Rock physics interpolation Used for velocity modeling of chalks: Ontong Java plateau example
Saberi, Mohammad Reza; Johansen, Tor Arne; Sælen, Gunnar (Peer reviewed; Journal article, 2010)Chalks are pelagic carbonate sediments that are deposited in deep-water environments. Their elastic behaviour is controlled by a combination of depositional conditions and subsequent diagenesis. In this paper, we incorporate ... -
Sequential growth of deformation bands in carbonate grainstones in the hangingwall of an active growth fault: Implications for deformation mechanisms in different tectonic regimes
Rotevatn, Atle; Thorsheim, Elin; Bastesen, Eivind; Fossmark, Heidi Synnøve Solli; Torabi, Anita; Sælen, Gunnar (Peer reviewed; Journal article, 2016-09)Deformation bands in porous sandstones have been extensively studied for four decades, whereas comparatively less is known about deformation bands in porous carbonate rocks, particularly in extensional settings. Here, we ... -
Sr/Ca in Calcitic Tests of Benthic Foraminifera - A Potential Water-Depth Proxy?
Sælen, Gunnar; Kristensen, Dorthe Klitgaard; Westerlund, Stig; Jansen, Eystein (Peer reviewed; Journal article, 2009)Well-preserved low-Mg calcite tests of modern benthic foraminifera from a depth transect off SW Norway show decreasing Sr/Ca with increasing water depth (r = –0.84). The Mg/Ca ratios also decrease with increasing water ...
