initiation at the Solomon back‐arc basin: Contributions from both island arc rheological strength and oceanic plateau collision

L Wang, L Dai, W Gong, S Li, X Jiang… - Geophysical …, 2022 - Wiley Online Library
It is generally accepted that the subduction polarity reversal (SPR) results from the strong
