  • This paper aims to investigate the value in culture, history and ecology of the Mt. Palgong. It attempts to build the strategy for making use of The Mt. Palgong by literature survey, interview, and field survey. The main results are as follows: 1) The boundary of physical geography of the Mt. Palgong is classified into two. The boundary of the Mt. Palgong limits to granite mass block in a narrow sense, while in a broad sense, the boundary of the Mt. Palgong includes a contact aureole to be bordered on the Mt. Palgong granite mass block. The boundary from a cultural viewpoint limits to Daegu city(excluding Dalseong county) and Gyeongsan city, Yeongcheon city, Gunwi county and Chilgok (Dongmyeong-myeon, Giseong-myeon) in Gyeongbuk province. 2) In the geological boundary, one of the south-west slope is clearer than that of the north-east slope of the Mt. Palgong. The landforms such as tor, sheeting joint and gutter are well developed as a whole. Mountain landform such as boulder stream, polygonal cracking is relatively well developed on the south-west slope, while river landform is relatively well developed on the north-east slope of the Mt. Palgong. 3) It is necessary to develope various masterpiece of interesting stories related to Mt. Palgong in order to make the Mt. Palgong excellent tour complex. 4) It is desirable to designate the Mt. Palgong as a national park for systematic management. A master plan should be ultimately designed to raise brand value of Daegu city, and make good identity of the city by restoring 'The Mt. Palgong Jecheondan' and registering 'Gatbawi' as world heritage. 5) It is reasonable that the method of development in The Mt. Palgong should be based on the pattern of 'slow life town'. 'The Mt. Palgong museum' will then be designed to give visitors all the informations on The Mt. Palgong.

  • This study was performed to delineate the subsurface geology, geologic structure, and distribution pattern of the Palgongsan granitic body, and to reveal the relationship between the Kyeongsang basin and Yongnam massif by gravity survey. The study area is located between the latitude of 35$^{\circ}$45'-36$^{\circ}$21'N and longitude of 128$^{\circ}$15'-129$^{\circ}$00'E. Total of 966 gravity data measured by Seoul National University, KlGAM(Korea Institute of Geology, Mining & Materials), Pusan National University and Yonsei University were used. The Bouguer gravity anomaly in the study area ranges from -12.88 to 26.01 mgal with a mean value of 11.27 mgal. A very low anomaly zone is located in the Yongnam massif in west of the study area. The anomaly value increases going from west to east. A low anomaly distribution in Palgongsan granite and Yongnam massif is interpreted as the effect of their lower density than that of Kyeongsang Super Group. Power spectrum analysis is applied to evaluate the average depth of basement the Kyeongsang Basin and Conrad discontinuity from gravity anomaly. The average depths of density discontinuities are calculated 10.45 km and 4.9 km, and these are interpreted as Conrad discontinuity and depth of basement of the Kyeongsang Basin, respectively. The depth of Palgongsan granite is derived by means of 2-dimensional modeling and it decreases gradually toward the east. The gravity anomaly east of the study area decreases abruptly due to Shingryeong fault and Nogosan ring fault. Two deepest and sharp roots of Palgongsan granite are recognized by 2-dimensional modeling of each profiles. The depths of those roots are 5.3 km on a profile AA' and 7 km on a profile BB' which is the maximum depth of Palgongsan granite. Small granitic bodies are also seen to be intruded around the Palgongsan granite. The root of Palgongsan granite is shown by 3-dimensional analysis based on the interpolation of 2-dimensional modeling along each profiles to exist in the southwest vicinity of Palgongsan granite. The total volume of Palgongsan granite is approximately 31.211 $Km^3$.

  • This research aimed to analyse geomorphic resources of Mt. palgong(in Daegu city and Gyeongbuk province) through some field surveys, and then to clarify geomorphic features. The main results are as follows. 1) The geological boundary of the south slope(granite) is more clear than one of the north slope(granite bedrock and metamorphic sedimentary rock). Small basins are along with fault line between granite bedrock and metamorphic sedimentary rock. 2) It is estimated that relatively big valleys on the north slope are due to local climate, geomorphic and geological features. 3) Tor, sheeting joint, gutter are well developed both on the south slope and on the north slope, however the development of polygonal cracking and boulder stream are more dominant on the south slope; river cliff, pool, waterfall are more dominant on the north slope with valleys that well developed. 4) Scenic geomorphic landscapes are mainly developed in Dongsan valley and Chisan valley on the north slope. 5) There are many interesting geomorphic resources in the viewpoint of storytelling in Mt. Palgong. So the specific design to utilize such resources is required

  • The rock materials from the two stone heritages in the Seonbonsa temple, Gwanbong Seokjoyeoraejwasang (stone Buddha) and three-storied Stone Pagoda, show almost identical petrographic characteristics. They are greyish white porphyritic granites which mainly consist of plagioclase, alkali feldspar, quartz, biotite, hornblende, and chlorite. The rocks from the both heritages are petrographically similar to those from the outcrops of the Palgongsan granite near the temple. Modal compositions exhibit that the rocks from the stone Buddha belong to monzogranite, whereas those from the pagoda and the outcrop near the temple correspond to syeno- to monzo granite. Whole rock magnetic susceptibility data indicate that the rocks from the stone Buddha, the pagoda, and the outcrop have nearly the same susceptibility values ranging 9-16(${\times}10^{-3}\;SI$). Gamma spectrometer data obtained from these rocks also demonstrate the same value range. In conclusion the two stone heritages in the Seonbonsa temple were made of the Palgongsan granite surrounding the temple.

  • 'This study aims to make a choice of 'the new ten beauty spots in Daegu city' based on the analysis of survey of 390 persons selected randomly. The main results are as follows. First, there is no distinctive regional character in making a choice of 'the new ten beauty spots in Daegu city'. Second, 'Gong-Ryeong-jeok-Seol(公嶺積雪) and Buk-Byeok-Hyang-Rim(北壁香林)' among 'Daegusibyeong(大丘十詠)' written by geo-jeong Seo in the Chosun(朝鮮) dynasty are included into 'The new ten beauty spots in Daegu city'. Third, The most picturesque place is Mt. Palgong in Daegu city. Fourth, most people estimate a historical nature as the most important factor in making a choice of 'The new ten beauty spots in Daegu city', but it has not been found such tendency in the selected places as 'The new ten beauty spots in Daegu city'. Fifth, both male and female have chosen Mt. Biseul, Duryu tower, Mt. Palgong and Daegu stadium as 'The new ten beauty spots in Daegu city'. Sixth, natives of Daegu as well as non-natives of Daegu tend to highly prefer Duryu tower, Mt. Biseul and Mt. Palgong.
