Stone -monuments, distributed in this area, have been investigated and studied in geological and conservational points of view. They are seemed to have been mainly built from the Shilla to Koryeo Kingdom, although more systematic studies are needed. The used rocks in these monuments are mainly biotite granite and hornblende-biotite granite of Jurassic age. The rock phases are nearly identical to those which are distributed in the area. The two rock phases are nearly same in the characteristics of minevalogy and texture except the amount of hornblende. However, hornblende-biotite granite characteristically contains aggregates of mafic minerals which are frequently observable in the monuments. They are mainly influenced by chemical weathering due to warm, abundant rainfall, and salty moisture because of being adjacent to the sea. Some cracks are secondarily developed which may be due to strong chemical weathering and influence of sculpturing. For conservation, it must be scientifically considered based on characteristics and kind of rock phase, factors on weathering process, situation and protection. |
