Parschlug (Miocene of Austria)

Where: Steiermark, Austria (47.5° N, 15.3° E: paleocoordinates 47.0° N, 14.9° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Badenian (13.7 - 12.7 Ma)

• Considered to be late Karpatian to early Badenian (late Early to early Middle Miocene)

• group of beds-level stratigraphic resolution

Environment/lithology: pond; lithified lithology not reported

• In the Parschlug basin, sands and sandstones overlie the basement. A 4-8 m thick coal seam ("Parschlug seam") follows in the section. Towards the east and northwest the seam thickness decreases, and the seam splits up and wedges out. Therefore, mining activity was focussed formerly on the southwestern part of the depression. Clays and marls with up to 10 cm thick marlstone-ironstone intercalations (German: Toneisensteinbänke) overlie the seam. At certain levels they bear plant remains known as the famous flora of Parschlug (and presumably the insects). The ash content of the coal is relatively high (up to 40 %). The sulphur content of 4 to 7 % and the preservation of gastropod shells (Planorbis aplanatis) in an inter-seam indicate a relatively high pH-value (around 7) of the mire.

Size classes: macrofossils, mesofossils

Preservation: mold/impression, adpression
