Stone-monuments, distributed in this area, have been investigated and studied in geological and conservational points of view. They are seemed to have been built from the Shilla to Koryeo Kingdoms, although more systematic studies are needed. The used rocks in these monuments are mainly biotite granite of Jurassic age. They are strongly weathered and partly exfoliated along igneous lineation about 1-2 mm(maximum up to 5 mm). They are mainly effected by chemical weathering to be selectively dissolved and by various kind of moss. For conservation, it must be scientifically considered based on characteristics and kind of rock phase, factors on weathering process, situation and protection.
