<b><u>Presented as part of the Geological Society of America (GSA) Distinguished Lecturer Tour 2017</u></b><br><br><b>Hot Rocks Under Our Feet; Seismic Imaging of Igneous Geology in Sedimentary Basins</b><br><br>Volcanoes are hot, loud and scary, thus we know little of their internal structure or underlying 'plumbing systems', which typically comprise a complex network of dykes and sills. Magma intrusion in the Earth's crust, and the extrusion of this material on its surface, represent a natural hazard; however, these processes can also result in the formation of economic quantities of hydrocarbons. In this talk I will show how 3D seismic reflection data can illuminate the structure and emplacement mechanics of these 'hot rocks'. I will also demonstrate the key role igneous processes and products play in the development of petroleum systems on continental margins.
