Description: Radiography superimposed on a photography from Lake Szurpily after oxidation of the sediment surface (scale to the right in cm). The radiography was obtained with a vertical resolution of 400 µm on a split core half (radiated thickness: ~3 cm). Both images document the very well preserved record of annually laminated sediments.
Picture Type: radiographic

Description: Varve structures of four different depth intervals in Lake Szurpiły in Poland. All depth intervals document a similar varve composition: thicker and pale laminae are composed of calcite, whereas thinner and dark laminae are composed of organic matter and minerogenic detritus (varve couplets are indicated to the right by dark and white bars). Note the increasing varve thickness over time that result from changes in sediment accumulation rates during the Holocene.
