【摘要】 地压梯度(the pressure gradient in the lithosphere)是岩石圈中的一个极为重要的参数,直接影响着各种地质作用的解释。与地温梯度一样,岩石圈中的地压梯度在空间和时间上也应是复杂多变的。本文从理论方面论述,岩石圈中的地压梯度是非线性的,静岩压力梯度(the lithostatic gradient——the pressure resulting from the weight of the overburden)是岩石圈中地压梯度的最小值,受地温梯度的影响岩石圈中地压梯度明显增加,可达到静岩压力梯度的2倍以上。更多还原

【Abstract】 the pressure gradient of the lithosphere is a key to explain various geological processes, and it varies in time and sphere as similar as geothermal gradient. The paper has discussed the pressure gradient of lithosphere form the theory and indicated that the pressure gradient in the lithosphere is no-linear, and its minimum is the hydrostatic pressure gradient, and that the pressure gradient of the lithosphere will increase obviously from the contribution of both geothermal and weight of rocks, can be more than twice times as the hydrostatic pressure gradient.更多还原
