Abstract.
Pore-matrix interface and pore morphology in some metamorphosed, sandstones, and igneous rocks have been investigated by small-angle neutron scattering (SANS) to reveal the fractal nature of the interface. Multiple scattering effect for these specimens has also been looked into. The fractal dimension of sandstones and metamorphosed rocks has been estimated to be 2.8 but that for igneous rocks has been found to be 2.3. An attempt has been made to explain the fractal nature of the sandstone and the metamorphosed rocks with a computer simulation model based on their formation mechanisms. SANS data indicate the existence of the upper cut-off of the fractal for igneous rocks and sandstone, but no unambiguous cut-off has been observed for metamorphosed rocks in the accessible length scale.
