“…In Figure 5, obtaining of transition zone featured structures in a wide area from North of Bitlis Zagros Suture Zone to Black Sea is a trace about the grandness of effected area of the deformation. The positive amplitude anomalies in vertical derivative method indicate the location of the structure (Gönenç, 2014). Relatively, the reduction on derivative values corresponds to the transition zone between two structures.…”

“…The Curie depths and heat flow values were obtained by using aeromagnetic data by Pamukçu et al (2014). In the light of previous gravity and magnetic studies, in this study the estimation of the structure locations in Eastern Anatolia were done by applying the trend analysis, vertical and horizontal derivative methods (Butler, 1984;Gönenç, 2014) to the gravity data. In the last step, the results of this study were examining together with the results of the previous geophysical and geological studies.…”

“…The mappable targeting criteria for REE deposits in the study area were represented in the form of GIS layers or predictor maps for inputting into the FIS. The details of the primary data, the algorithms and GIS tools and techniques used to generate input predictor maps are provided in Tables 4A, B and C. (Gönenç, 2014) where the rift zone is at its maximum dimension. Upwards continued geophysical data shows the extension of the rift at depth.…”

Abstract. A two-stage fuzzy inference system (FIS) is applied to prospectivity modelling and exploration-target delineation for REE deposits associated with carbonatite-alkaline complexes in western part of the state of Rajasthan in India. The design of the FIS and selection of the input predictor map are guided by a generalised conceptual model of carbonatite-alkaline-complexes-related REE mineral systems. In the first stage, three FISs are constructed to map the fertility and favourable geodynamic settings, favourable lithospheric architecture, and favourable shallow crustal (near-surface) architecture, respectively, for REE deposits in the study area. In the second stage, the outputs of the above FISs are integrated to map the prospectivity of REE deposits in the study area. Stochastic and systemic uncertainties in the output prospectivity maps are estimated to facilitate decision making regarding the selection of exploration targets. The study led to identification of prospective targets in the Kamthai-Sarnu-Dandeli and Mundwara regions, where project-scale detailed ground exploration is recommended. Low-confidence targets were identified in the south of the Siwana ring complex, north and northeast of Sarnu-Dandeli, south of Barmer, and south of Mundwara. Detailed geochemical sampling and high-resolution magnetic and radiometric surveys are recommended in these areas to increase the level of confidence in the prospectivity of these targets before undertaking project-scale ground exploration. The prospectivity-analysis workflow presented in this paper can be applied to delineation of exploration targets in geodynamically similar regions globally such as Afar province (East Africa), Paraná-Etendeka (South America and Africa), Siberian (Russia), East European Craton-Kola (Eastern Europe), Central Iapetus (North America, Greenland and the Baltic region), and the Pan-superior province (North America).

“…On the geological map sheet, there are several structures of alleged fault indication in the form of a lineament in Tejakula. Knowing and understanding the structure of this fault is considered important as a picture of fault morphology (Cooper & Cowan, 2004;Gönenç, 2014;Pal & Majumdar, 2015). Apart from the structure and type of fault, it is necessary to know the model of bed depth and rock type.…”

Research has been carried out related to subsurface structures in the Tejakula Buleleng Bali area and its surroundings using the gravity method. This study aims to identify the local Tejakula fault. The data used in this study is gravity anomaly data obtained from observations of Geodetic Satellite (GEOSAT). The method used in interpreting the type of disturbance uses the Second Vertical Derivative method, which then produces two-dimensional (2D) and three-dimensional (3D) fault model interpretations. Based on the results obtained in the study, the condition of the bouguer gravity anomaly value in the Tejakula area and its surroundings at the research location is in the range of 65 mGal to 185 mGal. Meanwhile, based on the Second Vertical Derivative method in determining the type of fault, the Tejakula Fault can be categorized as a mandatory fault with an upward trend.
