Abstract
Magnetic analyses have been carried out on sediments collected from Lough Catherine. Northern Ireland, as part of a wider environmental study. The sediments span the whole of the Holocene. Radiocarbon and pollen dating of the palaeomagnetic signature locked in the sediments form the basis of an Irish Holocene geomagnetic master curve. The mineral magnetic characteristics of the sediments correspond with environmental changes, such as eighteenth century landscaping and the elm decline as revealed by pollen analyses. Both marginal and central sediments have been analysed. The sediments can be correlated by using either magnetic, pollen, or 14C measurements. These three independent core correlation methods all agree extremely well with each other. A mathematical method is described which can be used to calculate continuous accumulation rates and influxes.
