Forensics and Science

Soil micromorphology is the analysis of soil stratigraphy at microscopic level.

This provides information the soil formation processes, accumulation rates and what it consists of.  It also reveals evidence of re-working, highlighting the function and use of space over time.  Excavations below York Minster for the installation of a lift shaft provided the opportunity to obtain micromorphology samples to study sediment accumulation relating to Roman occupation, well before the Minster was constructed.  The slides revealed four rapid phases of demolition and sediment accumulation over a short period.  Demolition layers included oak charcoal, limestone and tile fragments relating to the clearance of Roman occupation.
