Building stones can be divided into two groups: raw stone and stone product. In Korea, they consist of granite, diorite, gabbro, andesite, tuff, slate and marble, of which granite is main product. The disribution area is approximately $31,753km^2$. The enterprises of building stone are about 1,500 at present. The granites for building stone are biotite granite, hornblende granite. granodiorite and porphyritic granite, of different colors (white, pink, grey, green and black). The compressive strength of granite ranges from 813 to $1,338kg/cm^2$, hardness from 78 to 101 and water absorption ratio from 0.09 to 0.40%. The weight reduction ratio of granite for 14 hours in aqua regia+$KMnO_4$solution is 0.3~4.5wt.%. There are eighty granite quarries in Korea. Marbles can also be extensively used for building but only a few mines are operated at present.

泉의 地質學的 考察

申柄雨 淸州大學校 1960 論文集 Vol.3 No.1

In this thesis, I tried to synthesize and systematize the methods of classification, geological stuctures, and effects of springs, whieh were described in old documents concerning springs. Particularly, I referred to the effects of sprigs and methods of taking a bath of a hot spring, and emphasized the close relationship between human life and a spring, The summary of the thesis is as follows, (1) The underground water which naturally gushed forth to the surface of ground. is cold spring the water of a hot spring is a combination of underground water and magnatic water. (2) Springs are calassified as ferrous springs, saline springs, bitter springs, carbonate springs, alkaline springs, acidic springs, sulphur springs, salts springs, and radioactive springs according to the components of springs, (3) Springs are classifiecl as water-table springs, pervious ledge springs, fissure springs, and dynamic springs accoording to the geological structures. (4) The quality of springs depends upon the sursoundings of springs and components of rocks and location of springs. The distrribution of spring temperature is helpful to conclude the shapes and distribution of the bodies supplying heat of spring. (5) The effects of springs are direct or indirect. (6) Springs have the close relationship with our human life covering agriculture, mining, and so on.

Wollastonite을 중심(中心)으로 한 규산질비료광물자원(珪酸質肥料鑛物資源)에 관(關)한 연구(硏究)

신병우,Shin, Byung Woo 대한자원환경지질학회 1972 자원환경지질 Vol.5 No.4

Through the series of study on the above subjects, the following were founded. 1. Soluble silica in paddy top-soil (xppm) and maxium possible yield (y) is expressed as following equatic $y=63.97+0.425x-0.00114x^2$ It is known that soluble silica in paddy top-soil in South Korea is limited as 130ppm. 2. Gnder the present Korean condition 90% of paddy-top-soil is estimated to be short in available silica content and the country average to only 78ppm. 3. The total area of Korean paddy-top-soil is about 1,036,710 ha. All requirements of wollastonite in South Korea estimated from the equation $Y=0.94-0.033{\times}$are about 2 million M/T 4. Silicates fertilizer minerals are Bentonite, Zeolite, Wollastonite, Serpentine, and Chlorite. But Wollastonite is most economic and can be supplied to using Korea. 5. Wollastonite is formed in contact metomorphic deposits. Limestone is the country rock of wollastonite. Limestone in Korea is in Ryunchcon system, (Pre-cambrian) Okcheon system, (unknown), Great limestone series (paleozoic), Hongjum series (Paleozoic) and Kyungsang system (mesozoic) so that the zones of these limestone and igneous rock are the possible area which wollastonite can be produced. 6. According to the published geologic map (scale 1/5000), about 25 provinces will be possible area which wollastonite can be produced. In future, I believe that many possible area will be increased. 7. According to this survey at Danyang, total wollastonite resources are about 179,000 M/T and average of soluble $SiO_2$ is 29.84%. 8. According to this survey at Daijeon, total resources are about 57,600 M/T and average of soluble $SiO_2$ is 21.53%. 9. Total wollastonite resources including Danyang, Yangduk, and Daijeon are about 1,172,200 M/T. Considering possible resources, it will be over 20 million M/T and I can say that it is possible to be supply for a score.

남한(南韓)의 지구조운동(地構造運動)과 금속광상(金屬鑛床)

From the point of view of geological history, the land of South Korea is regarded as the subject of processes of the changes in formations of several geological blocks such as Kyonggi massif, Yeongnam massif, Taebaegsan basin, Kyungsang basin and so on. Through the long period of geological chronology, the present topography and geotectonics have been formed by the complicate interactions of epirogenetic movements, magmatism, orogenesis, differential vertical movements, metamorphism and sedimentation. The reason of the crust movements mentioned above, is suppossed that the Pacific and West Pacific plate have subducted directly or indirectly into the East Asia plate. This fact can be endorsed by the results of the studies on the heat flow, gravity anomaly, absolute age dating, tectonic lineation, lithofacies and the temperature of hot spring in South Korea. The formations of metal ore deposits as well as other geological processes can be determined by the mechanical control of the plates and be divided into several systematic patterns. The investigation of about 110 metal mines in South Korea shows the following results. (1) Plate boundary volcanic type is about 28% (2) Plate boundary plutonic type is about 44% (3) Intraplate sedimentary type is about 26% (4) Intraplate magmatic type is about 2%.

앵커 정착부를 확공하여 구형모양의 구근을 형성하여 인발력을 증대시키는 펄스방전장치를 개발하여 경제적이고 안정성 있는 앵커시공을 하는데 목적이 있다. 실험을 통해 펄스파워장비의 전기적 특성을 알아내었고, 그에 따른 에너지변화로 발생된 동적압력을 측정하였다. 여기서 측정된 동적압력이 앵커 정착부 주변지반에 충격력을 주는 확공 압력이며, 이 압력은 앵커 정착 부동다짐 효과로 확공 및 천공 면 다짐효과를 주어 보다 큰 마찰저항으로 인발력 증대에 크게 기여할 것으로 추정된다. This study intends to develop a pulse discharge device to strengthen the pushing power by expanding the cavity of the anchor settlement to form a spheric root for the purpose of constructing the economical and stable anchor. Through the experiments, the electrical characteristics of the pulse power equipment had been identified it and the dynamic pressure generated from the subsequent change had been measured. Here, the measured dynamic pressure is the cavity expansion pressure to impact on the ground around the anchor settlement. Since this pressure has effects of cavity expansion and bored surface hardening with dynamic hardening effects on the anchor settlement, it is expected that it will largely contribute the increase of pushing power with a strong frictional resistance.

When the electricity is not flowing because the certain distance lies between positive (+) pole and negative (-) pole of electricity, we call the status as the air insulation. When the voltage is gradually increased to this status, the electricity is flowing breaking this insulation status at certain point, which we define as the insulation is broken. When the insulation is broken, big expansion pressure is occurred, which is the essence of technology of pulse discharge of electricity. We are utilizing this technology of pulse discharge of electricity to expand and press the cavity of ground foundation of anchor settlement with the aim of making the anchor body with great pushing power. The results of measuring the pressure at the experiment of chamber model generated are average 8 MPa with 250 mm of diameter (at 5000 voltage applied), and 16 MPa with 110mm (at 3500 voltage applied) respectively. This is direct pressure working to the wall of chamber which is equivalent to the wall of anchor settlement part where the intensity of pressure generated can be adjusted by regulating the voltage. In the future, it shall be verified about applicability to the ground through experiment of electricity discharge on the real ground; and the increase of pushing power through the expansion and press of cavity.
