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 ...
Geochronology, geochemistry, and tectonic setting of Ordovician metavolcanic rocks in the Liberty–Orrington belt, Maine: implications for the evolution of peri-Gondwanan arcs in the northern AppalachiansThe Yarmouth Island Formation of the East Harpswell Group (EHG) is an assemblage of metamorphosed...
Ring of Fire, long horseshoe-shaped seismically active belt of earthquake epicenters, volcanoes, and tectonic plate boundaries that fringes the Pacific basin. Most of the world’s earthquakes and approximately 75 percent of the world’s volcanoes occur w
