Investigation of structural importance of Lineaments Using springs location. Case Study: Lar Region

Lineament mapping and analysis from Satellites images is an important approach for regional ýgeological and tectonic studies. In this research, the structural importance of lineaments was ýinvestigated using spatial distribution of springs in the Lar karstic catchment. Lineament maps ýwere prepared using satellite image processing and enhancement algorithms. Thematic layers, ýincluding spatial distribution of springs, drainage network and tectonic elements map were ýprepared and analyzed using Arc View10 software. The results showed that there was a close ýrelationship between spatial location of springs and distance away from faults, lineaments and ýdrainage with coefficient of determination 0.89, 0.97 and 0.85, respectively. Correlation of ýlineaments general trend with tectonic elements and also close relationships between tectonic ýelements length and lineaments with springs location, showed the structural origin of the ýlineaments. ý
