| Abstract |
Although common in occurrence in many basins in the world, the 3D seismic expression of volcanics is somewhat under-reported in the geological and geophysical literature. Although magnetic data can often identify volcanic rocks in the sedimentary column, pole-reversal with remnant magnetization, diagenetic alteration of volcanic extrusives, and shallow basement structures can all contribute to ambiguous magnetic signatures. Fortunately, both volcanic extrusive flows and intrusive dikes and sills often have a distinct seismic signature that once seen, are often easy to recognize. In order to build such a geomorphological catalogue, we present seismic amplitude and attribute images of both intrusive and extrusive volcanic seen in a modern 3D survey acquired over the Chicontepec Basin, Mexico. |
