Brunswick Magnetic Anomaly Shows There's A Bit Of Africa In North America

The repeated cycles of plate tectonics throughout history that led to collision, assembly and disruption of large supercontinents have produced modern continents that are collages of bits and pieces of each other. Figuring out the origin and make-up of continental crust formed and modified by these tectonic events is a vital to understanding Earth's geology and is important for many applied fields, such as oil, gas, and gold exploration. In many cases, the rocks involved in these collision and pull-apart episodes are still buried deep beneath the Earth's surface, so geologists must use geophysical measurements to study these features.  read more
