Abstract

A study of the overall linear expansion of carbonate rock cores in an alkaline environment was extended to include the distribution of expansion along the length of the core. For the material tested, it was found that the fracture pattern, radial expansion and overall linear expansion were associated with bedding planes and stylolitic seams. The formation of voids and the constant association of iron stains both with pyrite and expansion zones places pyrite under suspicion as an indicator of a type of expansive lithology. The radial expansion distribution provides a basis for separating expansive and non-expansive lengths of core. The analyses of the chemical and physical properties of the differential lengths of core might then be used to describe the nature of changes found in differential expansion.
