| 1 | 均衡模型在莫霍面反演中的应用综述显示文摘莫霍面是重要的地质与地球物理界面,对其深度分布的研究是地球物理领域的重要内容.莫霍面深度分布与地球均衡重力场之间有重要关系,但长期以来部分研究人员在使用重测-均衡方法探究莫霍面深度时或多或少地忽视了参考均衡模型的重要性,造成了均衡补偿模式理论发展与重测-均衡方法研究莫霍面深度之间的不同步.本文介绍了世界上常用的几种均衡补偿模式当前的发展状况,对均衡解释中的一些争议问题和应用性问题进行了讨论,并针对莫霍面深度反演问题,指出了传统重测—均衡方法尚需进行的改进,并从五个方面阐释了均衡理论对传统反演方法的贡献,并探讨了下一步可继续探究的方向. | 邢健 郝天珧 徐亚 秦静欣 | 2014 | 地球物理学进展2014，29，1： | 6 |
| 2 | Crustal structure beneath Cameroon from EGM2008显示文摘We used the Earth Gravitational Model( EGM2008) data sets to analyze the regional gravity anomalies and to study the underground structures in Cameroon. We first created a high-resolution Free-Air anomaly database,then corrected the gravity field of the topographic effect by using ETOPO1 DEM with a resolution of0.01° to obtain the Bouguer anomaly,then applied a multi-scale wavelet-analysis technique to separate the gravity-field components into different parts of shallow-to-deep origins,and finally used the logarithmic power spectrum technique to obtain detailed images and corresponding source depths as well as certain lateral inhomogeneity of structure density. The anomalies of shallow origin show successive elongated gravity 'highs'and'lows'attributable to subsurface Tertiary and lower Cretaceous undulations. Our results are in good agreement with previous investigations. | Ngatchou Heutchi Evariste Liu Genyou Tabod Charles Tabod Kamguia Joseph Nguiya Severin Tiedeu Alain KE Xiaoping | 2014 | Geodesy and Geodynamics2014，5，1： | 2 |
