最近对大阪湾粘土沉积物进行的一项微结构调查显示，存在着丰富的微化石，特别是在海相层中，这似乎直接影响着沉积物的微结构框架，并最终影响其岩土行为。微体化石作为一种结构成分，当大多数集合体间孔隙空间关闭时，提供了高压缩性。此外，它们还会在物理化学性质的测量上引入一些偏差。关键词：显微结构、孔隙度、阿特伯格极限、压缩性、矿物学、微化石。
A recent microstructural investigation of Osaka Bay clay sediments has revealed the presence of abundant microfossils, particularly in the marine layers, which appear to influence directly the microstructural framework of the sediments and eventually its geotechnical behaviour. The microfossils act as a structural component which provides a high compressibility when most of the interaggregate pore space is closed. In addition, they can introduce some bias on the measurements of physicochemical properties.Key words: microstructure, porosimetry, Atterberg's limits, compressibility, mineralogy, microfossils.
