The closed Pond of gourigol is a part of tectonical area of bostan abad according tostructural geomorphology view. studing the bostan abad area through the photoes, wecan take it as anticlinarium which is founed in the mountain making phases of latesenozoic ara, and is a continum to the folding of the Neogen formation of North-easttabriz. Gourigol lake, like other neigh bouring areas has been formed in the earlyQuaternary ara.due to neotectonic movements and resulted in the formation of somefault in the West-North and East-South directions. it has moved the upper cretaceousflysch formations and has caused to theGourigol, tectonic basin.There are two parallel fault beside the lake.
