Title: Cycleology--A Discipline Concomitant to Paleoecology: ABSTRACT

Author(s): Maxim K. Elias

Article Type: Meeting abstract


The subject of cycleology is the detection and study of cyclicity in geological and paleontological phenomena, whereas paleoecology is concerned with the establishment and interpretation of ancient facies, and of the evidences of ancient life entombed in them.

Phase is the fundamental unit in cycleology, and recognition of a geological (or paleontological) cycle is based on the establishment of two or more successive orderly sequences of phases, be they lithological, paleontological, or a combination of both. Phase is analogous to paleoecological facies, but the two are not identical concepts. Part of a facies, or even all of it, may become a phase in a geological cycle.
