PAPERS
DECAN Geosolutions strongly believes in innovative science to solve hydrocarbon exploration problems, as seen in our geological and geophysical services. These also include more specialized seismic interpretation and mineralogical insight of volcanic basins, as evidenced in selected papers.
Delineating the Exmouth mantle plume (NW Australia) from denudation and magmatic addition estimates
Volcanic margins are a class of large igneous provinces (LIPs) characterized by rifting-derived basaltic magmatism. This is commonly attributed to extension-related lithospheric thinning, generating decompression melting.
Intrusive large igneous provinces below sedimentary basins: An example from the Exmouth Plateau (NW Australia)
Large igneous provinces (LIPs) are commonly characterized by extrusion of huge outpourings of flood basalts. However, some LIPs associated with thick sedimentary basins display mainly intrusive sill and dike complexes and a relative absence of extrusives as
evidenced on the Exmouth Plateau.
Prospectivity of volcanic basins: Trap delineation and acreage de-risking
Prospect delineation in volcanic basins is commonly hampered by poor sub-basalt imaging. Recent seismic advances focusing on low frequencies have significantly enhanced structural imaging, but not the seismic resolution. Currently, the sub-basalt play is mainly a structural play. On the North Atlantic margin, success has been booked with the discovery of the sub-basalt anticlinal Corrib gas field, offshore Ireland.
Methodology for Evaluating the North Atlantic Igneous Province Reveals Multiple Hotspots at Breakup
The North Atlantic Igneous Province (NAIP) is a well-studied, but little understood Large Igneous Province, initiated ∼55–60 MY ago, characterized by flood basalt magmatism at high rates, not witnessed in human history.
