Abstract: A suitable preparation technique is essential to calcareous nannofossil studies.Existing methods aim to dealing with small samples with relatively abundant nannofossils.A new technique,which includes mixing via vortex vibration and double suspension,was proposed to handle coarse clastic rocks and drill cuttings when large amount of samples is to be prepared.A reproducibility test showed that the experimental error is better than 10% in terms of taxonomic percentage abundance,satisfying routine and quantitative calcareous nannofossil biostratigraphy and assemblage analyses.
