Unravelling contamination signals in biogenic silica oxygen isotope composition: the role of major and trace element geochemistry
The oxygen isotope composition of diatom silica (δ18Odiatom) provides valuable information for palaeoclimate studies where carbonate proxies are either rare or absent in many lakes and ocean sediments. Unfortunately, mineral and rock fragments found alongside diatoms in most sediments can be problem...
