Abstract

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.

NWMO는 사용후핵연료 심층처분장 부지인 캐나다 Ignace 지역 Revell 부지에서 기반암 모델, 선구조도와 암층 모델을 작성하였다. 항공 중력 및 자력 자료에 2차원 순산 모델링과 3차원 역산을 적용하여 Revell Batholith를 구성하는 4가지 암종의 분포 범위와 심도에 대한 3차원 기반암 모델을 작성하였다. 항공 자력 및 DEM 자료를 이용하여 총 4,701개의 취성, 연성 및 암맥 선구조의 분포를 파악하였다. 6개 측선의 반사법 자료와 3개 시추공에서의 VSP 자료에 대한 해석을 통해 총 31개의 고철질 암맥의 분포를 파악하였으며, 고철질 암맥이 다수 포함된 암층의 상단 및 하단 경계를 1.5 km 심도까지 영상화하였다.
