Historically, clinicians have given the posterior cruciate ligament as a structure which performs a relatively unimportant function in the background of the knee joint, subservient to the medial, lateral and anteriar cruciate ligaments. The reason for this are its hidden positin, its reiatively inaccessiblity and a superficial knowledge of functional anatomy. The functional and pathologic anatomy is now more widely understood by many authors. In view of the increasing incidence of knee injuries, greater stress is being placed on the importance of early clinical recognition. The author have, therefore summarized the anatomy and clinical biomechanics of the posterior cruciate ligaments in detail with the objective of gaining a more accurate understanding of their function and with the aim of improving the diagnostic and therapeutic approach to posterior cruciate injuries. The posterior cruciate ligament is narroweat in its middle portion and fanned out superiorly and to a lesaer extend inferiorly. Inferiorly the ligmament is attached to the posterior limit of the intercondylar strip of the tibia and to a small area behind and distal to this point. It passes upwards and forwards to be attached to the front of the intercondylar surface of the medial femoral condyle. This ligament consists of two parts, anterior and posterior bands. The posterior band is tight in extension and anterior in flexion. The posterior curciate ligament is the principal structure preventing posterior translation of the tibia and also this ligament would be a check against extreme hyperextension only after the anterior cruciate ligament has been severed. In knees with insufficiency of posterior cruciate legament the greatest increase in posterior displacement occurres at 75 to 90 degrees of knee flexion and minimum posterior translation at zero to 30 degrees.

유구활석광상지역의 초염기성암은 주로 사문암이고, 소량의 각성암과 활석광체를 포함한다. 사문암은 유구편마암을 암상상으로 관입하였고, 후에 유구편마암과 함께 변형되었다. 이 사문암은 더나이트 및 페리도타이트와 같은 맨틀기원의 초염기성암으로부터 사문석화작용에 의하여 형성되었으며, 사문석화작용은 초기의 자변성작용과 후기의 각섬암상의 광역변성작용시 변질에 의하여 이루어진 것으로 해석된다. The ultramafic rocks of the Yoogoo talc ore deposits area consist mainly of serpentinite with some amphibolite and talc ore body. Serpentinite intruded as the sill form into the Yoogoo gneiss, and later deformed together with the Yoogoo gneiss. It seems that the serpentinite was originated from the mantle origin ultramafic rocks such as dunite and peridotite by serpentinization, and the serpentinization was depended on the early autometamorphism of dunite and peridotite, and the later regional metamorphism at amphibolite facies.

유구활석광상 지역의 지질은 주로 선캄브리아기의 유구편마암과 이를 관입한 시대미상의 초염기성암으로 구성되어 있다. 초염기성암은 주로 사문암이고 소량의 각섬암과 활석광체를 포함한다. 사문암은 유구활석광상의 모암이고, 주활석화작용은 파쇄대를 따라 상승한 열수용액에 의한 사문암의 열수변질작용으로 이루어졌다. The geology of the Yoogoo talc ore deposits area is composed mainly of pre-Cambrian Yoogoo gneiss and unknown age ultramafic rock intruded into the Yoogoo gneiss. The ultramafic rocks consist mainly of sepentinite with some amphibolite and talc ore body. The serpentinite is the parent rock of the Yoogoo talc ore deposits, and major steatitization was depended on the hydrothermal alteration of sepentinite by ascending hydrothermal solution through the shear zone.

Many skarn type iron ore deposits are distributed in Kimhae-Mulgeum area of Gyeongnam Province. Integrated field, mineralogic, geochemical and fluid inclusion studies were undertaken to illustrate the character and origin of the ores in this area. The iron ore deposits in this area are NS or NNE trending fracture filling magnetite veins which are developed in andesitic rocks near the contact with late Cretaceous micrographic granite bodies. Symmetrically zoned skarns are commonly developed in the magnetite veins of this area. Zoning of skarn from center to margin of the vein are as follows; garnet quartz skarn-epidote skarn-epidote orthoclase skarn-altered andesitic rocks. Major ore mineral is magnetite and small amount of hematite, pyrite, pyrrhotite, chalcopyrite and sphalerite are associated. Vein paragenesis reveals four depositional stages; 1) skarn stage, 2) iron sulfide and oxide stage, 3) skarn stage, 4) sulfide stage Minute halite-bearing polyphase inclusions and liquid inclusions are contained in quartz. Filling temperatures range from $257^{\circ}$ to $370^{\circ}C$.

