The Middle Jurassic is the middle geochronologic subepoch of the Jurassic, starting with the Aalenian age (at the transition from the Early Jurassic subepoch) and ending with the Callovian age (at the transition to the Late Jurassic subepoch). It is subdivided in four ages (Aalenian, Bajocian, Bathonian and Callovian).

The Early Jurassic is the first geochronologic subepoch of the Jurassic, starting with the Hettangian age (at the transition from the Late Triassic subepoch) and ending with the Toarcian age (at the transition to the Middle Jurassic subepoch). It is subdivided in four ages (Hettangian, Sinemurian, Pliensbachian and Toarcian).

The Middle Triassic is the middle geochronologic subepoch of the Triassic, starting with the Anisian age (at the transition from the Early Triassic subepoch) and ending with the Ladinian age (at the transition to the Late Triassic subepoch). It is officially subdivided in two ages (Anisian and Ladinian).
The Late Triassic is the last geochronologic subepoch of the Triassic, starting with the Carnian age (at the transition from the Middle Triassic subepoch) and ending with the Rhaetian age (at the transition to the Early Jurassic subepoch). It is subdivided in three ages (Carnian, Norian and Rhaetian).
The Lepontic tectonic domain is situated between the Helvetic and Penninic units in the internal part of the Central Alps. It is characterized by the presence of a structural and metamorphic dome (Lepontine Dome). Most of these units are derived from the most distal part of the thinned European margin.

In Western Switzerland, the internal part of the Lower Penninic subdomain is only represented by the Sion-Courmayeur Nappe, which extends along the entire front of the Penninic domain. Paleogeographically it corresponds to the oceanic Valaisan Basin, which was then incorporated in the subduction zone below the Middle Penninic units.

The Schangnau Slice is the second outermost tectonic unit of the Subalpine Molasse, situated between Steffisburg Slice, resp. the Marbach-Berneck Triangle Zone (below, to the north) and the Blueme-Beichle Slice (above, to the south). It consists exclusively of Lower Freshwater Molasse (USM) with characteristic «granitic sandstone».

The Stockhorn Nappe is a small tectonic unit of the Middle Penninic, located on top of the Monte Rosa Nappe and separated from the Zermatt - Saas Fee Nappe by the thin Gornergrat Nappe. It is lithologically similar to the Portjengrat Nappe and can thus be correlated with it.
The Quaternary is the last geochronologic period of the Cenozoic, starting with the Gelasian age (at the transition from the Neogene period) and still going on into the Present. It is subdivided in two epochs (Pleistocene and Holocene). The base of the Quaternary is set at the Gauss/Matuyama palaeomagnetic reversal and the period is characterised by successive glacials in a context of increased global ice volume. In Switzerland one can assume that all of the (peri)glacial deposits belong to the Quaternary.
