Seismic interpretation of sill complexes in sedimentary basins: implications for the sub-sill imaging problem

This is a supplement to the paper "Seismic interpretation of Sill-Complexes in Sedimentary Basins: Implications for the Sub-Sill Imaging Problem" by "Christian Haug Eide, Nick Schofield, Isabelle Lecomte, Simon J. Buckley and John A. Howell*published in the "Journal of the Geological Society", published in 2018.<br><br>DOI of peer-reviewed paper: https://doi.org/10.1144/jgs2017-096,DOI to publically available preprint: https://dx.doi.org/10.17605/OSF.IO/JFS9X<br><br>*If you use any of the files provided here, you should cite this paper.*<br><br>Description:The input model in this paper is provided here so that it can be used by anyone who would like a complex geological model to test numerical geophysical methods. It shows Jurassic siliciclastic rocks intruded by a mafic sill complex. It is particularly interesting because of the complex shape of the sill complex, and because of the strong difference in density and acoustic velocity between sedimentary rocks and intrusives.<br>Dimensions:The model is 21 198 m long and 414 m high. The resolution of the model is 3 m/pixel laterally, and 0.5 m vertically. <br>Contents: <br>A1: Input model to seismic modelling, presented in paper as Figure 5D. Extrapolated architectural model of the sill-bearing parts of the Hurry Inlet section. Each pixel is 3 m in horizontal extent and 0.5 m in vertical extent. The gray values correspont to the following facies associations (FA in Table 1): FA1 (igneous intrusions, 97), FA2 (homogeneous sandstone. 159), FA3 (Sandstone, 124), FA4 (Poorly cemented sandstone, 55), FA5 (Heterolithic, 130), FA6 (mudstone, 111), and FA7 (Organic rich mudstone, 0). <br>A2: Very high-resolution versions of panels on left side of Fig. 11, showing comments and synthetic seismograms overlain the outcrop model. <br>A3: Very high-resolution version of panels on right side of Fig. 11, showing A) outcrop; B) reflectivity model; C) synthetic seismogram generated with seismogram using a 40 Hz wavelet and 80° max dip; D) Synthetic seismogram generated with seismogram using a 20 Hz wavelet and 50° max dip; E) Synthetic seismogram generated with seismogram using a 15Hz wavelet and 30° max dip. F) Synthetic seismogram generated with seismogram using a 10 Hz wavelet and 30° max dip.
