Having worked in almost all of the volcanic margins around the world, DougalEARTH brings experience from a variety of locations including: North Atlantic, South Atlantic (Parana-Etendeka/Karoo), Antarctica, India, Ethiopia, Siberia, China, USA/Canada and Australia. Additionally Dougal has published extensively leading the way with our understanding of volcanic facies in rifted margins and flood basalt provinces.
Key to understanding these provinces is looking at the volcanic fill, and associated intrusions, along with the sedimentary fill. Using this approach the temporal and spatial influence of the igneous rocks in the sedimentary basin can be fully realised and incorporated into facies architecture, case studies and 3D models.
- North Atlantic Igneous Province
- South Atlantic Margin; Namibia, Brazil
- Others; e.g. Columbia River, SE Asia, China
