| 摘 要： | 延用至今的地质作用深度测算方法，即重力／密度法，是基于“地下岩石处于静水压力状态”（Ｈｅｉｎ，１９７８）和“地下某一深处的垂直压力等于上覆岩石柱的总重量”（ДИＨＨИК，１９３７）两个理论假设。下面刊登的是“地壳异常压力学术研讨会”专家 必言（北京，２０００．２）。到会专家对上述假设和汕算方法提出了不同见解，指出，浅部地壳直到地幔深处的岩石都是固体状态，地下的压力是极不均匀的，所以对地壳中的地质作 |

| Abstract: | Papers collected in this volume are focusing on anomalous pressures present in the crust. Some theoretical considerations and calculations of pressures at certain depths are proposed. The pressure-depth relation can generally be obtained from a certain density-depth distributaion in the region. It is known from stress measurements that the horizontal stress is almost always great than the vertical stress. This indicates that tectonic stress may play some important role in the stress state. Furthermore,some other additional stresses may also be generated by facies changes,metamorphism,crystallization in the crust. How the UHPM rocks now exposed at the surface were formed is open to discussion. Lu et at (1988) proposed a method for determination of pressure at some depth. |
