Initial Rifting Age of the Nearly N–S Rifts in Southern Tibetan Plateau: New Evidence from the Age limit of the Early Sediments

<正>Objective The nearly parallel N–S-trending rifts in southern Tibet represent the E–W extension of the Tibet Plateau.Most data which constrained the age of the extensional deformation come from isotopic dating of the dikes probably related to the activity of the nearly N–S faulting and micas from hydrothermal activity and the lowtemperature thermochronology of plateau uplift.Previous
