Geoarchaeology is a major branch of archaeological science at the interfaces between geology, geography and archaeology, involving the combined study of archaeological, soil and geomorphological records and the recognition of how natural, climatic and human-induced processes alter landscapes. The formation and modification of past soils, and occupation sequences can be examined primarily through the use of soil micromorphological techniques and various physical and geo-chemical techniques. This short text aims to explain some of the basics of geoarchaeological approaches and research design used to tackle the investigation of landscapes and settlement archaeology, and the application of soil micromorphology to archaeological situations. The intention is to present a basic handbook of good practice, with case studies and examples, that any archaeologist or aspiring geoarchaeologist can use.
