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.
