The HGS Chalk Project

Stratigraphic methods, biases and problems

 

Methods

Members of the project group measured exposures in the field, firstly concentrating on inland quarries and then tackling the coastal exposures. Beds were measured to the nearest centimetre and where the thickness of a bed varied the thickest extent was recorded. This of course may lead to an exaggeration of the overall total thickness of the Chalk. the occurrence of fossils in situ was recorded but not normally to species level; we were mostly working on fragmentary remains.

Sources of bias

It was realises that there are a number of sources of bias such as -

Problems encountered

There are some gaps in the sequence -

Biostratigraphy -
