Major achievements
Dr. Sano has made many world-leading achievements in volcanic and environmental chemistry using volatile elements such as noble gases, carbon and nitrogen, and contribution in uranium-lead dating, trace element geochemistry, etc. In particular, he developed a new method for measuring helium isotopes, and has been involved in research on subduction zone tectonics, earthquakes and volcanism. Using secondary ion mass spectrometry (SHRIMP and NanoSIMS), he invented an ultra-high resolution trace element analysis method for carbonate and uranium-lead dating of phosphate. Using this new analytical method, he discovered the oldest traces of life on the Earth, proposed a new formation age of the lunar ocean, and precisely reconstructed the past marine environment.
