彭松柏 %A 战明国 %A 张业明 %A 邱瑞照 %A 陈富文 %J 地球学报 %D 2000 %I %X The whole rock banded-augen granitic rock samples form Yankai uplifted area are dated Sm_Nd and Pb/Pb isotopically 1414±68Ma and 1388±90Ma respectively. These data indicate that the orogeny took place not only in Caledonian but also in Late Mesoproterozoic, which secms more important and is correlatable with global Grenville orogeny. %K Yunkai area %K Pre-Caledonian granitic rock %K Sm-Nd and Pb/Pb isotopic dating
