Origins of Igneous Layering

Part of the book series: NATO ASI Series ((ASIC,volume 196))

Abstract

This glossary presents definitions for the terms that are most commonly used in the description of layered igneous rocks, and where necessary, examples are cited. The definitions are taken largely from a review by Irvine (1982), but they strongly reflect original treatments by Wager, Brown and Wadsworth (1960), Wager and Brown (1968), and Jackson (1967,1970), and later comments by Wadsworth (1985). A point to remember in applying the terms is that the difference between “layers” and “layering” is essentially a difference between individuals and a population; thus the words that describe one may not be appropriate to the description of the other. For examples, words such as “intermittent”, “graded”, and “isomodal” rigorously apply only to layers, whereas “rhythmic” and “modal” should be only applied to layering.
