Grain Boundary Parameters in Sandstone and Limestone
In this paper, length of grain-to-grain contact, number of contacts per grain and ratios between the length of contacts and geometric characteristics of grains in heterogeneous Berea sandstone and Indiana limestone are studied. It is shown how hydrostatic pressure up to 40 MPa influences these grain boundary parameters. Observations show that there are different types of influence of hydrostatic pressure on grain boundary parameters in the studied sandstone and limestone.
