IGCP Project 559 - Seismic Images

Sedimentary basins and continental rift/spreading zones

DEKORP 9 Transect, Germany
Transect crosses the Upper Rhine Graben, and obliquely intersects both the Saxothuringian and Moldanubian regions. These regions are separated by the SW-NE striking Lalaye-Lubine-Baden Baden shear zone. The Rhine Graben is a currently-active rift system.

BASIN '96 Transect, North Germany
Transect crosses the NE German Basin, a region that extends from the Palaeozoic Tornquist Suture Zone to the Harz Mountains, and from the North Sea to Poland. The basin shows a complex image reflecting different tectonic regimes and fault systems.

GLIMPSE Transect, Great Lakes region, Canada/USA
The transects cross the Great Lakes between Canada and the USA. GLIMPCE (Great Lakes International Multidisciplinary Program on Crustal Evolution) transects cross the Keweenawan Rift System (Lake Superior), an arcuate structure extending 2000 km from Kansas to central Michigan, with up to 25 km of syn-rift volcanics and interlayered sediments plus an additional 10 km of post-rift sediments. In Lake Huron, a transect crosses the Grenville Front Tectonic Zone, the northwestern edge of the Grenville Orogenic belt

Western Canada Sedimentary Basin Transect, Alberta, Canada
Transect crosses the Alberta basement of western Canada. The transect shows two layers, the lower, Precambrian crystalline basement of the Canadian Shield and the upper, an overlying veneer of sedimentary strata that constitutes the pertroleum-rich Western Canada Sedimentary Basin (WCSB).
