  • The purpose of the work was carried out to contribute the factors related to geologic realm in the disaster stability evaluation items of the national wood culture heritages. Among the total heritages, the study targets mainly include 304 cases interpreted as a rock type in the geologic map of the bedrocks with GIS interpretation. The cases show the geologic ages, geologic provinces and rock types as the following distribution characteristics. In geologic ages, they are decreasing in the orders of Jurassic, Cretaceous, Quaternary, Precambrian, Age-unknown Cambro-Ordovician Carboniferous and Tertiary. Among the ages, the former fours occupy 285 cases (93.8%) of the targets, which show most of the wood culture heritages. In geologic provinces classified into 15, they are decreasing in the orders of Daebo intrusives, alluvium, Gyeongsang supergroup, Bulgugsa intrusives, Yeongnam massif, and Gyeonggi massif which occupy of predominant distribution 271 cases (89.1%) of them. In rock types of 52, those of 6, which are Jgr, Qa, Kp, Krt+Kav+Kav1+Kav2, Kbgr and GC2, occupy total 182 cases (59.9%) showing distinctly dominant trends from the rest of 46.
