Welcome to Geochemistry Laboratory!

Thank you for your interest in Geochemistry Laboratory, Environmental and Analytical Chemistry, Department of Environmental Biology and Chemistry, Faculity of Science, University of Toyama.

We are studying WATER based on geochemical method to clarify global environment changes and status of environmental pollutions.

Professor, Dr. ZHANG, Jing group:

Clarify the origins and circulation mechanisms of materials in the earth's surface, linking with global environment changes, by using trace element concentrations and isotopic composition.

1. Geochemistry of submarine groundwater discharge and its impact on the costal environment,
2. The origins and long term transposition of anthropogenic material and its impact on the marine ecosystem,
3. Oceanic circulation and variation related to global climate changes,
4. The monitoring of formation mechanisms of chemical synthesis communities in cold seep areas.

Professor, Dr. UEDA, Akira group:

Natural phenomena in hydrosphere and lithosphere are studied geochemically. Stable isotope analyses are applied to understand the behavior and origin of deep-seated fluids associated with magma, oil and natural gas. Also, laboratory and field experiments of rock-water-CO₂ interaction at high temperature are performed to investigate fixation of CO₂ as carbonate minerals.

Assistant Professor, Dr. HORIKAWA, Keiji group:

I am a geochemist and sedimentologist with a particular interest in paloclimate, paleoceanography, and environmental science. My current focus is to understand interaction among ocean, land, and climate, which has controlled the earth's climate for the past 4.6 billion years. I also have an ongoing interest in (1) reconstructing high-resolution records for the past several millennia from peat and lacustrine sediments and (2) applying rare earth elements and their isotopes to understand a hydrologic cycle and to identify recharge areas of underground water in Toyama prefecture.

The groups are studying each other's fields and the laboratory is working under the cooperation of both groups.
