Otway Basin Top Basement Two Way Time Structure Map (1:1,000,000)

dataset: TBMTOTWTWT
Otway Basin Top Basement Two Way Time Structure Map using sun shading. Sun angle 80, azimuth 35 and vertical exaggeration 10. Pixel colours indicate red shallow (0ms), purple deep (4813ms) This structure map highlights the Late Jurassic - Early Cretaceous structure of the Otway Basin. The grid is based on mapping done by Minerals and Petroleum Victoria, Primary Industries and Resources South Australia, Origin Energy and Cooper (1995b). The main feature to note in this image is the variation in the orientation of the Late Jurassic - Early Cretaceous troughs and highs along the length of the basin. At the western and eastern ends of the basin, the troughs and highs are oriented both NE-SW and E-W (Robe Trough, St. Clair Trough, Rivoli Trough, Lake Eliza High, Beachport High, Elingamite Trough, Gellibrand Trough, Ombersely Trough, Nerita Deep, Snail Terrace). Those in the centre are oriented NW-SE (Penola Trough, Tantanoola Trough, Kalangadoo High, Hatherleigh High, Tahara Trough, Branxholme High, Ardonachie Trough, Lake Condah High). This variation in the orientation of the Late Jurassic - Early Cretaceous troughs and highs has resulted in considerable debate over the extension direction during this period. Some worker believe it was oriented NW-SE (Willcox & Stagg, 1990; Willcox et al., 1992; O'Brien et al., 1994), whereas others believe it was NNW-SSE (Cooper, 1995a,b; Cooper & Hill, 1997), N-S (Boeuf & Doust,1975; Ellenor, 1976; Hill et al., 1994a) or NNESSW (Etheridge et al., 1985, 1987; Smith, 1988).
