THE ORIGIN OF FERROMANGANESE SEDIMENTS ASSOCIATED WITH THE TROODOS MASSIF OF CYPRUS

Abstract
Sediments within and immediately above pillow lavas of the Troodos Massif of Cyprus show abnormally high concentrations of iron, manganese, arsenic and copper. Most likely they contain precipitates related to volcanism along a Tethyan rise. In addition, silica has been leached from lavas and has partly remobilized to form chert layers above the ferromanganese sediments. As a result of hydrothermal activity some horizons are enriched in copper, lead, zinc and nickel, and manganese and arsenic have been mobilized in the sediment column.
