predominantly, predominately

The huts are predominantly in valleys near rivers, and invariably the local area was swarming with mosquitoes—R. Sale et al., 1991

The music was predominately '60s and '70s pop, but that didn't seem to bother the inimitable Mr Hurst—Bookseller, 1993.

Both words mean 'as the most important factor or element, mostly, largely' and both have long histories, although predominately was rare before the 19th century and predominantly remains the more common of the two.
