Geochemical mapping in Shikoku, southwest Japan

► Geochemical mapping in a fore-arc area was conducted using stream sediments. ► Areas with higher values of mafic elements are distributed along the axis of Shikoku. ► High values reflect mafic–ultramafic components in metamorphic rocks and accretionary complexes. ► These mafic–ultramafic component...

Description
Summary:► Geochemical mapping in a fore-arc area was conducted using stream sediments. ► Areas with higher values of mafic elements are distributed along the axis of Shikoku. ► High values reflect mafic–ultramafic components in metamorphic rocks and accretionary complexes. ► These mafic–ultramafic components had possibly originated as oceanic rocks. ► Positive anomalies of chalcophile elements near mineral deposits and fault zones are detected. Geochemical mapping of Shikoku in the SW Japan Arc was conducted using stream sediments (
