J.R.L. AllenEmeritus Professor John Allen (1932-2020) was a British geologist who made substantial contributions to archaeology. He took a degree in Geology at the University of Sheffield and for many years taught Geology at the University of Reading, where his hief interests were in the sedimentology of fluvial deposits (especially the Devonian Old Red Sandstone) and in sedimentary processes and structures. In the 1980s he turned his attention to modern estuarine sediments, and became increasingly interested in the archaeology of British coastal environments, especially those of the Severn and other estuaries, where he showed in collaboration with professional archaeologists that an appreciation of geological processes is essential to an understanding of the archaeological sites and their landscapes. His contributions to postgraduate courses in Geoarchaeology at Reading stress the importance of an understanding of geological principles, maps, and materials, especially rocks and minerals, to the refinement and resolution of numerous archaeological problems.
