Stratigraphy Quotes (6 quotes)
As a graduate student at Columbia University, I remember the a priori derision of my distinguished stratigraphy professor toward a visiting Australian drifter ... Today my own students would dismiss with even more derision anyone who denied the evident truth of continental drifta prophetic madman is at least amusing; a superannuated fuddy-duddy is merely pitiful.
Changes, cyclic or otherwise, within the solar system or within our galaxy, would seem to be the easy and incontrovertible solution for everything that I have found remarkable in the stratigraphical record.
Geology got into the hands of the theoreticians who were conditioned by the social and political history of their day more than by observations in the field. We have allowed ourselves to be brainwashed into avoiding any interpretation of the past that involves extreme and what might be termed catastrophic processes. However, it seems to me that the stratigraphical record is full of examples of processes that are far from normal in the usual sense of the word. In particular we must conclude that sedimentation in the past has often been very rapid indeed and very spasmodic. This may be called the Phenomenon of the Catastrophic Nature of the Stratigraphic Record.
In the preface to his great History of Europe, H. A. L. Fisher wrote: Men wiser than and more learned than I have discerned in history a plot, a rhythm, a predetermined pattern. These harmonies are concealed from me. I can see only one emergency following upon another as wave follows upon wave It seems to me that the same is true of the much older [geological stratigraphical] history of Europe.
Let us make an arbitrary decision (by a show of hands if necessary) to define the base of every stratigraphical unit in a selected section. This may be called the Principle of the Golden Spike. Then stratigraphical nomenclature can be forgotten and we can get on with the real work of stratigraphy, which is correlation and interpretation.
Sedimentation in the past has often been very rapid indeed and very spasmodic. This may be called the Phenomenon of the Catastrophic Nature of the Stratigraphical Record.
