...RICHARD J. STEWART Abstract The Aleutian abyssal plain is a fossil abyssal plain of Paleogene age in the western Gulf of Alaska. The plain is a large, southward-thinning turbidite apron now cut off from sediment sources by the Aleutian Trench. Turbidite sedimentation ceased about 30 m.y. ago...

... the contribution of ecologic factors to reef structure and growth. Second, it will examine some interpretations of reef paleoecology and, in the light of these, consider how fossil reefs can be recognized. This approach is justified on the grounds that, by the use of the term “reef,” one is making a comparison...

The Fourier method resolves a complex zooecial shape into multiple shape components (harmonics), which can be treated as individual...
