If the formation of traumatic resin canals in your specimens was caused by human activity, a practice which I observed 50 years ago carried on by mayan speaking people in the highlands of the state of Chiapas, Mexico, might offer a clue for the interpretation of your material. Intact, growing, native pines were wounded near the base with axes, later the freshly exposed wood was burned. Afterward, the burned area was scraped clean and the underlying resin-rich wood was split out of the trunk and used for torches.

Subject: Cedrus traumatic resin canals
In a lot of the Cedrus charcoal remains from different samples from a
Bronze Age site in Syria (Qatna) I found traumatic resin canals. Does
anybody know any good literature or information on the causes of
traumatic resin canals, especially for Cedrus?
Thank you very much in advance,
