Blassenstein Formation (Blassenstein-Formation)
Validity: invalid; defined by Trauth
(1950: “ ..dichten, weißlich bis lichtgrauen und hellgelblichen, dünnbankigen .. Kalken und Mergelkalken“); later on used by
Decker (1987), and Schnabel (1999). Needs some revision and formalization.
Type area: UTM
map sheet 4328 Scheibbs, Lower
Austria (ÖK 50, map sheet 54

Type section: not formally defined.
Remarks: Fasselgraben Formation is used for largely similar strata of the Ybbsitz
Klippen Zone.

Validity: invalid; but accepted as an informal unit (Zementstein-Formation) by
the Swiss Stratigraphic Committee (Schweizerisches Komitee für Stratigraphie)
on 19th October 2006. The name was first used by A. Heim (1907), and revised by Mohr (1992). In Vorarlberg introduced
by A. Heim (1923).
Type area: Walensee area (Switzerland).
Type section: Lochezen near Walenstadt (fide
http://www.stratigraphie.ch/); approximately N 47° 7' 50'' / E 9° 16' 45''
(Swiss national coordinates: 740.000/221.600).
Reference section(s): see below.
Derivation of name: used for cement production.
Synonyms: Mergelschiefer; schieferiger Uebergangshorizont (Mylius, 1911); Zementsteinschichten (Felber & Wyssling, 1979).
Lithology: alternations of light-grey limestone (Typus
"Quintner Kalk"), and dark-brown strongly weathering shales (Felber & Wyssling, 1979).
Fossils: condensed bed with abundant ammonites forms the top of the Quinten
formation (Zittel, 1868; Vacek, 1879; Jeannet in Heim
et al., 1933; Oberhauser, 1951; Felber & Wyssling, 1979). An
additional ammonite bed was found immediately above the lower boundary of the
Zementstein Beds (Schaad, 1926; Felber & Wyssling, 1979). Further belemnites, brachiopods,
calpionellids (Felber & Wyssling,
1979); benthic foraminifera, echinoderms and ostracods (Colins et al., 1990).
Origin, facies: pelagic (Felber
& Wyssling, 1979).
Chronostratigraphic age: Tithonian to Berriasian.
Biostratigraphy: Lower boundary: uppermost Tithonian – Jacobi-zone
(ammonites - Felber & Wyssling,
1979).
Upper boundary: uppermost Lower Berriasian – below calpionellid zone
C (Felber & Wyssling, 1979).
Thickness: approximately 65 meters (Felber & Wyssling, 1979).

Lithostratigraphic subdivision: no subformation.
Underlying units: Quinten Formation.
Overlying units: the Palfris Formation develops gradually out of the
"Zementstein-Schichten". The boundary is defined by the last
intercalation of micritic limestone (Typus "Quinten-Kalk") (Wyssling, 1986).
Lateral units: no information available.
Geographic distribution: Vorarlberg: Bregenzerwald (Au – Kanisfluh) of ÖK 50,
sheet 112; UTM-sheet 1224.
Switzerland (Mohr & Funk, 1995).
Remarks (concerning the type area, type section and
reference sections): the
type section near Lochezen is tectonically truncated. The Swiss Stratigraphic
Committee suggests to chose a section described by Heim (1916) at Mount Alvier as new type section (fide
http://www.stratigraphie.ch/).

Waschberg Unit
G. Wessely
Ernstbrunn Limestone (Ernstbrunner Kalk)
Validity: invalid; the name (Boue, 1830) was used since 19th
century for Tithonian klippen within the outer Carpathian units (Hofmann, 2001); needs some revision and
formalization.
Type area: in northeastern Lower Austria (map sheet ÖK 24, Mistelbach; UTM-sheet 5308, 5314).
Type section: not
designated.
