Definition

Gonzalez R., Wetzel A. (1996) : Stratigraphy and paleogeography of the Hauptrogenstein and Klingnau Formations (middle Bajocian to late Bathonian), northern Switzerland Eclogae geol. Helv. 89/2, 695-720

p.708: The Upper Oolitic Series (synonyms: "Grande Oolite": Thurmann 1832; "Upper

Hauptrogenstein": e.g. Mühlberg 1900; Schmassmann 1945) are 5-7 m thick in the eastern and up to 30 m thick in the western Jura (Fig. 4, 5b). They consist of oolitic mud- to grainstones with fine-sand sized oolites, which are usually smaller than those found within the Lower Oolitic Series. The matrix can be micritic, especially in the western Jura.

Typical sedimentary structures are oblique stratifications, ranging from centimeter-thick

ripple laminae to large foresets with a thickness of several meters. The top of the Upper Oolitic Series is a platform-wide hardground.
