Extensions of luminescence dating to other fired materials such as burnt flint, and to stalagmitic calcite and unburnt sediment are then outlined, including optical dating of the latter.
Final sections deal with limitations in age range, accuracy and error limits.
His best-known book, Science-based Dating in Archaeology (1990), became the standard undergraduate text on the subject.
