For the guide to the inquiry learning of the Korean high school earth science education, the experiments of the earth science must be carried out as much as possible in the educational spot. By the analysis and the comparison on the experiments in the present four earth science text books of the high school in Korea and the ESCP earth science text book (Investigating the Earth), the ratios of the experiments of the present four earth science text books to the ESCP textbook range from 16.4% to 31.5% and the ratio of total four text books is about 65.8%. The above data imply that the inquiry learning of the Korean high school earth science education is doubtful. For the inquiry learning of the earth science education, the teachers must carry out all the experiments (48 items) in the present four text books and fill up vacancies from the ESCP experiments etc. Also all the experiments in the present four earth science text books were actually put into operation and some defects and ambiguities of the experiment processes are pointed out. Finally improvable suggestions for the experiments are presented.

禹榮均 公州大學校 基礎科學硏究所 1996 自然科學硏究 Vol.5 No.-

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.

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.

충남 비봉사문석광상 일대에 분포하는 초염기성암체의 변질작용

우영균,박종삼 公州大學校 基礎科學硏究所 2003 自然科學硏究 Vol.10 No.-

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.

Romey의 方法에 따른 高等學校 地球科學 敎科書의 分析

禹榮均,李義雨,金熙洙 공주대학교 사범대학 과학교육연구소 1993 과학교육연구 Vol.24 No.1

Science Ⅰ(2) and Earth Science, the high school textbooks by the 5th curriculu, were analyzed by Romey`s method and analytic results were compard. The results of Science Ⅰ(2) textbooks are as follows: In the contents, the index of students involvement ranges from 0.16 to 0.02. The average indices in each chapter of 8 different textbooks are 0.08, 0.10, 0.09, 0.08 and 0.05. The maximum index is in chapter Ⅱ and the maximum index chapter Ⅴ. In the figures and tables, the index of students involvement ranges from 1.00 to 0.00. The average indices in each chapter of 8 different textbooks are 0.29, 0.25, 0.21, 0.25 and 0.14. The maximum index is in chapter Ⅰ and the minimum index in chapterⅤ. In the exrecises, the index of student involvement ranges from 1.50 to 0.00. The average indices in each chapter of 8 different textbooks are 0.45, 0.23, 0.33, 0.25 and 0.31. The maximum index is in chapter Ⅰ and the minimum index in chapterⅡ. The results of Earth Science textbooks are as follows: In the contents, the index of student involvement ranges from 0.15 to 0.00. The average indices in each chapter of 7 different textbooks are 0.07, 0.06, 0.04 and 0.04. The maximum index is in chapter Ⅰ and the minimum index in chapter Ⅲ and Ⅵ. In the figures and tables, the index of student involvement ranges from 0.67 to 0.00. The average in each chapter of 7 different textbooks are 0.17, 0.21, 0.15 and 0.04. The maximum index is in chapter Ⅱ and the minimum index in chapter Ⅵ. In the exercises, the index of student ranges from 1.00 to 0.00. The average indices in each chapter of 7 different textbooks are 0.23, 0.32, 0.40 and 0.35. The maximum index is in chapter Ⅲ and the minimum index in chapter Ⅰ. The suitable involvement index for inquiry learning should be over 0.40(Romey, 1968), but the indices shown above are below 0.40. Therefore, as a whole, it is considered that Science Ⅰ(2) and Earth Science textbooks by the 5th curriculum are not suitable for inquiry learning. But, partly, ordering contents, figures and tables, and exercises index of student involvement is seen the progressive tendency to 0.40. Therefore, figures and tables than contents, and exercises than figures and tables, and Science Ⅰ(2) than Earth Science are more inquiring. And, according to the textbooks, or chapters, or contents, figures and tables, exercises, index of student involvement are partly higher than 0.40. There would be the possibility of raising the index value of the textbooks if the writer would pay more times, attentions and endeavors in editing new textbooks.

花崗岩類中의 角閃石에 對한 硏究

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.

According to anaiyses of earth science curricula and textbooks for elemantary, middle and high school(Table 1∼8), it is clear that the effective learnings about the important factors in geologic part such as minerals, rocks, weathering, erosion, transportation, deposition, geologic structure, strata, fossils, geologic survey and ore deposits, can be obtained through the field work investigation. In the Kongju area, various types of igneous, sedimentary and matanmorphic rocks are distributed, so there are plenty of the various field geologic practical materials. Therefore Kongju area is the suitable place for the developments of field geologic practical courses(Figure 1). In our present school circumstance, it is difficult that the field geologic time is especially shared. Therefore it is desirable that the field geologic practical work is concurrently acted in the chance of the annual school functions such as picnic and camping. So the field geologic practical courses developed here are the adequate place for picnics and campings.

By the survey of the problems about the laboratory works of the 5th high school earth science curriculum, four major problems were discovered in the curriculum, textbooks, experimental environments and evaluations. In the view of these problems, I`d like to suggest the following activation plans of the earth science laboratory works in the high school. 1. In the earth science curriculum, the detailed guides such as increasing the numbers of laboratory works and the presentation of the laboratory works division must be printed distinctly so as to be made good use of the successful writing the textbooks and the guidance of investigative learning. 2. The textbook must be edited to accomplish the investigative learning, especially laboratory works according to the aim of the curriculum. 3. We must secure enough laboratory rooms, experimental materials and assistants and decreasing teacher`s duty as soon as possible in order to accomplish the effective laboratory works. 4. But the most important point of all is that the entrance examination for college must be improved adjust to evaluate the student`s ability of the investigative learning in science.

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.
