Research subjects of this laboratory are (a) the past and (b) the future of the earth. (a) Knowledge of the past earth environment is needed to be understanding nature of material and energy circulation in our planet For
understanding of the past earth, we investigate marine and land sediment and sedimentary rocks by the several methods: geology, environmental geology, sedimentology, geochemistry, and geochronology.
Especially, we develop and apply original processing and instrument of non-destructive scanning technology called " TATSCAN". (b) For predicting and planning of our future of the earth, it is necessary to investigated sustainable development not only for natural environment but also for human society. We investigate future model of self-sustainable social system especially based on renewable energy such as, solar,
wind, water, and biomass.
