Preliminary research and scheme design of deep underground in situ geo-information detection experiment for Geology in Time

The deep earth, deep sea, and deep space are the main parts of the national “three deep” strategy, which is in the forefront of the strategic deployment clearly defined in China’s 14th Five-Year Plan (2021–2025) and the Long-Range Objectives Through the Year 2035. It is important to reveal the evolutionary process and mechanism of deep tectonics to understand the earth’s past, present and future. The academic connotation of Geology in Time has been given for the first time, which refers to the multi-field evolution response process of geological bodies at different time and spatial scales caused by geological processes inside and outside the Earth. Based on the deep in situ detection space and the unique geological environment of China Jinping Underground Laboratory, the scientific issue of the correlation mechanism and law between deep internal time-varying and shallow geological response is given attention. Innovative research and frontier exploration on deep underground in situ geo-information detection experiments for Geology in Time are designed to be carried out, which will have the potential to explore the driving force of Geology in Time, reveal essential laws of deep earth science, and explore innovative technologies in deep underground engineering.
