・電子プローブマイクロアナライザを高性能・高機能化して分析値の精度と確度を高めた.・トリウムやウランを含む鉱物のコンコーダントな分析値を選別する化学的基準を確立して、CHIME年代の確度を高くした.・氷上花簡岩、領家帯ミグマタイト、肥後変成岩、韓国京畿地塊の準片麻岩、中国南東部の花商岩類、中国吉林省の東清花簡岩のCHIME年代を再検討して、地質学的推定年代や同位体年代との矛盾を解明した.矛盾の原因は肥後変成岩と東清花商岩では同位体年代、氷上花商岩と京畿地塊では地質学的解釈、領家帯ミグマタイトと中国南東部花商岩ではCHIME年代にあった.

·High performance·High functionality·High accuracy and accuracy of analysis·The chemical criteria for the selection of analytical values, including the determination of chemical parameters, and the accuracy of CHIME dating, were established. The Huashang rocks in the south and east of China, the CHIME age of the Dongqing Huashang rocks in Jilin Province of China, and the contradiction between geological dating and isotopic dating have been clarified. The cause of this contradiction is the isotopic age of Huashang rocks in the eastern part of China, the geological interpretation of Huashang rocks in the eastern part of China, and the geological age of Huashang rocks in the southern part of China.
