Outline of Speleothem Lab

  Under the guidance of Prof. Zhisheng An, the first director of Institute of Earth Environment, Speleothem Lab was established in 1998. It is directed by Prof. Yanjun Cai now. The faculty and staff of this lab have achieved a batch of academic achievements in speleothem related studies since 1998. A series of scientific research papers have been published in Geology, Earth and Planetary Science Letters, Quaternary Science Reviews and so on. The Lab is now equipped with IsoPrime100 mass spectrometer connected with the Dual-inlet and MultiPrep systems, the New wave Micromill and the Olympus fluorescence polarization Microscope BX-60 and other instruments for preprocessing the speleothem sample. In last few years, the speleothem lab have collaborated with various scientific centers in the world, including Isotope Lab in University of Minnesota; Center of Atmospheric Sciences, University of California, Berkeley; Institute for Environmental Study, Australia Nuclear Science and Technology Organization; Institute of Geology and Geophysics, Academy of Uzbekistan. 

Missions:

The Speleothem Lab mainly focuses on extracting high-resolution paleoclimatic and paleoenvironmental informations from speleothem along with other geological, historical and biological records; aims to understand changes and dynamic of Asian monsoon-arid environment and the important climatic events, and also their interactions with globe climate change in the late Quaternary.
