“…Work on conodonts by Glenister & Klapper (1966) and particularly by Seddon (1970) The precise age of the ramosa Zone remains unknown. We suggest it is late Givetian on the basis of its position between the Givetian fontanus Zone and the early Frasnian saltica Zone.…”

“…Because the reef complexes crop out for about 290 km along the northern margin of the shelf, and are also known from the subsurface, only a preliminary biostratigraphical correlation of the complex is available. Further difficulties in the way of the biostratigrapher, outlined by Seddon (1970), include the restriction of faunas to particular parts of the reef complex, and the apparent absence or paucity of conodonts and ammonoids from facies containing brachiopods. All three groups are useful for correlation.…”

“…This compilation does not include large quantities of unpublished data gathered by geologists of West Australian Petroleum Pty Ltd, the Bureau of Mineral Resources and the Geological Survey of Western Australia. Playford & Lowry (1966) simplified an existing stratigraphic terminology (Guppy et ah, 1958) and assigned, in general, one name to each of the reef, back reef, fore reef, and inter reef facies; locally however there are instances where two named units represent a single reefal element (Seddon, 1970), or where two reefal elements are referred to by a single name.…”

Analogue and Numerical Modelling of Sedimentary Systems: From Understanding to Prediction

Although factors that control the distribution of carbonate sediments are relatively well understood, their interaction in producing known geometries remains poorly known. A fine-scale forward model was developed to analyse the controls on decimetre-scale heterogeneity and carbonate facies distribution within larger-scale sediment bodies. The model was tested on a Frasnian (Late Devonian) patch reef, part of the so-called Glenister Knolls reef complex in the Canning Basin, Western Australia. The evolution of Glenister Knolls was digitally reconstructed using digital surveying technologies that resulted in a high-resolution dataset containing geological information from centimetrescale to outcrop dimensions. The three-dimensional digital outcrop model of Glenister Knolls was used to evaluate predictions from the fine-scale forward modelling results.The fine-scale forward model is based on a stochastic cellular automaton that simulates the spatial distribution of carbonate facies through time. The modelled carbonate facies is based on two main factors, stromatoporoid growth and sediment transport, and it successfully predicts the distribution of the basic elements -reef fabric and sediment -that compose the patch reef. The fine-scale forward model also successfully reproduces all major depositional relationships observed in the field such as backstepping, downlapping and interfingering contacts. The external structure of the reef is very sensitive to subsidence and production rates, since these directly influence accommodation space so constraining the vertical growth of the patch reef. However, the internal structure predicted by this model does not seem to be affected by one specific parameter, and displays the same sensitivity to other parameters, such as current intensity and wave amplitude.
