This page provides the fundamental strata sequences that are followed in each excavation unit. These sequences are correlated to the area frame (currently AAC, JPD), which are in turn based on the Mozan sitewide frame (currently MZA).
| Overall Mozan frame | MZA | March 2009 |
| Area sequences | AAA | (missing) |
| AAB | March 2001 | |
| AAC | September 2001 | |
| AAC phases overview | July 2001 | |
| AAD | MDOG 2001 | |
| AAD compared to C2 | July 2002 | |
| AAE early | July 2005 | |
| AAE late | July 2005 | |
| AAF | (missing) | |
| AAG (only for A14 features) | June 2007 | |
| JPA | August 2007 | |
| JPB | July 2008 | |
| JPD | October 2011 |
| Unit sequences | J2A | December 2010 |
