热流值与海底扩张的一般关系热流值是从地球内部到地表温度能量的传导,在那里发生散失。温度随深度而增加的比率(地温梯度)是与岩石的导热系数有关,岩石的导热系数又是可以测量的。大洋和大陆有相同的平均热流值(约5微卡/厘米~2/秒)。从所测得热流值的资料,可看出远离洋脊而降低,海沟消减带附近也降低,但在岛弧后侧增高,裂谷带的热流值也高。鲁宾莫娃认为苏联的大陆区热流值的变化,是与一定的区域构造有关。李总结了三千个热流值的资料,认为前寒武纪地盾区热流值一般偏低,克拉通周围的褶皱带为中等热流
The general relationship between heat flow and submarine expansion Heat flow is the conduction of energy from the Earth’s interior to the surface temperature where it dissipates. The ratio of temperature to depth (geothermal gradient) is related to the thermal conductivity of the rock and the thermal conductivity of the rock is measurable. Ocean and continent have the same average heat flow value (about 5 micro-cal / cm ~ 2 / s). From the data of the measured heat flow, it can be seen that the distance from the oceanic ridge decreases, and the vicinity of the trenches decreases. However, the value of the heat flux in the rift zone is also high at the back of the island arc. Rubin Mauva that the changes in the value of the heat flow in the mainland of the Soviet Union, is related to a certain regional structure. Li summarized the data of 3,000 heat flow values and concluded that the Precambrian heat shield is generally low in heat flow and the fold zone around the craton is moderately heat
