The Laboratory of Environmental Archaeology (LEA) is a multidisciplinary core facility dedicated to high-quality analytical services, equipment access, training, and laboratory support for academic, governmental, and industry users. Our specialty services include physical and geochemical characterization of archaeological and environmental materials and near-surface geophysical data collection. Specialized equipment includes our laser diffraction particle size analyzer, portable X-ray florescence spectrometer, and ground penetrating radar system. An APHIS inspected facility authorized to receive foreign and domestic soil, LEA can receive and analyze samples from around the world.

Housed within the university’s McClung Museum of Natural History & Culture, LEA provides a practical institutional mechanism for faculty collaboration, student experiential learning, and continuing education. LEA fulfills a unique role for researchers, students, and private companies by providing guidance and support to a variety of disciplines including archaeology, geoarchaeology, historical ecology, engineering, soil and agricultural sciences, environmental sciences, geology, geomorphology, and botany.
