무안반도 소재 석장승의 원암 및 석재 공급지

Abstract

A totem pole is a guardian located in front of villages and temples who protects the village against evil spirits and other calamities. This study is to investigate the sources of rocks and areas of three Jangseungs (Seongnamri Jangseung at the Muaneup, Chongjisaji Jangseung and Beopcheonsa Jangseung at the Mongtanmyeon). Many documents of cultural assets explain the stone source of the Seongnamri Jangseung as a granite. But the rock is lithic-lappilli tuff of the Cretaceous period, which includes lithic various sizes of lithic fragment up to 10cm. The most lithic fragments are deep purple colored tuff and rhyolite. These petrographical features of the stones used for the Seongnamri Jangseung are compared with those of the lappili tuff cropped out nearby, indicating that the Jangseungs are quite similar to the lappili tuff of the Namsan at Muan-up. The literature of Cultural Properties Administration explains the source rock of Chongjisaji Jangseung as a granite. But the rocks are not granite, and differ from each other. The woman's rock is a conglomerate which has various size of pebbles up to 10cm. The men's rock is crystal-lappilli tuff which has quartz and feldspars of around 1mm in diameter. Petrographical features indicate that two rocks are derived from conglomerate layer(woman, Kcsm) and crysal tuff(man, Kct) layer of the Cretaceous period around Chongjisa temple site. The source of rocks is not referred to by name in documents for the Beopcheonsa Jangseung. The rock source of Beopcheonsa Jangseung is quartzite. The rock shows mylonitic texture by shear deformation and quartz dyke with 2cm wide. Petrographical features of the Jangseung are quite similar to the quartzite layer(qt) cropped out nearby. In conclusion, three Jangseung stones are not granite and derived from surrounding terrane.
