钙质超微化石定量研究方法

TECHNIQUES FOR QUANTITATIVE NANNOFOSSIL STUDIES

针对当前从事钙质超微化石定量研究使用的不同制样方法 ,简要介绍了适用于光学显微镜 (LM)和扫描电子显微镜 (SEM)的传统涂片法、小珠校准法、随机沉淀法和过滤法的主要流程和设备要求 。

Four different preparation techniques (including traditional smear-slide method, microbeads method, settling method and filtering method by using the light microscope (LM) as well as the scanning electron microscope (SEM)) applied to calculating nannofossil abundances quantitatively are briefly described and introduced. The disavantages and advantages of the different techniques are also commented concisely on.
