Anatomical changes in rings of buried saltcedar stems

Anatomical changes in rings of buried stems can be used to date stratigraphy.

Detailed Description

Anatomical changes in rings of buried stems can be used to date stratigraphy. Saltcedar stem cross-section cut 2.8 m below the ground surface.  Following initial burial of 68 cm in 1969, ring-width decreased, vessel size increased, and annual transitions became less distinct. After a second burial by 41 cm in 1972, annual transitions became indistinguishable. (Friedman and others 2005, 2015).
