Energy dispersive X-ray spectrometry is applied to the study of thinly laminated organic sediments of the iron-meromictic Lake Valkiajärvi, Finland. Si, Fe, Ca, K, S, (and Cl as an artefact) are present in detectable quantities. It is concluded that the main reason for the occurrence of such annual laminations (i.e. varves) in this lake is the seasonal variation in the deposition of mineral matter. Iron remains low throughout the year and does not play any important role in varve formation.
