Egmont Köhlere leached with a weak base, usually Na.CO., for a period of time (2–5 hours), and aliquots withdrawn over time. The aliquots are then measured for the amount of Si extracted and a least-squares regression is made on the increase in concentration with time to separate the Si extracted from amorphous

Jakob Krarup,Ole Bildendertake the time-consuming task of constructing modern phytolith reference collections for their study regions, their efforts are likely to be rewarded because phytoliths can be useful in the identification of specific taxa. Identifications of some key indicator families and genera should be possib
