THE ROLE OF FAULTS IN THE FORMATION OF THE OKHOTNICHYA CAVE (BAIKAL REGION)

The paper presents the results of an analysis faults different ranks near Okhotnichya Cave in Pribaikalye, aimed at identifying their role formation and evolution cave its adjacent areas. This was done using rank-wise structural-paragenetic faults, which forms basis a specialized mapping tool for fault zones. Factual evidence obtained through several methods. speleoinitiating fracture network studied based on digital topographic survey performed Leica DistoX 310 laser rangefinder. therewith-generated 3D-model allowed making up detailed plan passages linking to local geological-structural observations with mass measurements studying dip directions strike orientations fractures. stated that correspond paragenesis right-lateral NNE trending strike-slip fault. Local rock fracturing within made it possible determine type kinematics fractures verify reconstruction zone supra-local level. It has been narrow tunnels follow NNE- WNW-oriented large chambers grottoes extension structures - ENE- NE-striking normal faults. lineament cave-adjacent area revealed is element regional fault, typical late-orogenic Baikal rift system. Thus, conducted research showed genesis mixed character provided possibility analyzing karst caves' spatial patterns reconstruct kinematic types hierarchic levels local, supra-local, regional.
