Permeability tensor calculated from fracture mapping in the Horoman peridotite complex

Permeability is a measure of how fluid flow occurs through rocks, which governs 16 fluid migration in the basement rock formations. This study evaluated three-dimensional 17 permeability and its anisotropy in the Horoman peridotite complex from geometric 18 information of fractures using a scan line method. The results showed that the field-scale 19 permeability ranges from 10-13 to 10-12 m2, with the maximum principal permeability 20 subparallel to the layered structure of the peridotites. 21 22
