비봉사문석광상의 초염기성암은 주로 사문암이고, 소량의 사문암기원의 활석과 석면이 포함된다. 이 사문암은 크게 I, II 및 III형으로 구분된다. I 형으로부터 III형까지의 순서는 사문석화작용의 일반적인 진행방향이고, 이 사문암은 해즈버자이트와 같은 맨틀기원 초염기성암의 사문석화작용으로, 그리고 주요 활석화작용은 사문암과 편마암 또는 페그마타이트 간의 경계부 그리고 사문암내 열극들을 따르는 사문석의 열수변질작용에 의하여 형성되었다고 해석된다. The ultramafic rocks in the Beebong serpentine ore deposits are composed mainly of serpentinite, and have small amount of talc and asbestos originated from serpentinite. The serpentinite are largely divided into three rock types of I, II and III. It is analysed that the order from I to III is the general trend of serpentinization and the serpentinite have been formed by serpentinization of the mantle origin ultramafic rock such as harzburgite, and major steatitization have been formed by hydrothermal alteration of serpentine through the boundary cracks between serpentinite and gneiss or pegmatite, and fissures in serpentinite.

Most of the fluorite ore deposits in Kumsan district occur in the Chinsan area. Specifically, these are the Okgye, Hyongyang, Ilyang, Manak fluorite ore deposits. Field survey and fluid inclusion study were undertaken to illustrate the characters and origin of the fluorite ore deposits in Chinsan area. The results of this study are as follows; Gology of the Chinsan area is composed of Majonri Formation and Changri Fomation which belong to Okchon Group and Jurassic biotite granite and Cretaceous pink feldspar granite and quartz porphyry. The wall rock of fluorite ore deposits in Chinsan area are chiefly limestone in Majonri Formation and partly limestone in Changri Formation. The relevent igneous rocks of the fluorite ore deposits are chiefly quartz porphyry, but some are biotite granite or pinkfeldspar granite. The fluorite ore deposits in this area are chiefly contact metasomatic deposits which were formed while limestones were intruded by quartz porphyry, biotite granite and pink feldspar granite. The filling degrees of fluid inclusions in fluorite ranges 84∼95% in Okgye, 85∼95% in Hyongyang, 85∼91% in Ilyang, 92∼96% in Manak ore deposits. The salinity (NaCl equivalent weight percent) ranges 0.1∼1.5wt.% in Hyongyang. 0.3∼2.8wt.% in Ilyang. 0∼1.5wt.% in Manak ore deposits. The homogenization temperature of fluorite ore deposits in Chinsan area ranges 97.6∼191.6C in Okgye, 99∼168.4C in Hyongyang. 100∼214C in Ilyang, 122∼248.6C in Okgye, 99∼168.4C in Hyongyang, 100∼214C in Ilyang, 122∼248.6C in Manak ore deposits. These data indicate that Chinsan Fluorite ore deposits belong to the epithemal or mesothemal deposits same as the other fluorite ore deposits in Korea.

Coicis Semen is one of the oriental medicine that has been used for the treatment of the disease such as pulmonary abscess, periappendicular abscess and wart since ancient times. However, the mechanism of the action of the drug is not well studied. This study was done to investigate the effects of Coicis Semen on the host defense mechanism. Effects of Coicis Semen on the immune responses were analyzed by measuring the contact gypersensitivity, hemagglutinin, hemolysin and rosette formation, cytotoxicity, and reactive oxygen intermidiates production. As the results, water extract of Coicis Semen administration enhanced the antibodies (hemagglutinin and hemolysin) formation and the appearance of rosette forming cells of the spleen. Also Coicis Semen increased the allogeneic immune response in the mouse, showed cytotoxic activity against human leukemia cell line(K562) and decreased the contact hypersensitivity against dinitroflurobenzene. Also administration of Coicis Semen slightly increased NK cell activity and enhanced the production of such reactive oxygen intermidiates as superoxide and hydrogen peroxide from the macrophages in vivo and in vitro. The above results demonstrate that Coicis Semen has enhancing effects on cellular and humoral immune responses against disease.

