- Description
- investigators and a large team of graduate and undergraduate students are collecting seismic data that can be used to image structures in the crust to understand these tectonic events. Hundreds of geophones are being deployed along two ~300-km-long profiles across the suture and the basin, which record sound waves generated by a series of explosive charges spaced ~20 km apart. Geophones are also being deployed in a box focused on the basin to record explosive charges arranged in a grid. The investigators are using travel-time tomography to create velocity models that reveal the distribution of igneous rocks, variations in the thickness of the crust and variations in crustal composition. Besides a better understanding of fundamental tectonic processes, other benefits of this program include training and education of students, and characterization of basins and igneous rocks that might be good targets for carbon sequestration.
