- Abstract
A hypothesis is proposed that assumes magma superflows (MSF) propagating along interfaces between crustal layers from sources like major mantle plumes. The MSF projections onto the Earth's surface have clear relief expression both in oceanic and continental crust areas. At present, all such linear and arcuate positive relief forms are explained by appealing to 'plate tectonics,' which is not always a logical procedure. In many cases the MSF hypothesis removes these drawbacks and gives a more consistent and objective explanation of the observations. Recent data obtained by geological, geophysical, and remote sensing techniques provide description of MSFs 1000-1200 km long in the Komandorsky and Aleutian deep-sea basins of the Bering Sea. They originated and moved during Cenozoic time, the oldest probably in the early Oligocene and the youngest in the Pleistocene.
