Research interests 

The underlying theme of my present research is to describe scientifically the technical expertise of ancient builders and architects. I apply analytical techniques from the earth sciences to the archaeological study of the cut-stone and concrete architecture of ancient Rome, which is unique in its innovative use of local volcanic rock and its continuation to modern time. 

Currently, I am integrating experimental tests of stone and concrete material properties, studies of Roman volcanic stratigraphy, and petrographic and geochemical investigations of diagenetic processes in Roman volcaniclastic rocks with field observations of ancient concretes in monumental structures and seawater harbor constructions.

Correlation of the results of these observations and laboratory tests with analyses of ancient texts (such as Vitruvius' De Architectura (31-27 BCE)) reveal the processes of human observation, discovery, and invention that led to the development of extraordinarily durable Roman concretes.

These multi-disciplinary methods will help solve archaeological, geological, and materials science research problems and assist in preservation of structures that are of archaeological and anthropological significance to academic researchers and the general public.

For information about the repository of samples of ancient Roman building stone and concrete, collected with the permission of the Soprintendenza Archeologica di Roma and the Sovraintendenza ai Beni Culturali del Comune di Roma, please send an email message with your query to Marie.Jackson@nau.edu.

Innovations in teaching that illustrate processes of earth and human history recorded by stone buildings in Flagstaff:     

  • Curricular materials - hands-on laboratory geoscience kits - for 9th grade geosciences programs in Flagstaff high schools.
  • Workshops for elementary school teachers through Willow Bend Environmental Resource Center, which illustrate active geologic processes within the city and ancient geologic processes that produced local building stone. These form part of 3rd grade social studies and science programs.
  • Lectures to diverse community groups on topics relating geosciences, civil engineering, and history in Flagstaff.
