Environmental Geology Lab
Machine-translated · View original
The lab studies water-rock reactions, from how ore deposits form to how waste is disposed of.
AboutAbout the lab
Thinking about resources and the environment through water-rock reactions.
The Environmental Geology Lab studies water-rock interactions in natural environments, with the goal of applying that understanding to engineering.
The lab works to gain geological insight into rare metal and base metal ore deposits and to clarify the properties of the minerals contained in ores.
To dispose of excavation muck from mine development and radioactive waste with minimal environmental impact, the lab also studies the behavior of toxic elements.
The lab conducts fieldwork in countries across Africa and Asia, as well as at sites throughout Japan.
Key terms
- Ore deposit
- An underground location where useful elements such as metals are concentrated more densely than in the surrounding rock
- Rare metals
- Metals that exist in small amounts or are difficult to extract. They are used as materials for electronic devices, batteries, and more
- Excavation muck
- Unusable rock and soil produced when digging a mine or tunnel
NewsLab news
Assistant Professor Ishida received the Research Encouragement Award (Society of Resource Geology)
A paper by Professor Otake and colleagues was published in Resource Geology
A paper by Professor Otake and colleagues was published in Applied Geochemistry
Assistant Professor Kikuchi received the Encouragement Award (The Clay Science Society of Japan)

ResearchResearch themes
A sustainable society requires resource circulation systems that continuously develop and use earth resources such as metals and energy. The lab takes on a wide range of environmental geology topics from two sides: the geology and minerals of ore deposits, and the behavior of toxic elements involved in waste disposal.
