生物地层学使特定的地层能够得到一个独特的地层地址，可用于确定进行原位测试和收集测试样品的层位。这在细粒矿床中工作时特别有价值，其中地层位置不容易仅通过岩性识别，并且允许使用任何岩土工程值和性能的数据库，而不必担心将一个地层与另一个地层混淆。在伦敦粘土地层中进行施工及其辅助研究，需要一种准确、快速的方法，以厘米的精度识别地层，并从中获得岩土工程数据。本文以伦敦的伦敦粘土层为例，说明了生物地层学的原理，这种方法适用于大多数沉积地层。本文介绍了一个在伦敦使用的生物地层学资料的例子。
Biostratigraphy enables specific layers of strata to be given a unique stratigraphic address that can be used to identify the horizons in which in situ tests are conducted and from which samples for testing are collected. This is particularly valuable when working in fine-grained deposits, where stratigraphic position is not easily recognised by lithology alone, and permits any data bank of geotechnical values and performance to be used without fear of confusing one stratigraphic layer with another. Construction in the London Clay Formation, and its supporting research, has necessitated an accurate and speedy method for identifying, with a precision of centimetres, the stratigraphic layer from which geotechnical data have been obtained. The principles that enable biostratigraphy to be used for this purpose are explained and illustrated with reference to the London Clay Formation in London: this approach can be used in most sedimentary strata. An example of biostratigraphic data used in London is presented.
