DECIPHERING THE ORDOVICIAN TECTONIC HISTORY OF A PORTION OF THE LIBERTY-ORRINGTON BELT IN SOUTH-CENTRAL MAINEContact relationships between the above units are obscured by poor exposure, extreme deformation and metamorphism. Geochemical analyses of metaigneous rocks in the study area are in progress ...
These findings are important for stratigraphy refinement and tectonic setting reconstructions, as well as oil and gas reservoir forecasts. 2. Geological Settings The Siljan Ring structure is located within the Trans-Scandinavian Magmatic Belt of the Baltic Shield. Magmatic rocks are represented mainly by...
Although you can’t actually see where the two tectonic plates of Europe and America meet, you can stand on the bridge. Better yet, you could go underneath the bridge and get a gorgeous view of the ocean. It’s hard to stand at this viewing platform and not feel mightyPhoto: Nicole K...
469–474 Ma and correlation with adjacent rocks of the more regionally extensive Casco Bay Group (CBG) in the Liberty–Orrington belt. New detrital zircon results from metasedimentary rocks in the EHG support this correlation; the age spectra indicate a peri-Gondwanan sedimentary source,...
