Abstract
Boryung sandstone and Yeosan marble were thermally cracked at predetermined temperatures ranging $200^{\circ}C$ to $600^{\circ}C$. Optical microscopy was utilized to observe thermally induced cracks and physical properties such as specific gravity, effective porosity k elastic wave velocity were measured. Optical observations show that all crystal boundaries of Yeosan marble heated to $600^{\circ}C$ open and new intracrystalline cracks seem to be occurred in all crystals, but developments of thermal cracks in Boryung sandstone heated to $600^{\circ}C$ are not pronounced. From $200^{\circ}C$ upwards, effective porosity and elastic wave velocity of Yeosan marble are sharpely increased, whereas effective porosity and elastic wave velocity of Boryung sandstone are weakly increased.
Keywords
