Paleomagnetism, magnetic properties and thermal history of a thick transitional-polarity lava
The Roza flow of the Columbia River Basalt group in Washington State U.S.A. extruded at about 15 Ma during intermediate geomagnetic polarity. The Roza is underlain by normal polarity flows and overlain by reversed units. The Roza is an extensive flow, up to 60 in thick. As the remanence-blocking iso...
