摘要

本文提出的技术在透射光下揭示钙质和凝集有孔虫的内部形态，有助于分类鉴定。它涉及通过在油浸泡期间应用真空或高温来消除测试中的气泡，以及随后在兼容的QSMM热塑性塑料中安装油澄清测试。该技术快速，无损，允许内部查看大型测试，特别适用于难以薄切片的小型测试。该技术已被用于安装其他微化石，如多胱氨酸放射虫。

A new technique for observing the internal morphology of foraminiferal tests in transmitted light

The technique proposed herein reveals the internal morphology of calcareous and agglutinated foraminifers in transmitted light, aiding in taxonomic identifications. It involves eliminating air bubbles inside tests through the application of a vacuum or high heat during oil immersion, and the subsequent mounting of the oil-clarified tests in compatible QSMM thermoplastics. The technique is rapid, nondestructive, allows internal viewing of large tests and is especially useful for small tests that are difficult to thin section. The technique has been used for mounting other microfossils, such as polycystine radiolarians.

期刊介绍： The Journal of Micropalaeontology (JM) is an established international journal covering all aspects of microfossils and their application to both applied studies and basic research. In particular we welcome submissions relating to microfossils and their application to palaeoceanography, palaeoclimatology, palaeobiology, evolution, taxonomy, environmental change and molecular phylogeny. Owned by The Micropalaeontological Society, the scope of the journal is broad, demonstrating the application of microfossils to solving broad geoscience issues.
