Stratigraphy 3
Stratigraphy 3 :
A branch of geology with the objective of reconstructing the order in which rocks in the earth's crust formed over time, to trace back to the evolution of individual sectors of surface, arriving at the geological history of the whole planet. Reconstruction of the stratigraphic succession respects several fundamental principles: The principle of superposition that provides the chronological order of the events that led to the formation of the series; - recognition of the aspects that define the various environments of rock formation; - recognition of gaps and discordances that highlight tectonic and sedimentary phenomena which have affected the sequence
