Description Distribution of Hg and other trace elements from Devonian-Carboniferous boundary The highest Hg, Hg/TOC, Hg/Al, and Hg/Fe values bellow and in the Hangenberg Events Anomalous Hg was not simply derived from the increased deposition of organic carbon. Both sections were influenced by widespread hydrothermal and volcanic activity. Hg enrichment caused by local hydrothermal and volcanic activity and redox variations
