Trace metal chemistry and silicification of microorganisms in geothermal sinter, Taup Volcanic Zone, New Zealand

摘要

As part of a pilot study investigating the role of microorganisms in the immobilisation of As, Sb, B, Tl and Hg, the inorganic geochemistry of seven different active sinter deposits and Their contact fluids were characterised. A comprehensive series of sequential extractions for a Suite of trace elements was carried out on siliceous sinter and a mixed silica-carbonate sinter.
