Deposition: introduction

Giorgio Buccellati – September 2010

The basic concepts are explained within the section on Principles of stratigraphic analysis. It must be stressed that I seek to keep a rigorous distinction between deposition on the one hand, and emplacement and typology on the other.

Essentially, deposition deals with the way in which things have come to be where they are now, through a number of possible processes (construction, accretion, discard, disaggregation). This section deals with each of these processes in turn, highlighting specific examples of each within the book in question.

As a result of depositinoal analysis, we can infer the sequence of phases and the strata into which the material fits.

A fuller typological description is given under typology.
