A reconstruction of Holocene climatic changes from peat bogs in north‐west Scotland
Continuous palaeoenvironmental sequences from three peat bogs located in north‐west Scotland are presented which reveal palaeoclimatic changes during the Holocene, Peat cores were analysed lor humification. pollen and a range of other physical and palaeoecological data, and chronologies were constru...
