compare and contrast the mineralogy, geochemistry and micropalaeontology of different marls seams within the Chalk in order to investigate the environment of deposition of different marl seams, and how they impacted the Cretaceous marine environment.
Description Paleoenvironmental development of marls seams in the UK Chalk Overview: The Upper Cretaceous of the UK and other areas of Northern Europe is dominated by the deposition of chalk – a micritic limestone composed of the shell fragments of calcareous algae (coccoliths). The deposition of the Chalk was interrupted by periods of enriched clay […]
