The development of geographic information systems and their growing application in Geology provide a unique opportunity to optimize the process of lineaments identification on images of the Earth’s surface using the resources of laptops. The selection of primary linear objects is based on their searching in images in the form of linear and relatively extended boundaries between contrasting areas and/or sequences of pixels of the same tone. Such an analysis is performed for a large gold field in Eastern Sakha (Yakutia) territory to identify regional and local lineaments. Generally accepted models proposed to explain the orientation of faults in a homogeneous medium are used to interpret the results. Lineaments are found in the Taryn gold field that probably correspond to tectonic faults from three stages of compression. The assumed mutual position of the axes of the main normal stresses at different stages of deformation is confirmed by results from lineament analysis, interpreting the fracturing of an outcrop in the Bolshoi Taryn river valley, and exploratory drilling data.
