From the geological map (1:200.000 scale sheet B'Lao) the stream run into a N-S oriented granite massif of the Ca Na Complex, composed by coarse grained and porphyritic granite which intruded a volcanic complex of the Jurassic Bao Loc Fm composed by andesite, basalt, dacite , rhyodacite and other effusive rocks. Close to the quarry the contact can be observed as well as an Aplite dyke which is intruding the basalt.
A younger Basaltic complex, the Dai Nga Fm of Neogene age, is also outcropping slightly to the North and East.
Along the stream huge boulder of coarse granite, all around sands and gravels coming from the weathered granite and plenty of quartz fragments and reworked quartz crystals.
