Synonyms: -
Lithology: Black siliceous schists, alaun schists, lydites and rare intercalations of black limestones.
Fossils: Conodonts in limestone intercalations (FlaJS, 1964, 1967).
Origin, facies: Sapropelitic basinal sediments (Schön-laUb, 1982a).
Chronostratigraphic age: Silurian (Llandovery–Ludlow).

Lithostratigraphically higher rank unit: -
Lithostratigraphic subdivision: -
Underlying unit(s): Crinoidal Limestone, Lydites, Arkoses, Schists (SchönlaUb, 1982a).
Overlying unit(s): Cavernous Banded Limestone.
Lateral unit(s): Intercalations of Black Lydites, Alaun Schists with the Orthoceratid Limestone are named “Misch fazies” (SchönlaUb, 1992).
Geographic distribution: E-GWZ; Styria, Eisenerzer Alpen.
Remarks: The graptolites described by heritSch (1931 b) and haberFelner & heritSch (1932a) from the Black Lydites, Alaun Schists were recognized as anorganic re-mains (gräF, 1966).
Complementary references: tollmann (1977), Schön-laUb (1979, 1980a), ebner et al. (1989), SchönlaUb & heiniSch (1993).
