摘　　要：选择合适的制片方法对于研究钙质超微化石十分重要。针对粗颗粒碎屑岩和钻井岩屑,制片时需要使用大量样品的情况,提出包含震荡混合和二次悬浮操作流程的钙质超微化石制片方法。重复实验表明,该方法获得的属种丰度误差一般低于10%,可以满足常规和定量钙质超微化石生物地层和群落分析的需要。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 assem- blage analyses.
