Core Viewpoint - The "Weihe Basin Deep Drilling Project" has officially commenced, aiming to conduct environmental drilling to study the co-evolution of the lithosphere, hydrosphere, and biosphere, and to assess geothermal and helium resource potential in response to national deep earth strategic needs [1][3][4]. Group 1: Project Overview - The project is a collaboration initiated by the Chinese Academy of Sciences with international scientists from the USA, Switzerland, and Australia [3]. - It consists of two phases: the first phase aims to obtain 3,000 meters of sedimentary strata, while the second phase will target over 10,000 meters of complete sediment records [3][4]. - The Weihe Basin is recognized for its thick sedimentary deposits, making it an ideal location for studying climate and environmental changes over the Cenozoic era [3][4]. Group 2: Scientific Goals - The project seeks to reconstruct hydrological and climatic variations in East Asia since the Late Miocene and to explore the coupling relationship between monsoon evolution and the uplift of the Tibetan Plateau and Qinling Mountains [3][4]. - It aims to establish a "golden nail" for terrestrial climate global environmental changes during the Cenozoic [3]. Group 3: Support and Implementation - The project has received strong support from various local government and scientific institutions, including the Shaanxi Provincial Department of Natural Resources and the Weinan Municipal Government [6]. - The first phase of drilling will be jointly implemented by the Chinese Academy of Sciences and the Shandong Third Geological and Mineral Exploration Institute [6].
