A quantitative study on the variational features of rock properties followed by weathering in granites

Upon the basis of the measurements of index properties and ultrasonic velocities as well as the determination of degree of weathering mainly based on microscopic observation, relatively fare correlation has been found between the degrees of weathering and the physical properties of rocks, particularly between degrees of weathering and maximun water content. A significantly better correlation has been obtained between degree of weathering and P wave velocity by grouping rock samples according to rock facies. This study presented the range of physical parameters corresponding to each degree of weathering in granites.
