Title : Tectonic evolution and structural style of hun graben in westreen part of Sirte Basin, Libya
Abstract:
Sirt Basin it is one of the largest oil and natural gas producing basins in Libya, the majority content of the know hydrocarbons reserved in Libya was formed during the Mesozoic( Elakkari, 2005). This basin represents different depositional environments, ranging from continental to marine deposits, which enabled a favorable configuration of different source and reservoir rocks, as well as seals within the basin.
Hun Graben is located in the north central in Libya, and is an elongated structure feature, has a distinct surface expression and forms a present day fault bounded depression indicating that it is one of the youngest tectonic elements in the region. The application of analysis of geophysical data is useful for studying the subsurface. It is used in this research to study the structural frame work of Hun Graben. Where we integrate the result from geophysical methods with the analysis of surface maps.
This application shows how a GIS in combination with geological data sets can be used to solve specific geological problems. We applied the Arc map software on digital image to processing focuses to gain a better understanding of Remote Sensing products. Advanced image processing techniques are introduced and applied using Landsat Thematic Mapper data of the Hun Graben area. We used the results of gravity and magnetic data processing and overlaid them on Landsat data maps and matched the results with the geological map of the region to produce a new tectonic map for the study area.
