The depositional environment of the Manhang and the Geumcheon Formation of the Pennsylvanian Gomog Croup is revealed to the shallow neritic marine milieu in this paper also as the results of Park(1963), Cheong(1975) and Kim (1976), through the analyses of stratigraphy, paleocurrent, properties of cross-beddings and sedimentational features. The formations contains some possible terrestrial sediments suggesting the paralic environment, which are however not recognized definitely within them. The paleocurrent analysis is made to the Manhang rormation only. The paleocurrent of the formation is known to belong to the shallow neritic longshore current. The paleocurrent analysis is based chiefly on the cross-bedding analysis, and subordinately on the texture of clastic coarse sediments. The paleocurrent mean is determined to 269˚, that is, from east to west, of which direction is interpreted to the right angle to the slope of the basinal depository plane and also the parallel with the depositional strike, according to Klein (1960) and Selley’s (1968) criteria. The variance value of paleocurrent directions of the Manhang Formation in the whole area studied is 6,374, and the values range from 3,394 to 6,957 according to the dirstricts. The paleocurrent pattern of the whole area shows polymodel, and the patterns in each district range from trimodel to quadrimodel. Those models approach to the shallow marine or paralic model of Tohill and Picard (1966), Picard and High (1968 a), Pisnak (1957) and Pettijohn (1962). The mean value of maximum inclinations of cross-beddings of the whole area is 19.9˚ with the standard deviation of 8.4, and ranges from 15.6˚ to 21.7˚ in the districts. Comparing the histogram showing the frequency distribution of the maximum inclinations of cross-beddings of the Manhang Formation with the Pettijohn’s (1962) histogram, it is found that the model approaches to his marine model. The Pennsylvanian Gomog Group of the coalfield is considered to have had been deposited in the pseudogeosynclinal zone on the plateau by the transgression of the Tethyan sea caused by the epirogenic movements during the Pennsylvanian Period.

This is about an environmental studt of groundwater interference by hydrodynamic dispersion between the well A and well C in Dongsam-dong, the Yeongdo Island, Pusan, Korea. The goundwater in the study wells come from the fracture zones deeply seated in welded lapilli rhyodacitic tuff of the Late Cretaceous Yucheon Group. The boring depth at the well A is 190 meters, and the optimal pumping rate of the well A is about 100 cubic meters per day therein. The fractured aquifers in impermeable welded tuff show the conjugate fracturing type and are of anisotropic. The aquifers along two fracture zones in the well A are 80 and 100 meters in depth, respectively. It is not suggested that those fractured aquifers are simply connected be tween the well A and C. The sea level fluctuation by ebb and high tides in a day is not effective to the groundwater table in the well A. The pumping for 15 days at the well A doesn't give rise to any changes of the groundwater levels in the neighbor well C. The radius of influence of the well A os measured as less than 200 meters. The measuring electric conductivity for the test of salt tracer doesn't testify any relationship between the well A and the well C. There is the main difference between the well A and the well C on the basis of the water analysis of those wells : the well A is located in the high content zone of salt much over the standard value for drinking, whereas the other wells B. C. D are in the low content area of salt below the standard value. It is elucidated for the high content zone of salt in Yeongdo around the well A to have been uplifted over 20 meters.

한국 釜山에서 발견된 世界最大規模의 구상반려암 연구 : 東洋最初의 발견 The First Discovery in Asia

The writer discovered the outcrop of the orbicular gabbro with the greatest mass in the world from Mt. Hwangryeong at the downtown area of Busan City, Korea, in 1977. The Busan orbicular gabbro is the first one found in the Asian land, though 13 localities of the orbicular gabbro were already known through the world. The gabbro embracing orbicules intruded the andesitic volcanic rocks of the late Cretaceous Yucheon Group and makes a boss. The association of the igneous reocks in this area may indicate a case of the characteristic igneous activity in the circum-Pacific area at the late Cretaceous Period. The northern peak of Mt. Hwangryeong is inferred to be a volcanic plug, because it is not only composed of fine-breccia bearing andesite, but forms the perpendicular columnar joints. The Cretaceous formation at the southeastern foot of Mt. Hwangryeong is named the Namcheondong Formation in this paper. The formation produces the Cretaceous silicified coniferale stem fossil, but it may not possible for its stratigraphic position to belong to the Sindong Group of the Cretaceous Gyeonasang System. The orbicules in the study area are commonly associated with the schlieren layering, the comb layering and the zonal structure of the calcic plagiocase. Their component minerals are the calcic plagioclase, the mafic minerals as pyroxene, olivine, hornblende and biotite, the iron-bearing minerals, and the secondary minerals as serpentine and chlorite. The SiO2 content of an orbicule sampled for the chemical analysis is 48.5%. The orbicules are generally proto-shelled or single-shelled, and exceptionally multi-shelled, showing the phaneritic texture. An orbicule in orbicule structure is first described in the world. Their core and sshells granular, radial or tangentially oriented texture. The thickness variation of th eshells is not uniform. The greatest orbiculel is in the world is described in this paper, which might be up to about 300cm in long diameter, about 200cm in intermediate diameter, and about 100cm in short diameter of the elongated ellipsoid. The orbicule at present is remained only 1/3 original size due to destructive erosion for a long time. The size of the orbicules ranges from one to 12.5cm in diameter, except the greatest one described above, but is generally less than six centimeters in diameter forming the smaller orbicules. The relatively larger orbicules of slightly more or less than 10cm in diameter occur at some places only. The orbicules of various types are commonly mingled to each other at an outcrop with the moderate size sorting. The orbicules are classified into the category with the core similar to matrix. The origin of the Busan orbicular gabbro is certainly of magmatic, being based on the field evidences explained above. The properties in the parent magma of the orbicular gabbro are thought to have been liquid phase of the low viscosity. The orbicules in the mass are supposed to have been originated by the rhythmic, cyclic or alternative supersaturation and excessive crystallization around nuclei in the gabbroic magma. the orbicules originated from the magma are inferred to be of the equivalents of the concretions in sediments or at the sea floor, the hailstones in the cumulo-nimbus clouds, limestone pearl in cavern, and oolite or pisolite in limestone. The Busan orbicular gabbro emplaced from the basic magma at the end of the Cretaceous Period is located at the southeastern border of the Asian land, as most orbicular rocks do at the other continental borders. Although the present boundary between the Eurasian plate and the Pacific plate runs along the eastern margin of the Japan Islands, it is suggested that the boundary has been located near along the southeastern Margin of the Korean peninsula at the end of the Cretaceous Period. The Busan orbicular gabbro would be authorized to the natural monument of Korea in view of its occurrence, preservation, rarity, greatness and the geological significance.

The vector mean of the 35 observations of cross-beddings of the Sindong and Hayang Groups in the vicinity of Euiseong town is calculated at 96˚. The scale and inclination of every cross-bedding are indicated in the paleocurrent map. The restoration methods by Dr. H. Okada et al and Ramsay of pretilt structure are graphically explained.
