在由长期冷凝及放射性元素衰变所产生的热中加入重力起源热,以减小赖以维持地幔对流的热能损耗与热能产量之间的差异。这种未被广泛认识到的热源来自于席状地幔柱从核幔边界附近上升时的粘滞摩擦,并引起地震、造山及火山活动。由于地幔柱中重馏分FeO 被地核顶部的熔融铁质所吸收,热柱中生成的摩擦热与重力势能的损失是相等的。将地幔物质放在用激光加热的金刚石压力计内,并施加以地下670 km 地震不连续面附近的温压条件,则它会转变为镁铁硅钙钛矿和镁方铁矿,而这些物质在核幔边界附近的温压环境下仍是稳定的,尽管地核吸收了它们中间的FeO。地球历史中由于这一过程所消耗的能量来源于外核中的Fe2O3,而这一物质成分是地震波速度和地球惯性矩所需要的。这一能量数值为707×1030 J,是板块以目前速率增长所消耗能量的23 倍。长期冷凝作用并不是起源于初始的高温,而是来源于放射性元素的衰变及地幔中FeO含量的减少。目前由地幔柱引起的板块增长提供了442 TW 总热能中的475% 。这些热能中的大部分来源于热柱的粘滞摩擦,其余部分则产生于地核的冷凝。放射性衰变提供了总热能的41% ,而没有板块增长参与的长期冷凝则提供了11% 的总热能。关于各?
Gravitational origin heat is added to the heat generated by long-term condensation and decay of radioactive elements to reduce the difference between the thermal energy loss and thermal energy yield that is dependent on maintaining mantle convection. This less widely known source of heat comes from the viscous friction of the mantle plume rising from near the mantle boundary and causing earthquakes, orogeny and volcanic activity. Since the heavy fraction FeO in the mantle plume is absorbed by the molten iron at the top of the core, the frictional heat generated in the hot column is equal to the loss of gravitational potential energy. The mantle material is placed in a laser-heated diamond gauge and applied to a temperature and pressure condition near the seismic discontinuity of 670 km below the ground, which transforms into magnesite-iron-perovskite and magnesian siderite, and these materials It is still stable under the temperature and pressure environment near the boundary of the mantle, although the core absorbs the FeO in the middle. The energy consumed by Earth's history as a result of this process is derived from Fe2O3 in the outer core, which is required for seismic velocity and Earth's moment of inertia. This energy value is 707 × 1030 J, which is 23 times of the energy consumed by the plate at the current rate. Long-term condensation does not originate from the initial high temperature, but from the decay of radioactive elements and the decrease of FeO content in the mantle. The plate growth currently caused by mantle plumes provides 47.5% of the total heat energy of 44.2 TW. Much of this heat comes from the viscous friction of the hot column and the rest from the condensation of the earth's core. Radioactive decay provides 41% of the total heat, while long-term condensation involving no plate growth provides 11% of the total heat. About each?
