摘要为提高对利比亚西北部Tarhunah地区构造的认识，将遥感、地表地质和重力测量数据相结合。地质信息和遥感数据提供了有关地表结构的信息。为了破译地下构造，进行了重力测量。结果表明，宽度为39 ~ 48 km的盆地向东北方向发展。二维（2-D）模式显示盆地向西南方向逐渐加深。根据水平梯度、倾斜导数和欧拉反褶积确定的断层显示深度范围为2.5至7.5 km。综合和解释结果表明，火山活动与贾巴尔隆起背斜构造的构造活动有关。
Abstract The present work deals with the integration of remote-sensing, surface-geology and gravity-survey data to improve the structural knowledge of the Tarhunah area, northwest Libya. Geological information and remote-sensing data provided information about the surface structure. A gravity survey was conducted to decipher the subsurface structure. The results revealed that a basin having a width of 39 to 48 km trends NE. A two-dimensional (2-D) schematic model shows that the basin gradually deepens toward the southwest. Faults determined from a horizontal gradient, tilt derivative, and Euler deconvolution show a depth range of 2.5 to 7.5 km. The integration and interpretation of the results indicate that volcanic activity was related to the tectonic activity of an anticlinal structure called the Jabal Uplift.
