Scope 
The International Ocean Discovery Program (IODP) has established the "2050 Science Framework: Exploring Earth by Scientific Ocean Drilling" as a guideline for 2024 and beyond. The International Continental Scientific Drilling Program (ICDP) has already launched a new science plan, "the ICDP Science Plan 2020-2030". Thus, hard rock drilling science is about to enter the next phase. Therefore, drilling proposals from a new perspective and the production of scientific results based on existing drilling projects are expected. In this session, we invite presentations on the scientific results of "hard-rock" such as continental drilling, deep-sea drilling, on-land geological investigations of ophiolites and experimental studies. The session is intended to be interdisciplinary, including the fields of geophysics, geochemistry, petrology, engineering, and biology. This session is organized by the Hard-rock Drilling Science Focus Group.
