Abstract During rock drilling, a drill bit will wear as it breaks the rock. However, there is no uniform grading standard for rock abrasiveness. To solve this problem, the wear mechanisms of a polycrystalline diamond compact (PDC) bit and the formati

Mafic dykes in continents are a special type of intrusive rock formed by different tectonic events including earlier fracturing deformation in host rocks and successive magma intrusions originating at depth. Dyke swarms indicate regional crustal defo
