sedimentary (adj.)

1760, "pertaining to or of the nature of dregs or sediment; precipitated by gravitation from a liquid;" see sediment + -ary. Sedimentary rock in geology is that formed by deposition of material previously suspended in water," attested by 1814.

Sedimental (adj.) "pertaining to dregs" is recorded from c. 1600 and might have lived long enough for a *sedimental journey pun but didn't.
