| *Location* \\ | Entenlochklamm, Chiemgau Alps, Germany/Austria |
| *Depositional facies* \\ | Mountain stream, gorge; highly variable flow conditions and short transport |
| *Provenance* \\ | Orogenic; sediments and metasediments of the eastern alps (Kössener Becken/Schichten) |
| *Composition* \\ | SRFs (partly low grade metamorphic overprinted) → clay shales/shists (phyllite), limestones (packstones with fragments of fossiles), dolomite, marl, chert; PRFs (also low grade metamorphic overprinted) → monocrystalline quartz, plagioclase, hornblende, chlorite |

h6. Comments:

Die Entenlochklamm wird von der Tiroler Ache durchflossen, die den „Kaiserwinkel" im nördlichen Vorland des Kaisergebirges (genauer des Zahmen Kaisers) entwässert. Dort stehen deformierte und leicht metamorphisierte klastisch-karbonatische Gesteine der triassischen Kössener Schichten an.   Probenpunkt an einer schmalen, hochgelegenen, ca. 50 m langen Sandbank am stromabwärtigen Ende der Klamm.
