Abstract
Gold, arsenic and antimony appear together in hydrothermally altered area. However, Au exists very little in the eastern part of Inuyama-city, although high As concentrations are observed. There might be different mechanism of elemental concentration in As and Au from hydrothermally altered area. In this study, we collected 101 stream sediments in Inuyama-city, Aichi Prefecture, and determine major elements and trace elements that included As ,Sb and Au. We drew the geochemical map of these elements and discuss mobility of elements in Mesozoic and Paleozoic area.
