• Offshore-transition deposits consist of regularly interbedded, yellowish green and grey, parallel-laminated mudstone, and thin to thick, light grey, erosive-based, fine- to very fine-grained sandstone with hummocky cross-stratification, combined-flow ripple cross-lamination and ⁄ or symmetrical to near-symmetrical ripples at the top. Sandstone beds are usually laterally extensive, although displaying thickness variation. Hummocky cross-stratification is the dominant structure in the thickest sandstone beds, while combined-flow ripple cross-lamination tends to dominate in the thinnest beds. In contrast to lower-shoreface deposits, amalgamation of hummocky beds is uncommon. Common shell lags and intraclast layers are present at the base of hummocky beds. Gutter casts, load casts, tool marks and wrinkle marks are common. These deposits reflect alternation of quiet-water sediment fall-out, and combined and pure oscillatory flows due to frequent storms (Buatois & Mangano 2003; Buatois et al. 2006). The presence of thin mudstone intervals separating hummocky beds indicates periods of low energy between storm flows and deposition immediately below fair-weather wave base.
