Abstract
Slip sliding away: Enigma of large sandy blocks within a gas-bearing mass transport deposit, offshore northwestern Greenland
Highlights
Sediments deposited by gravitational and mass-wasting processes are commonplace in deep-water settings (Prior et al, 1984; Hampton et al, 1996; Butler and Turner, 2010)
This paper reports the discovery of a gas-charged submarine landslide mass transport deposit (MTD) covering 420 km2 (162 mi2) above the Melville Bay ridge (MBR) rift structure
This study provides an important analog for significant reservoir occurrence in large MTD blocks and provides constraints on the basin development and petroleum prospectivity of northeast Baffin Bay
Summary
Sediments deposited by gravitational and mass-wasting processes are commonplace in deep-water settings (Prior et al, 1984; Hampton et al, 1996; Butler and Turner, 2010). These processes can create seismic-scale deposits consisting of chaotic facies that can commonly host rotated and translated slide blocks within the matrix of the flow. These blocks commonly consist of meter- to kilometer-scale packages of undeformed strata that have remained coherent and intact throughout the sliding process (Huvenne et al, 2002; Weimer and Shipp, 2004; Jackson, 2011; Alves, 2015). The paper concludes by assessing reservoir connectivity and the potential for exploration and development
