The dark fine-grained unit represents the dike, while the light-colored layers are dominantly layered sandstones, or country rock. The purple zone between these represents the "baked" margin of the country rock. This sliver of rock was essentially roasted during magma injection.The view below is looking along the dike. Notice how prominent the ...layers increases if more layer boundaries (e.g. per cm) are present and more weak minerals. The Brazilian tensile strength of studied layered Modave sandstone is larger for larger quartz grains, while fracture length parallel to the layers is smaller. Quartz grains in the studied layered sandstone are classified as fine sand. In order to investigate the mechanical properties and permeability characteristics of sandstone during damage evolution under hydromechanical condition, a series of coupled hydro-mechanical triaxial tests on sandstone specimens were conducted based on the Rock Top 50HT full-stress multi-field coupling triaxial test system.
