Abstract
The Biga-Çan area in the NW Turkey is described with strike-slip and extensional features. The study area also contains features interpreted as the marks of the Intra-Pontide suture, consisting the boundary between the Sakarya Zone and the Strandja-Rhodope massifs.
In this study to extract more information about the area, 3D Euler deconvolution is applied on the gravity data collected by the Turkish Petroleum Co. (TPAO) with 1km inter-station spacing. The index parameter is selected as n=0 and n=1, corresponding to thin sheet edges and thin bed faults respectively. The selection of the index parameter and its meaning is usually ambiguous as in many studies fractional index parameters are used. Thus, 3D models are created using traditional smooth inversion and using a Global Optimization algorithm and the results of the 3D Euler deconvolution is compared to modeling results.
The results shows that a structural index parameter near n=0 marks the boundary between the sedimentary units and the crystalline basement. The agreement between 3D Euler deconvolution and 3D modeling results suggests that the 3D Euler deconvolution may be employed for mapping the approximate sedimentary thickness in the area.
