Simple 2D gravity–density inversion for the modeling of the basin basement: example from the Banat area, Serbia
We have developed a technique to calculate lateral density distribution of the sedimentary basin basement by combining linear gravity–density inversion and 2D forward modeling. The procedure requires gravity anomaly data, depth-to-basement data and density data for the sediments (density–depth distribution). Gravity efect of density variations in the basement was extracted from the total gravity anomaly by removing the joint efect of the sediments with vertical density variations and homogeneous basement of average density contrast (calculated by 2D modeling). Gravity ...Ivana Vasiljević, Snežana Ignjatović, Dragana Đurić.

Definisanje strukturnih odnosa primenom postupka horizontalni gradijent
Različiti postupci matematičkih transformacija se mogu primeniti na gravimetrijskim i magne tometrijskim podacima, kako bi se na istražnom terenu definisali strukturno-tektonski odnosi. U radu su prikazani rezultati dobijeni korišćenjem postupka horizontalni gradijent i ukupni horizontalni gradijent na gravimetrisjkim podacima. Navedeni postupci su pomogli da se detektuju kontakti sa velikim padnim uglom (vertikalni ili subvertikalni kontakti), koji se mogu interpretirati kao rasedi. Za test područije uzet je istražni prostor koji se nalazi na jugoistoku Srbije u okolini Vranjskog basena.

Defining structural correlation using of total horizontal gradient
Gravity data can help to define the structural correlation along significant vertical shifts. The different procedures of mathematical transformations on gravity data are applied to define structural correlations. The paper presents the results obtained using the procedure total horizontal gradient on gravity data. The application of the total horizontal gradient helped to detect contacts with a large dip angle (vertical or subvertical contacts), which can be interpreted as faults. The study area located in the wider area of the ...Snežana Ignjatović, Ivana Vasiljević, Milanka Negovanović.

Fault type assessment based on vertical gravity gradient anomalies – advantages and limitations
The type of dip-slip faults can be assessed based on the analysis of vertical gravity gradients. Theoretically, just a simple comparation of the gradient extreme values can give us an answer whether the fault is normal or reverse (thrust). Practical application of this method is far more complicated and the results depend on a number of parameters, such as a complexity of geological setting, the quality of gravity data, dip angle and displacement of the fault, density contrast, etc. ...... limitations Ivana Vasiljević, Snežana Ignjatović, Branislav Sretković Дигитални репозиторијум Рударско-геолошког факултета Универзитета у Београду [ДР РГФ] Fault type assessment based on vertical gravity gradient anomalies – advantages and limitations | Ivana Vasiljević, Snežana Ignjatović, Branislav Sretković ...