비봉사문석광상의 사문암들은 주로 사문석으로 구성되어 있으며 이 밖에 소량의 감람석, 휘석, 감섬석, 자철석, 크롬철석, 녹니석, 금운모 및 활석을 포함한다. 감람석과 휘석은 그 결정경계나 결정내의 간극을 따라 사문석화가 진행되므로 기원암의 잔류광물이다. 이 사문암을 엽리와 반상변정의 발달정도에 따라 구분해 보면 8개군으로 나뉘고, 사문석화작용은 엽리와 반상변정이 잘 발달된 것에서 미약해지는 방향으로 진행된다. 사문석은 가상조직은 망상조직 및 아우어글래스조직과 비가상조직인 관통조직 및 결합조직을 가지며, 사문석화가 진행됨에 따라 사문석의 조직은 가상조직에서 비가상조직으로 변화한다. 사문암은 주고 SiO₂(35.91∼39.81 wt.%, 평균37.84 wt.%)와 MgO(39.84∼41.23 wt.%, 평균40.67 wt.%)로 구성되어 있으며 소량의 Fe₂O₃(6.06∼8.87wt.%, 평균7.41wt.%)를 포함한다. 미량성분으로는 특히 Cr(>1100ppm)과 Ni(>1660ppm)이 많다. 이 값들은 McDonough(1990)가 제시한 전세계 감람암의 평균치와 유사하고, 이 사문암의 회토류원소 분석치를 원시맨틀값으로 표준화한 자료에 의하면, 비교적 사문석화가 덜 된 것은 1에 접근하므로 그 기원암은 맨틀기원의 초염기성암이다. 이 사문암의 기원암은 알파인형 맨틀기원의 초염기성암인 더나이트, 헤즈버자이트 및 레조라이트였고 기원암으로부터의 주 사문석화작용은 이 지역 주변암이 받은 녹색편암상 내지 각섬암상의 광역변성작용시에 일어났다고 해석된다. Serpentinites of Beebong serpentine ore deposits are composed mainly of serpentines with some olivine, pyroxene, amphibole, magnetite, chromite, talc, chlorite and phlogopite. Olivines and pyroxenes were serpentinized along the crystal boundaries and/or cracks in the crystals. It means that olivine and pyroxene are relict minerals of original ultramafic rocks. These serpentinites are subdivided 8 groups according to the degree of foliation and content of porphyroblast, and the serpentinization were progressed from the developed foliation and porphyroblast to the weaked. Serpentines have pseudomorphic texture such as mesh and hourglass texture, and non-pseudomorphic texture such as interpenerating and interlocking texture, The pseudomorphic texture are changed to the non-pseudomorphic texture along the progress of sepentinization. The serpentinites have high SiO₂(35.91~39.81 wt%, av.37.84 wt.%) and Mg0(39.37~42.72wt%, av.40.67wt%) with small amount Fe₂O₃^(*)(6.06~8.87wt%, av.7.41 wt.%) and have high Cr(>1100ppm) and Ni(>1660ppm) in minor elements. These values are similar to the data of whole world average peridotites(McDonough, 1990). Because the standardized REE data of less serpentinized serpentinites by primitive mantle values are nearly 1, the original rock of these serpentinites are considered as the mantle origin ultramafic rock. It is considered that the original rocks of these serpentinites was mantle origin alpine type ultrarnafic rocks such as dunite, harzburgite and lherzolite and the main serpentinization from these original rocks was formed by the regional metamorphism of greenschist to amphibolite metamorphic facies.

