The Acid-alkali-free Analysis of Quaternary Pollen

LI Xiao-Qiang and DU Nai-Qiu   

Abstract: The acid-alkali-free analysis is a very useful method for extraction of pollen from Quaternary sediments because of its technical simplicity and easiness in operation. The new method does not need the use of acid and alkali as the conventional methoddoes . It has a special feature of short work cycle, owns the advantages of the low pollen destruction, pollution and cost. It is a very powerful method to be used in the high-resolution Quaternary pollen research.

Key words: Quaternary pollen, Acid-alkali-free, Analysis method
