Summary:

Name abandoned. Name was applied to a 1.5 m thick carbonaceous shale in the Chinle Formation. Rocks formerly called Ciniza are within the newly named Bluewater Creek Member of Chinle in this report. The shale is so thin and of such limited extent areally--250 m x 550 m southeast of Fort Wingate, McKinley Co, NM--that a separate name for it seems of little use.
