Abstract

Statistical analysis of heat flow distribution along nine geotraverses crossing mid-oceanic ridges in the Atlantic, Pacific, and Indian oceans is carried out. Significant asymmetry of heat flow distribution is established: its mean values differ on opposite sides of ridge axes. In geotraverses of the Southern Hemisphere, their western flanks have a higher average heat flow, and on geotraverses of the Northern Hemisphere, the same is true of the eastern flank. Various tectonic factors leading to such a distribution are taken into account, but it is suggested that the universal cause of this regularity is the Coriolis effect, which, as the planet rotates, redistributes the amount of magmatic material in the asthenospheric reservoir.

世界海洋中洋脊热流不对称的性质

摘要

对横跨大西洋，太平洋和印度洋的中洋脊的九条地线的热流分布进行了统计分析。建立了显着的热流分布不对称性：其平均值在山脊轴线的相对两侧均不同。在南半球的地线中，它们的西侧具有较高的平均热流，而在北半球的地线中，东部侧也是如此。考虑到导致这种分布的各种构造因素，但建议这种规律性的普遍原因是科里奥利效应，当行星旋转时，它在软流圈储层中重新分配了岩浆物质的数量。
