  abstract = {{T}he {A}lborz is a region of active deformation within the {A}rabia-{E}urasia collision zone. {T}he {A}br and the {K}hij {F}aults are two {NE}-trending left-lateral strike-slip faults in the eastern {A}lborz that correspond to the {S}hahrud fault system extended through an area of about 95 km x 55 km. {T}ectonic landforms typically associated with active strike-slip faults, such as deflected stream channels, offset ridges and fault scarps are documented along the mentioned faults. {D}etailed analyses of satellite images and digital topographic data accompanied by field surveys allowed us to measure horizontal offsets of about 420 +/- 50 m and 400 +/- 50 m for the {A}br and {K}hij {F}aults, respectively. {A} total of 8 quartz-rich samples were sampled and dated from two different fan surfaces using in situ-produced {B}e-10 cosmogenic dating method. {M}inimum exposure ages for the abandonment of the alluvial fan surfaces of 115 +/- 14 kyr along the {A}br {F}ault and of 230 +/- 16 kyr along the {K}hij {F}ault imply that both faults are active with slip rates of about 3-4 mm yr(-1) and 1-3 mm yr(-1), respectively. {T}he results of our study provide the first direct quantitative geological estimates of slip rate along these two active faults and place a new constraint on slip distribution between the faults in the eastern {A}lborz. {F}ault kinematic studies (from fault slip data) indicate a {N}35 degrees {E}-trending maximum stress axis comprising a dominant strike-slip regime in agreement with the geomorphological analyses. {T}he left-lateral strike-slip faulting along the {A}br and {K}hij {F}aults and their associated fault zones in the eastern {A}lborz can be due to the westward component of motion of the {S}outh {C}aspian {B}asin with respect to {E}urasia and {C}entral {I}ran.},