Many hydrothermal skarn-type iron ore deposits inchiding Mulgeum, Yangseong, Maeri and Kimhae mines are distributed in the south-eastern Gyeongnam Province, Korea. The deposits are magnetite veins which occurred in propylitized andesitic rock near the contact with late Cretaceous Masanite. Symmetrical zoned skarns are commonly developed around the magnetite veins. The order of the skarn zones from the vein is garnet-quartz skarn, epidote skarn, and epidote-orthoclase skarn. The garnets include isotropic or anisotropic andradite($Ad_{100{\sim}70}$), and the epidotes are composed of pistacite($Ps_{21-31}$). Fe contents of the epidotes generally increase toward the magnetite veins. Epidotes and garnets often show compositional variations from grain to grain, that is, their Fe and Al contents vary inversely. This suggests that the variations depend mainly upon $fo_2$ during the skarnization. Oxygen and carbon isotope analyses of minerals from andesitic rock, micrographic granite, major skarn zones and post-mineralization zones were conducted to provide the information on the formation temperature, the origin and the evolution of the hydrothermal solution forming the iron ore deposits. Becoming more distant from the ore vein, temperatures of skarn zones represent the decreasing tendency, but most ${\delta}O^{18}$ and ${\delta}O^{18}_{H_2O}$ values of skarn minerals represent no variation trend, and also the values are relatively low. Judging from all the isotopic data from the ore deposits, the major source of hydrothemal solution altering the skarn zones and precipitating the ore bodies was magmatic water derived from the more deeply seated micrographic granite. This high temperature hydrothermal solution rising through the fissures of propylitized andesitic rock was mixed with some meteoric water, and the extensive isotopic exchange occurred with the propylitized andesitic rock. During this process, the temperature and ${\delta}O^{18}_{H_2O}$ value of hydrothermal solution were lowered gradually. At the stage of iron ore precipitation, because after all the alteration was already finished, the oxygen isotopic exchange with the wall rock was nearly not taken. The relatively high ${\delta}O^{18}$ and ${\delta}O^{18}_{H_2O}$, and relatively low ${\delta}C^{13}$ values of calcites of post mineralization stage, are the results of leaching of the high ${\delta}O^{18}$ chert xenolith in the andesitic rock and low ${\delta}C^{13}$ andesitic rock.

Field and microscopic evidence, XRD,EPMA and chemical data suggest that parent rock of talc ore deposits of Yesan district was originated from ultramafic igneous rock. Parent rock can be divided into serpentinized dunite, serpentinized peridotite, metagabbro, amphibolite and hornblende schist. The ore deposits are highly sheared, and show many evidences of hydrothermal alteration and metamorphism at the greenschist and albite-epidote amphibolite facies. The process of steatitization is variable depending upon the composition, and the degree of alteration and metamorphism of the parent rocks. Steatitization can be divided into two processes with or without serpentinization. The parent rocks with serpentinization are serpentinized dunite, serpentinized peridotite and metagabbro, showing the following alteration process; olivine ${\rightarrow}$ serpentine${\rightarrow}$ talc. The rocks without serpentinization are amphibolite and hornblende schist showing the following sequence; hornblende${\rightarrow}$ chlorite${\rightarrow}$ talc. Formation of talc deposits is summarized as following six stages; I) Intrusion of ultramafic rocks, 2) autometamorphism, 3) metamorphism at greenschist and albite-epidote-amphibolite facies, 4) brittle deformation, 5) hydrothermal alteration, 6) purification of low-grade talc by late dyke intrusion.

홍성, 광천, 광시 사문석광상 사문암은 선캠브리아기의 각섬석편암과 화강편마암내에 NS-NE 도는 NW망향의 불연속적인 렌즈상으로 관입한 시대미상의 초염기성암이 사문석화된 것이다. 이 사문암은 주로 SiO₂와 MgO로 이루어져 잇고, Cr과 Ni값이 낮다. 이 사문암의 기원암은 맨틀기원의 초염기성암인 더나이트, 휘석감람암 또는 해즈버자이트였고, 이로부터의 주사문석화작용은 녹색편암상 내지 각섬암상의 광역변성작용시에 이루어졌다고 해석된다. Serpentinites of Hongseong, Kwangcheon and Gwangsi serpentine ore deposits were formed by serpentinization from the unknown age ultramafic igneous rock bodies which intruded as NS-NE or NW trending discontineous lenticular bodies in pre-Cambrian amphibole schist and granite gneiss. The serpentinites have high SiO_2(av. 38.83wt.%) and MaO(av. 39.63wt.%) and have high Cr(>1030ppm) and Ni(>1438ppm) in minor elements. It is considered that the original rocks of these serpentinites were mantle origin ultramafic rocks such as dunite and pyroxene peridotite and/or harzburgite, and main serpentinization from there original rocks was formed by the regional metamorphism of greenschist to amphibolite metamorphic facies.
