Summary
Abstract: The field environmental geological exploration in Matsue City and
Kanazawa City, as well as, the water quality investigation of river
water at 200 sites have been carried out.From a cultivation experiment
of microorganisms obtained, it was made clear that an enrichment of
manganese and iron occurs in a short time such as several days through
a participation of these microorganisms, and the structural materials
(manganese nodules) similar to a shape of Leptothrix discophora are
formed, and furthermore its process was explained. In addition, the
microstructure and its constitution constituents of river water and
sediment were clarified by an instrumental analysis.
