캐나다 Ignace 지역 심층처분장 부지의 지질모델 작성을 위한 물리탐사 적용 사례

초록

The Nuclear Waste Management Organization has developed a bedrock model, a lineament map, and a rock units model for the Revell site in the Ignace region of Canada, which is the proposed site for a deep geological repository for spent nuclear fuel. In this study, a 3D bedrock model detailing the distribution and depth of the four rock types comprising the Revell Batholith was created using 2D forward modeling and 3D inversion of aerial gravity and magnetic data. The distribution of 4,701 brittle, ductile, and dyke-type lineaments was identified using aerial magnetic and Digital Elevation Model data. Through the interpretation of seismic reflection data from 6 survey lines and vertical seismic profile data from 3 boreholes, the distribution of 31 mafic dykes was identified, and the upper and lower boundaries of the rock unit containing several mafic dykes were visualized to a depth of 1.5 km.
