Synclinal \Syn*cli"nal\, a. [Gr. ? to incline together; sy`n
with + ? to incline.]
1. Inclined downward from opposite directions, so as to meet
in a common point or line.
2. (Geol.) Formed by strata dipping toward a common line or
plane; as, a synclinal trough or valley; a synclinal fold;
-- opposed to anticlinal.
Note: A downward flexure in the case of folded rocks makes a
synclinal axis, and the alternating upward flexure an
anticlinal axis.
