Scammet's Well, Willunga (Eocene of Australia)

Where: South Australia, Australia (35.3° S, 138.6° E: paleocoordinates 55.3° S, 133.6° E)

• coordinate based on nearby landmark

• outcrop-level geographic resolution

When: Blanche Point Formation, Priabonian (38.0 - 33.9 Ma)

• group of beds-level stratigraphic resolution

Environment/lithology: deep subtidal ramp; lithified marl

• The most parsimonious palaeoenvironmental interpretation of these mixed terrigenous-carbonate and biosiliceous sediments is a relatively quiet seafloor setting, below wave base, occasionally disrupted by storm waves, as postulated by Daily et al. (1976). There is no modern analogue to these sediments in offshore southern Australia except in deep waters (>200 m deep) on the upper continental slope (James et al., 1992, 1994, 1997; Boreen et al., 1993). Such water depths are unlikely for Blanche Point deposition, given the lateral gradation of these sediments into nearshore, low-gradient paralic to strandline siliciclastics.
