Summary: A new interpretation of data suggests that the so-called oceanic crust in the area consists of Precambrian continental crust, partly Proterozoic orthoquartzite. Palaeogeographic evidence supports this, requiring large land masses as source areas for the sediments carried into the Japanese part of the Tethys. These conclusions require a fundamental revision of plate-tectonic models for the geological development of the island arcs and trenches in the NW Pacific region.
