 Ritland, R. --- Historical Development of the Current Understanding of the Geologic Column: Part I
In 1756 Johann Gottlob Lehmann, a mining engineer and teacher in Berlin who investigated the rocks of Prussia, published a wealth of careful observations together with his ideas on the origin and composition of the earth's crust (Adams 1938:374-478; Zittel 1901:35).
Lehmann gave accurate descriptions, with sections and diagrams, of thirty successive "bands" in the Permian rocks of Thuringia.
Nearly all of the rocks — igneous (1), metamorphic and most sedimentary — he believed to be chemical or mechanical precipitates deposited during successive epochs from a primeval turbid ocean which enveloped the entire earth.

Just as a book can be called the fundamental unit of a library, so can rock formations be thought of as the fundamental units of historical geology.
