...Carlie Williams; Benjamin P. Flower; David W. Hastings Abstract The last deglaciation in the Northern Hemisphere was interrupted by two major stadials, the so-called “Mystery Interval” (17.5–14.5 ka) and the Younger Dryas (12.9–11.7 ka). During these events, the North Atlantic region was marked...

Macroseismic information is now available from 88 localities (more than tripling the current SHEEC data file); 75 of these are Portuguese, and the vast majority allow the assignment of an intensity value or interval (European Macroseismic Scale 1998 [EMS‐98]). These are supported by a total...

The main regolith horizons and distributions of selected elements at the Mystery Zone and background site are shown in Figures 4 and 5. Plotting intervals were selected on the basis of the principal...

... the Neoproterozoic–Cambrian interval’. Quantifying the palaeoerosion flux is difficult, however, and each method has its own caveats. Seawater 87 Sr/ 86 Sr, for example, is controlled by the age and type of materials undergoing weathering and thus only indirectly by erosion rates ( Berner & Rye 1992...
