Abstract

Examination of microcracks in crystalline rocks has shown that the open microcracks form a spatially continuous network that communicates with larger openings. The open cracks become filled with new minerals that often contain U and LREEs. The crystalline rocks most desirable as a host for a repository have low crack porosity, moderate alteration, and occur in an environment that promotes rapid sealing.
