Title: Stratigraphy and Correlation of Typical Blakeley and Blakeley Harbor Formations of Washington: ABSTRACT

This paper defines and restricts the lithologic character of the Blakeley Formation and records the lithologic and biologic mixing that has taken place during the deposition of this formation.

The uppermost part of Weaver's type Blakeley Formation was deposited in a nonmarine environment and is lithologically distinct from the underlying strata. It appears advisable, therefore, to restrict the Blakeley Formation to the marine-deposited strata and to rename the superjacent unit.
