Abstract

In order to develop a new mineral exploration technique, a study was carried out about the potential mapping of Moisan area using SIP (Spectral Induced Polarization) data. The SIP inversion results were classified according to the geological regions, and the distribution characteristics of resistivity and phase values of SIP data were analyzed at the ore region. Based on the characteristics of SIP of ore bodies, we performed 3D potential mapping of Moisan area. The analyzed potential map was verified using that the locations and patterns of high potential regions of the results are well matched with those of the known ore bodies. If we get the higher spatial resolution SIP data, the potential mapping technique using SIP data can be effectively applied to the estimation of mining deposit.

광물자원탐사 기술 개발의 일환으로 광대역 유도분극 탐사 자료를 활용한 광체의 부존 가능성 평가를 위해 모이산 지역에 대한 3차원 포텐셜 지도 구축 연구가 수행되었다. 현장 탐사 결과를 지질모델링 영역별로 해석하여 광체 영역에서 나타나는 위상 및 전기비저항 값의 분포 특성을 해석하였으며, 이를 바탕으로 모이산 광체에 대한 부존 잠재성 평가를 수행하였다. 잠재성 평가 결과 기존에 확인된 광체 영역에서는 높은 부존 가능성이 확인되었으며, 최근 시추를 통해 확인된 일부 광체 영역에서도 주변부에 비해 잠재성이 높은 것으로 해석되어 신뢰도가 높음을 확인하였다. 광체 분포특성에 따라 효과적으로 측선 설계가 이루어지고 보다 조밀한 광대역 유도분극 탐사 자료를 얻을 경우 이번 연구를 통해 습득한 해석 기술은 광체 평가에 효율적으로 적용될 수 있을 것으로 판단된다.
