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

dataset: TCRAOTWTWT
Otway Basin Top Crayfish Two Way Time Structure Map using sun shading. Sun angle 80, azimuth 35 and vertical exaggeration 10. Pixel colours indicate red shallow (114ms), purple deep (3628ms) This structure map is a composite grid based on mapping done by Minerals and Petroleum Victoria, Primary Industries and Resources South Australia, Origin Energy and Cooper (1995b). The main features to note in this image are: 1) the southwesterly regional dip of the Top Crayfish Subgroup surface in the western and central parts of the basin relative to the eastern part where it dips towards the south, and 2) the absence of Crayfish Subgroup sediments on some of the basement highs in the western and central parts of the basin (e.g. Beachport, Hatherleigh, Kalangadoo, Lake Condah, Branxholme). This image is extracted from Petroleum Atlas of Victoria Figure C22 (November 2001) The entire report may be downloaded ( at no cost ) from https://gsv.vic.gov.au/searchAssistant/document.php?q=parent_id:43977
