An orogenic event may be studied: (a) as a tectonic structural event, (b) as a geographical event, and (c) as a chronological event.
Phanerozoic (540 Ma to present) and Precambrian ( 4.6 Ga to 540 Ma ) had primarily passive margins and detrital zircons (and orogenic granites ), whereas the tenure of Pangaea contained few.
Granite often occurs as relatively small, less than 100 km² stock masses ( stocks ) and in batholiths that are often associated with orogenic mountain ranges.
Gustav Steinmann (1906) recognised different classes of orogenic belts, including the Alpine type orogenic belt, typified by a flysch and molasse geometry to the sediments; ophiolite sequences, tholeiitic basalts, and a nappe style fold structure.
However, interpretation of orogenic belts can be difficult.
Orogeny was used by Amanz Gressly (1840) and Jules Thurmann (1854) as orogenic in terms of the creation of mountain elevations, as the term mountain building was still used to describe the processes.
