Metabasites and metapelites in the Mungyong area were intruded by Cretaceous granites with radius of 4-8 km. As the distance from granite body increases, the mineral assemblage of metabasite changes from amphibole + plagioclase through amphibole + plagioclase + epidote to amphibole + plagioclase + epidote + chlorite. The compositional variations of amphibole and plagioclase according to the change of metamorphic grade and bulk rock compositions are very complex. Towards the Mungyong Cretaceous granite body, the mineral assemblage of metapelite changes from chlorite+ muscovite(ch1orite zone) through biotite + chlorite + muscovite(biotite zone) to andalusite+biotite + muscovite${\pm}$chlorite or cordierite+ biotite+ muscovite${\pm}$chlorite(cordierite zone). The estimated metamorphic conditions of cordierite zone are 480~$580^{\circ}C$ 1.5-3.3 kb. The theoretical study on the thermal metamorphism caused by the Cretaceous granite with radius longer than 4 km in the Mungyong area suggests the followings: The degree of metamorphism is mainly determined not by the size of granite body but by the temperature of granite intrusion; The country rocks within 2 km from Cretaceous granite have undergone metamorphism with temperature higher than $500^{\circ}C$, which is consistent with the petrological study in the Mungyong area. Mungyong Cretaceous granite caused a low P/T thermal metamorphism to the country rocks; the amphibolite facies metamorphism to the country rocks within 1-2 km from the granite body and the epidote-amphibolite and greenschist facies metamorphism to the country rocks within 2-5 km.

Field relationships indicate that the Jumchon granite intruded the Pyungan Supergroup but the Daedong Supergroup overlies Jumchon granite nonconformably. This relationship suggests that the Jumchon granite intruded after the sedimentation of the Pyungan Supergroup (at Late Permian or younger), but before the sedimentation of the Daedong Supergroup (at Early Triassic). The Jumchon granite intruded thrusts within Pyungan Supergroup indicating that the thrust event occurred after the sedimentation of the Pyungan Supergroup but before the intrusion of Jumchon granite. This justifies a narrow age bracket of the first thrusting event of the Mungyeong area, from Late Permian to Early Triassic. In other localities, rocks of the Daedong Supergroup override the rocks of Pyungan Supergroup by thrusts, indicating that another thrust event occurred after sedimentation of the Daedong Supergroup (after Early Devonian).

While the lecture activities in Simwonsa, Ganjae Jeon Wu(1841~1922) has established a "law of lecture activities" which was an ritual between a teacher and pupil, between the couple. Through this way he expected to recover the former ritual, even within their own school. In 1884 he built a "law of Sidong school", meaning to build a large object, elementary scholarship will serve as the rules of conduct, and argued that human nature mainly served to the core in the course of study. Ganjae in Mungyeong area was also discussing studies with Song Byeong-hwa(1852~1916) and received correspondence with scholars in areas related to Mungyeong. They were Kim Jae-kyung(1841~1926) and Park Se-hwa (1834~1910). Ganjae had also some big national events on the sojourn time in Mungyeong. In 1882 there were army incident, in 1884 there were a command of the government that people must pull on western clothes. Ganjae did not follow the command of the government. Someone asked "Can we not follow the command of the government?" Ganjae replied "We have a right to resist to the illegal command of the government. There were also 1884's Gapsin-coup, Ganjae saw that we must defend the country by rejecting foreign power and keeping our rituals. Given the above, the timing that Ganjae lectured in Mungyeong personally was a time that provided a clue to establish his core ideas. Nationally it was a time that must defend the country from foreign nations. Ganjae had faith that for keeping the country we must keep firmly our own rituals.

자연광물자원의 채광으로 조성되거나 자연적으로 생겨난 동굴은 사람들이 평소에 경험할 수 없는 신비한 체험을 제공할 수 있는 관광자원으로도 활용될 수 있다. 현재 우리나라에 있는 동굴의 수는 260개소에 달한다. 그 중에서 천연기념물로 지정된 동굴이 12개소, 지방기념물로 지정된 동굴이 29개소이며, 나머지 219개소의 동굴은 미지정 상태로 남아있다. 이에 따라 본 연구에서는 경북지역을 사례로 하여 동굴의 관광적 특성을 살펴보았다. 경북지역에는 천연기넘물 1개소, 지방기념물 2개소, 특수동굴 2개소, 기타동굴 13개소 등 18개소의 동굴이 분포하고 있다. 18개소의 동굴중 개방 동굴은 울진에 있는 성류굴이 유일하며, 동굴의 지역별 분포를 보면 문경에 절반에 해당하는 동굴이 분포하고 있는데 이것은 문경이 다른 지역과 달리 석회암과 무연탄이 많이 분포하여 예전부터 시멘트공장과 연탄공장이 발달한 것에서 그 연유를 찾을 수 있다. 봉화에 4개소가 있으며, 울진에 2개소, 경주, 영주, 안동 등에 각각 1개소씩 분포하고 있다.

The metamorphic environments occrrred in the Sadong and the Gobangsan formations were studied through the investigation of chloritoid and white mica in shales at Munkyung area. Two types of white mica occurs in the shale of Sadong formation; muscovite-dominant ($Mu_{76.1}Pa_{18.1}Ma_{5.8}$) and margarite-dominant ($Ma_{52.9}Mu_{31.6}Pa_{15.5}$). It is inferred that the muscovite-dominant white mica is generated by the diagenesis of Na-rich illite whereas the margarite-dominant white mica is generated by reactions between calcite and pyrophyllite separated from illite. In shales of the Gobangsan formation, chloritoids are observed with muscovite, pyrophyllite and chlorite. The chloritoids of the Gobangsan formation are considered to be originated from the reaction between pyrophyllite and chlorite. The Sadong and Gobangsan formations would have experienced the low-temperature metamorphism (anchizone) considering that white mica in general forms above the temperature of $200^{\circ}C$ and the assemblage of chloritoid-pyrophyllite-chlorite is stabilized below $280^{\circ}C$.
