  • 고성능 핵자탐기를 이용하여 1988. 6. 11부터 6. 30까지 충남 공주 송산리 고분군의 탐사를 수행했다. 고분탐사의 표본으로 이미 알고 있는 전축분 6호분과 석축분 5호분을 동시에 탐사결과 백제당시 높은 온도로 구어 만든 벽돌로 축성된 6호분에서는 5호분보다 아주 강한 고지자기반응을 보여주었다. 그리고 탐사지역 Ａ지역과 Ｄ지역에서는 고지자기반응이 어떠한 일정한 양상을 따라 나타났다. 이들은 각각 석열(石列) 혹은 석축열(石築列)였음을 발견했다. 또한 Ｄ지역의 강한 고지자기 반응에서는 백제시대의 토기항아리가 발견되었다. 이번 탐사의 결과로 고지자기탐사는 높은 열처리와 관계된 고고학적 유적, 유물탐사에 매우 유리하다는 것을 알게 되었다.

  • Paleomagnetic studies have made remarkable contributions to the understanding of many geological aspects of Korea for the last 40 years, such as the collisional processes of Korean Peninsula, the development of basins in relation with fault systems, the opening and evolution of the East Sea, and the reconstruction of paleogeographic configuration. These contributions have played an important role in the escalation of geology in Korea by elucidating the mechanisms on Processes of fragmentation and amalgamation of the Peninsula, mountain building, igneous activities, metamorphism, and folding and faulting based on the view of plate tectonics. This paper is intended to introduce and summarize the paleomagnetic research papers designed to decipher the tectonic processes of Korea, according to the geologic ages of the studied rocks.

  • A paleomagnetic study was carried out on three gravity cores recovered from the KODOS-90 area in the North Pacific to obtain a magnetostratigraphic information and to correlate the magnetic records between cores. The sediments bear a stable remanent magnetization and the polarity sequence of the three cores can be correlated with the gomagnetic polarity time scale for the Plio-Pleistocene. The abrupt change in the magnetic susceptibility profile at 285 cm depth of the gravity core 26 indicates the presence of a major hiatus. The average sedimentation rates of the gravity cores 08 and 26 are about 2.7 and 1.4 times higher than that of the gravity core 20 (0.09 cm/100yr), respectively.

  • Detail downward variation records for paleomagnetic, XRD, photospectrogram, TOC results were obtained from the soil developed along the Hantan River, Gungpyeong-ri, Cheongsan-myeon, Yeoncheon-gun Gyeonggi-do. The unconsoildated sediments underlain by the Jeongok Quaternary Basalt indicates that the paleosol formed twice with different ages, as apparently indicated by sedimentological, paleomagnatic, and soil chemical properties. The paleosols recorded paleoclimate and paleoenvironments of about 271.21$\pm$89.8 ka before eruption of the Quaternary Jeongok Basalt.
