      　　各位老師和同學(xué)：
      　　應徐義剛院士邀請，美國加州大學(xué)戴維斯分校尹慶柱教授訪(fǎng)問(wèn)我所，并將于下周一上午做“同位素室學(xué)術(shù)報告”2019年第21次報告。歡迎大家參加并積極參與討論！
      　　Topic: ID-TIMS high precision U-Pb geochronology applied to Snowball Earth, REE mineralization, and Speleothems (carbonate cave deposits)
      　　Speaker: Prof. Qingzhu YIN (UC Davis, USA)
      　　Time: 10:00 AM, July 15th (Monday)
      　　Place:
      　　Conference Room 701 of Main Building
      　　Brief Introduction of the Speaker:
      　　Prof. Qingzhu Yin is a world famous geochemical and planetary scientist. His research focuses on the following aspects: using extinct radioactivity and general isotopic anomalies in the early solar system recorded in primitive meteorites as a tool to study the time scales and site of nucleosynthesis, the time of formation of the solar system and planetary differentiation; isotope and trace element geochemistry with applications to crust-mantle evolution; heavy metal stable isotope fractionation in low temperature environments on planetary surfaces or in biological systems using newly emerging high precision mass spectrometry techniques; the development of associated experimental techniques involving high precision mass spectrometry and ultra-clean sample processing in Class-100 clean laboratories for isotope analyses.
