and Bajocian coastal aquifer of the Caen area (northern France)," Applied Geochemistry, vol.
In fact, the paleontological content (Dieni et al., 1983; Dieni et al., 2013 and references therein; Scanu et al., 2014) does not have good enough stratigraphic detail to enable a minute subdivision into Bajocian and Bathonian
times (Del Rio, pers.
to Kimmeridgean) Fm is the basal Jurassic sandstone.
Based on the results of the study of the clay mineral assemblage in the Middle Jurassic sedimentary succession of the Kachchh Basin, India, the Bajocian to Middle Bathonian
time interval is interpreted to represent subtropical climatic conditions with seasonal droughts and a moderate supply of terrigenous clastics to the basin.
Evenchick and McNicoll (2001) also report well preserved late Bathonian
ammonites from the upper sedimentary succession about 2 km stratigraphically above the mafic volcanic rocks.
vertebralis from the Middle Bathonian
, Jurassic of Blumberg, SW Germany, and Pentaditrupa subtorquata from the Upper Campanian, Cretaceous of Hover by Hannover, Germany, were selected for SEM study.
As a Bathonian
, I took particular pleasure in unravelling Mozart's numerous if second-hand contacts with that city.
The depositional environment and sequence stratigraphy of the Samana Suk Formation (of Collovian- Bathonian
age) based on field and petrographic data is presented.
