The other important thing to be determined and analyzed is the evolution of
the matrix over time.  Particular attention must be paid to the molecular
arrangement in the macro environment, and how that may have been altered
due to exterior environmental and societal influences.  Also important is
what is not there, and the proper assumptions necessary to assume that it
was once there.

Retrogressive analysis may be indicated if there can be demonstrated
shifting influences.  Gravitically-influenced locomotive processes are
likely to have resulted in altered states.  Stratification analysis may
yield missing mass, or better yet calcarous impressions of patterned
alterations.

Just do it.
