521 Tectonochronology: New Methods, Theories, and Some Cases
New theories and methods in tectonochronology research affect several important scientific topics: formation of syn-kinematic minerals in deformation, sedimentation, metamorphism, and magmatism; development of systematic methods of dating deformation and their use; criteria for dateable minerals and methods for direct and precise dating; the relationship between mineral formation/evolution and isotope chronology; and influences of strain and fluid on isotopic diffusion. We also present some case studies through these new approaches on syn-kinematic growth mineral dating and strain analysis on the isotopic diffusion, with a particular focus on interdisciplinary studies aimed at linking tectonic chronologies to tectonic stress, temperature, fluid circulation, and exchanges of minerals during various deformation conditions. We will also present cases from Chinese geology that refer to dating of sedimentation, metamorphism, tectonic evolution, and environmental change.
