MM 5.00, Mt. Mangart (Jurassic of Slovenia)

Where: Slovenia (46.4° N, 13.7° E: paleocoordinates 31.7° N, 22.0° E)

• coordinate stated in text

• small collection-level geographic resolution

When: Early/Lower Toarcian (183.0 - 182.0 Ma)

• early to middle? Toarcian; standart ammonite zones NW Europe: Tenuicostatum - Variabilis; zonation of Pessagno et al. (1987), NAmerica: subzone 01B - possibly subzone 1A2; Hori (1990), Japan: uppermost Trillus elkhornensis subzone of Parahsuum simplum (Ps) Assemblage zone; located in unit 3 of the local section

• bed-level stratigraphic resolution

Environment/lithology: basinal (siliceous); lithified, gray, cherty/siliceous packstone and lithified, gray, cherty/siliceous wackestone

• The studied succession was deposited on a south Tethyan rifted block, subsided to water depths of a few hundred meters. The depositional environment was oxygen depleted and characterized by high clastic input.The Jurassic succession of at least part of the Julian Alps, including Mt. Mangart, accumulated on a subsided block, directly attached to the northern margin of the Friuli (Dinaric) Carbonate Platform.

• black shale and dark gray, siliceous, laminated limestone (clearly of turbiditic origin); several milimeters thick laminae of packstone alternate with up to 1.5 cm thick beds and laminae of wackestone; limestones show parallel and cross-lamination, normal and inverse grading

Size class: microfossils

Collection methods: bulk, acetic, hydroflouric,
