We recently held a training day (both theory and fieldwork) in chalk logging; one of the modules that form part of the graduate training scheme.
This session focused on the White Chalk Subgroup, which is a major geological unit in the South East. The session comprised a morning theory running through the composition and structure of the chalk, together with logging training and identifying the main engineering considerations when carrying out site investigations on sites underlain by chalk. Topics included spread and piled foundations, solution features and deneholes. In the afternoon the graduates were taken to chalk exposures on the south coast at Newhaven (where the photos were taken) and Saltdean to study the chalk in situ and look at dry valley cross sections.