광천사문석광상 사문암은 총 연장 약 2,000m, 최대폭 약 30m의 렌즈상 내지 맥상으로 북북동 내지 북동방향에 따라 선캄브리아기의 월현리층을 관입하였는데, 사문암과 직접 접한 암석은 각섬석편암이다. 광천사문암은 주로 50%이상의 사문석으로 구성되었으며 기원암의 잔류광물인 감람석, 휘석 및 각섬석이 소량 포함된다. 감람석과 휘석은 결정경계나 결정내 균열을 따라 사문석화되었다. 감람석으로부터 사문석화 할 때에는 MeO와 FeO값이 감소하였고 SiO₂값은 별 변화가 없다. 사문석 결정 주변의 망상조직으로 발달된 자철석은 사문석화과정에서 빠져나온 철로부터 형성된 것으로 해석된다. 한편, 휘석으로부터 사문석화 할 때에는 SiO₂값은 크게 감소하고, MgO 값은 약간 증가하였으나 FeO값은 약간 감소하였다. 광천사문암의 기원암은 더나이트와 휘석감람암 또는 해즈버자이트라고 해석되며, 이 기원암으로부터의 주사문석화작용은 광역변성작용에 의하여 이루어졌다고 해석된다. Serpentinites of Kwangcheon serpentine ore deposits occur mainly in Weolhyeon-riformation as NNE to NS trending lenticular to vein type body. They extend for about 2000m long and have maximum width of about 30m. Most country rocks very contacted with serpentinite are amphibole schists. Kwangcheon serpentinites are mainly composed of more than 50% serpentine, but partly have original minerals such as olivine, pyroxene and hornblende. Olivine and pyroxene were serpentinized along the crystal boundaries and/or cracks in the crystals. On the process from olivine to serpentine, MgO and FeO values are decreased and SiO₂values are nearly not changed. It is considered that mesh-texture magnetite around the serpentine crystals was formed from the iron which had been left out through this serpentinization process. But, on the process from pyroxene to serpentine, SiO₂values are much decreased, and MgO values are slightly increased and FeO values are slightly decreased. Also, it is considered that the original rocks of Kwangcheon serpentinites was mantle origin ultramafic rock such as dunite and, pyroxene peridotite or harzburzite, and main serpentinization of Kwangcheon serpentinites from these original rocks was formed by the regional metamorphism of greenschist to amphibolite facies.

충남지역의 사문암은 암색과 입도등에서 다양한 특징을 보이지만, 거의 모든 암석이 주로 사문석으로 이루어졌으며, 암석에 따라 감람석과 휘석의 잔류체와 자철석, 크롬철석, 금운모, 녹니석, 투섬석 등의 부성분광물을 다양하게 포함한다. 활석광석은 주로 미립의 활석으로 이루어져 있으며 소량 의 녹니석류, 운모류, 각섬석류, 탄산염광물류등을 포함한다. 사문암은 육안적 특징과 광물조합에 따라 크게 I, II, III의 세가지 암형으로 구분되는데, I型에서 III型으로의 순서는 사문석화작용의 일반적인 경향으로 해석된다. 사문암의 기원암은 맨틀기원의 초염기성암인 해즈버자이트였으며, 사문암은 이 기원암이 사문석화작용을 받아서 이루어졌다고 해석된다. 그리고 주활석화작용은 사문암과 편마암 또는 거정질화강암과의 경계부와 사문암내의 파쇄대를 따라 상승하는 열수용액에 의하여 사문암이 변질작용을 받아 이루어졌다고 해석된다. The serpentinites in Choongnam area have various characteristics such as rock colors and grain sizes etc., but the most rocks are composed mainly of serpentine minerals, and have some various mineral contents of the relicts of olivine and pyroxene, magnetite, chromite, phlogopite, chlorite and tremolite etc.. Talc ore is composed mainly of fine talcs, and has small amounts of chlorites, micas, amphiboles, and carbonates etc.. The serpentinites are largely divided into three rock types of I, II and III by the megascopic character and mineral assemblages. It is considered that the order from I to III is the general trend of serpentinizaion. Also, it is considered that the serpentinites have been formed by serpentinization of the mantle origin ultramafic rock such as hazburgite, and the major steatitization have been formed by hydrothermal alteration of serpentine through the boundary cracks between serpentinite and gneiss or pegmatite, and fissures in serpentinites.

Within amphibole domains, there is a significant decrease in unit-cell content of Al with increasing SiO₂ content. Decrease in Na₂O₂, K₂O and TiO₂ are conspiccuously related to decrease in Al₂O₃. The compositional trends measured in amphiboles is interpreted as reflecting crystallization under progressively more oxidizing condition. The average Fe/(Fe+Mg) for amphiboles changes from 0.76 in hornblende granite to 0.52 in porphyrytic granite and from 0.57 in monzonite to 0.29 in granodiorite. In Kimhae area, the oxidation ratio and fo₂ of porphyritic granite are higher than those of hornblende granite. In Finnmarka area, those of granodiorite are higher than those of monzonite. The chemical composition of the amphiboles of porphyrytic granite and monzonite is hornblende, that of hornblende granite is ferrohastingitic hornblende, and that of monzonite is edenitic hornblende. It is supposed that porphyrytic granite and granodiorite were crystal lized in low temperature, high fo₂ and post magmatic environment compare to hornblende granite and monzonite.
