Abstract

The paper aims to investigate the geological structure of the Gulf of Saros and Gelibolu peninsula by using airborne magnetic data. To this end, derivative methods such as the second vertical derivative and tilt method have been applied to these data and created the anomaly maps. By a closer look at these maps, it is observed that there is an intense linear magnetic anomaly parallel to the shoreline of the Çanakkale Strait. This intense anomaly can be correlated with the Ganos Strike-slip Fault observed in the north-western part of the active tectonic map of Türkiye. In addition, the depth estimations utilizing the half-width method for simple geometric bodies suggest a deep source in the southwestern profile and a shallow source in the northeastern profile. As a result, it can be deduced that the magmatic material arising from the magma fills inside the strike-slip fault causing this magnetic anomaly. Such sources with deep roots could be prospective for geothermal energy as well as hydrocarbon maturation.

利用航空磁资料研究沙罗斯湾和格里波卢半岛的地质构造
利用航空磁资料对沙罗斯湾和格里波卢半岛的地质构造进行了研究。为此,利用二次垂直导数法和倾斜法等导数方法对这些数据进行了处理,绘制了异常图。通过仔细观察这些地图,可以观察到有一个强烈的线性磁异常平行于Çanakkale海峡的海岸线。这一强烈异常与在 rkiye活动构造图的西北部观测到的加诺斯走滑断层有关。此外,利用半宽度法对简单几何体进行深度估计,表明西南剖面为深源,东北剖面为浅源。因此,可以推断,岩浆产生的岩浆物质填充在走滑断层内部,造成了这种磁异常。这些深根源具有开发地热能和油气成熟的潜力。

期刊介绍: The journal publishes original research papers in the field of geodesy and geophysics under headings: aeronomy and space physics, electromagnetic studies, geodesy and gravimetry, geodynamics, geomathematics, rock physics, seismology, solid earth physics, history. Papers dealing with problems of the Carpathian region and its surroundings are preferred. Similarly, papers on topics traditionally covered by Hungarian geodesists and geophysicists (e.g. robust estimations, geoid, EM properties of the Earth’s crust, geomagnetic pulsations and seismological risk) are especially welcome.
