An international team of Geoscientists met in the middle of October in the city of Xi’an (China) for a workshop in preparation of a potential large-scale scientific project. The “International Scientific Drilling Programme” (ICDP) supports scientists to conduct international drilling projects. The international teams solve questions of high societal relevance, such as the past climate development. One of the next scientific wells might be drilled in central China, in the so-called Weihe basin. The drill is supposed to be about 7,500 m deep, in order to understand the palaeo-climate of the past 50 Mio years in detail. Two scientists of the LIAG have been involved in the workshop, and may join the drilling project. Their contribution would be knowledge in the field of cyclostratigraphy, which gives information upon age and sedimentation rates of rocks. Additionally, petrophysical investigations, by using especially the method of spectral induced polarization, which has been never utilized for ICDP projects before, have been proposed as potential project work.
