To investigate the crustal structure of the Archangelsky Ridge, gravity data obtained from the World Gravity Map (WGM2012) were analyzed using Total Horizontal Derivative (THD), Parker-Oldenburg (PO) inversion and Normalized Full Gradient (NFG) techniques. The THD method was applied to the Bouguer gravity after band-pass filtering in order to image the discontinuities. The maximum amplitude values ​​of the THD were used to reveal the discontinuities caused by the density difference in the Archangelsky Ridge and its vicinity. In addition, the basement upper surface topography of the region was calculated and mapped with the inverse solution. Moreover, the presence of an uplift area in the northeast of the study area, as well as the elevation of the Archangelsky Ridge was determined. The depth to the Cretaceous aged sedimentary basement in the Sinop basin and on the Archangelsky Ridge approximately reaches 4 km and 1.6 km, respectively. The average upper surface depth of the basement is calculated as 5 km under the Eastern Black Sea Basin (EBSB). Finally, depth calculations were made using NFG method for the selected profiles and correlated with gravity inversion results. The depth results of the basement upper surface topography obtained from NFG and inversion methods are compatible with each other within ± 0.1 km error limits.

为了研究 Archangelsky Ridge 的地壳结构，使用总水平导数 (THD)、Parker-Oldenburg (PO) 反演和归一化全梯度 (NFG) 技术分析了从世界重力图 (WGM2012) 获得的重力数据。在带通滤波之后将 THD 方法应用于布格重力，以对不连续性进行成像。THD 的最大幅度值用于揭示由 Archangelsky Ridge 及其附近的密度差异引起的不连续性。此外，还计算了该区域的基底上表面地形，并用逆解绘制了地图。此外，还确定了研究区东北部存在隆起区，以及 Archangelsky Ridge 的海拔。锡诺普盆地和阿尔汉格尔斯基海岭白垩纪时代沉积基底的深度分别约为 4 公里和 1.6 公里。基底的平均上表面深度计算为黑海东部盆地 (EBSB) 下 5 公里。最后，使用 NFG 方法对选定的剖面进行深度计算，并与重力反演结果相关联。NFG和反演方法获得的基底上表面地形深度结果在±0.1 km误差范围内相互兼容。使用 NFG 方法对选定的剖面进行深度计算，并与重力反演结果相关联。NFG和反演方法获得的基底上表面地形深度结果在±0.1 km误差范围内相互兼容。使用 NFG 方法对选定的剖面进行深度计算，并与重力反演结果相关联。NFG和反演方法获得的基底上表面地形深度结果在±0.1 km误差范围内相互兼容。
