Suoi Cat is the name of a stream that run NW of Dai Lao Village, about 10 Km west of Bao Loc,Lam Dong Province the place can be reached in about 4 Km fro the village, the road is good and asphalted for the first 2-3 Km after that, approaching the site became unpaved and quite sandy, all around tea and coffee’ plantations, the road pass by a big quarry where the altered granite is quarried for sand and concrete.
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.
