A lithospheric drip is a geological phenomenon in which a dense and relatively cold mass of lithosphere sinks into the more fluid upper mantle. The regions of descending material have been detected by seismic tomography methods and modeled as near vertically oriented cylindrical masses within the upper mantle. The lithospheric drip discovered below the Great Basin in central Nevada has dimensions of 100 km diameter by 500 km vertical length.

  • 岩石圈滴落(英語:Lithospheric drip)指的是一塊緻密且較冷的岩石圈塊沉入流動性較強的上地幔中。岩石圈下降的區域已經由地震斷層掃描方法檢測到,經過建模為在上地幔內接近垂直方向的圓柱體。在內華達州中部大盆地下方發現的岩石圈滴落直徑為100公里,垂直長度為500公里。在內華達山脈西南部和加利福尼亞聖華金谷的部分地區,相對高密度的岩石圈滴落覆蓋100乘225公里的面積。在這裡,縱波速度快而且地形異常。 (zh)

  • A lithospheric drip is a geological phenomenon in which a dense and relatively cold mass of lithosphere sinks into the more fluid upper mantle. The regions of descending material have been detected by seismic tomography methods and modeled as near vertically oriented cylindrical masses within the upper mantle. The lithospheric drip discovered below the Great Basin in central Nevada has dimensions of 100 km diameter by 500 km vertical length. Another area underlain by a descending cylindrical mass of dense lithosphere has been reported in the southwestern Sierra Nevada and portions of the San Joaquin Valley of California. Here a 100 km by 225 km mass of relatively high density (fast p wave velocity) has been discovered below an area of anomalous topography. (en)
