Cemeteries not only provide a peaceful place to commemorate the dead, and observe and enjoy nature; they are also wonderful repositories for the study of local history and art. But that’s not all. Cemeteries also offer an easy introduction to science that anyone can enjoy.
A visit to a cemetery presents a wonderful way to learn about geology and the other sciences, such as chemistry, physics and engineering, that underpin it. For geologists – whether amateur, student or professional – almost any urban cemetery provides a valuable opportunity to carry out scientific fieldwork at leisure, right on the doorstep, and at no cost.
Geology on show
Because gravestones are made from a wide variety of rock types formed in a range of geological settings, cemeteries can be geological treasure-troves. Many headstones are made of polished stone, so reveal details – such as minerals and crystal features – that are not easy to see elsewhere. Some demonstrate the textures and mineral composition of igneous rocks – rocks formed when molten magma cooled and solidified. Others are happy hunting grounds for lovers of fossils. Some gravestones reveal sedimentary structures that show how the rock was originally deposited. Others provide clues to earth movements and environments that occurred hundreds of millions of years ago.
For those interested in engineering, examination of gravestones can also provide useful information about topics ranging from weathering of stone to atmospheric chemistry, effects of pollution, stability and settling in soils and land drainage.
Cemeteries in Oxford include ancient churchyards, such as St Andrews Headington, as well as Victorian cemeteries like Holywell (pictured top) and St Sepulchres, and more modern burial grounds, such as Headington Municipal cemetery. Together they exhibit the main features and stone types that can be seen in cemeteries all around Britain.
In the short video below, filmed in the churchyard of St Mary and John in Oxford’s Cowley Road, Philip Powell and I introduce the basics and show you how to get started in exploring these geological gems.
