Abstract The North China craton of central Asia is a natural laboratory for investigating early Earth tectonic processes including subduction and large-scale horizontal crustal motions. However, it remains unclear how when the formed from amalgamation several blocks orogens Archean Western Eastern blocks, late Central Orogenic Belt, Paleoproterozoic Northern Margin orogen. In this study, we int...

The Cordillera Real granitoids are a suite of Triassic and Oligocene plutons in the core Eastern Central Andes Bolivia. Their tectonic setting, chemical ore compositions make them part so-called “Inner Magmatic Arc”, which differs from current “Magmatic Arc” located immediately to west. U-Pb SHRIMP data were obtained order constrain crystallization ages. group yielded following results: 239±2 M...
