Welcome to the Department of Geosciences


"Geosciences" is a discipline for interdisciplinarily recognizing the actual condition of the Earth from the past to the present and building knowledge and technology for predicting its future. To understand the feature of the Earth, we clarify the rules of phenomena that occur due to various activities interacting with the physical and chemical processes of the Earth's materials. Therefore, it is necessary to investigate the history of the Earth as a system. These are the basic knowledge for understanding the current global environment, closely linked to human activity and survival. Furthermore, it is required to understand the global environment and apply the results and disseminate and return them to the community.
     In our department, we investigate the formation and evolution of the Earth from the current environment and history. Based on the results, we respond to social demands such as solving global environmental problems and predicting and countermeasures for natural disasters. The educational goal is to develop human resources who can do it.

     It is crucial to create a wide range of natural sciences and technology knowledge, apply these to geology, and think from multiple and global perspectives. In this department, we will train students in theoretical and experimental methods for grasping the environment and evolution of the Earth in a multifaceted and time-series manner, field research techniques, and the ability to convey the obtained knowledge accurately. In addition, we will develop human resources who can contribute to society widely by acquiring problem-solving skills in various specialized fields.

GeoLogoOur Academic Field

Our department consists of the following 2 fields and 7 laboratories.

Environmental Geosciences

Quaternary Research laboratory


We research natural environmental records in the strata and anthropogenic effects on nature in the newest geological era (Quaternary), including the relationship between nature and humans from the past to the present.


Staff:   Muneki MITAMURA,    Jun INOUE

Geophysics laboratory


To understand the crustal movements occurring on the Earth, we observe and analyze the structure of natural fault rocks related to seismic activity and fault motion. We also conduct laboratory experiments using fault rock simulation materials, and numerical simulations based on these results.


Staff:   Tetsuro HIRONO,    Junichi FUKUDA

Geoinformatics laboratory


From the viewpoint of information science, we use 3D geological model creation and visualization methods, GIS (geographic information system), artificial satellite image analysis, AI (artificial intelligence), etc. In addition, we are researching to understand the Earth's surface features.


Staff:   Venkatesh RAGHAVAN,    Tatsuya Nemoto

Natural Hazards Geoscience laboratory


From the viewpoint of geology, we are researching natural phenomena such as earthquakes, eruptions, and landslides and their accompanying events. In addition, we aim to contribute to disaster mitigation and develop human resources to play an active role in the disaster response.


Staff:   Daisuke MIURA,    Mitsuru OKUNO,    Kazuhiko ISHII

Earth Evolution Sciences

Mineralogy laboratory


Minerals are naturally formed crystalline substances. By examining minerals, we can obtain various information about the constituents of the Earth. Especially, our laboratory is studying minerals using X-ray/electron diffraction, electron microscopy, and different spectroscopic methods.


Staff:    Keiji SHINODA,    Yusuke SETO

Petrology laboratory


We clarify the formation and evolution process of the crust and mantle through field surveys and physical and chemical analysis of collected rock samples. In particular, we are paying attention to the fault process of the continental crust and the mantle process recorded in volcanic rocks.


Staff:    Takamoto OKUDAIRA,    Tetsuya SAKUYAMA

Geohistory laboratory


Based on the geological formations and fossil records of the Earth's surface layer, we are researching the unique phenomena of each geological period and the transition of the global environment from the past to the present.
