苏联科学院远东科学中心萨哈林科学研究所完成了120多个热流测量的成果,同时提出一份太平洋活动带西北部650个热流值的简图,其中包括其他机构的先前的成果。以前调查者们所确立的千岛—堪察加和日本群岛的热流分布总趋势,得到现今统计分析成果的支持。根据基于鄂霍茨克海区深地震测深剖面所得出的物质成分和放射性热源分布,估计了地壳和上地幔内的定温分布。按此成果,莫霍不连续面上的温度如下:鞑靼海峡下为800℃,千岛盆地下为500、600℃;千岛—堪察加海沟下为200℃。根据纵波和横波速度分布而计算出的500公里深度的上地幔内部分熔融的温度,与从上地幔电导率平均数据所估计的温度是很一致的。估算了地幔物质的粘度和瑞利数。
The Sakhalin Institute of Science at the Far Eastern Science Center at the Soviet Academy of Sciences completed the results of more than 120 heat flow measurements, along with a sketch of the 650 heat flow values in the Pacific Northwest, including previous results from other agencies. The overall trends in heat flux distribution in the Thousand Islands - Kamchatka and the Japanese archipelago established by previous investigators have been supported by the results of today’s statistical analysis. Based on the distribution of the material components and radioactive heat sources based on the deep seismic sounding profile in the Okhotsk Sea area, the distribution of the fixed temperature in the crust and the upper mantle was estimated. According to this result, the temperature on the Moho discontinuity is as follows: 800 ° C under the Tatar Strait, 500,600 ° C under the Thousand-Islet Basin; and 200 ° C under the Kuril-Kamchatka Trench. The partial melting temperature in the upper mantle, calculated from the longitudinal and shear wave velocity distributions at a depth of 500 km, is consistent with the estimated temperature from the upper mantle conductivity average. The viscosity and Rayleigh number of the mantle material are estimated.
