The structures determined by the time-distance curves in the refraction studies were based on the assumption that there is no masked layer within the crust. They do not seem to conform well to either the results of the gravity analysis or surface wave studies. If the second layer, which has not been revealed by the refraction studies, is taken into account, the situation becomes much better. This fact leads us to suspect that, 1) there may be a layer of larger compressional wave velocity (6.6\uff5e6.7 km/sec) in the lower part of the crust, or there may be a velocity increase towards the base of the crust. 2) The mean crustal density and the vertical velocity distribution may not be very different from those of the standard continental crust. 3) An intermediate layer may exist just below the Moho discontinuity though the physical and geometrical structure of the layer remains uncertain. Adopting the crustal sections described above, the most probable depth of the Mohorovicic discontinuity in every 1\u00b0 square on land defined in Part 1 of this study has been determined from the reduced Bouguer anomalies.", "subitem_description_type": "Abstract"}, {"subitem_description":
