Cleavage of a rock
WebAlthough the mineral species present in diabase often have perfect cleavage, when they are present in tiny interlocking grains, the cleavage is usually not an important durability concern when the rock is used as a construction material. Diabase Close View: In this close-up view, you can see the texture of diabase. WebCleavage is a type of rock foliation, a fabric element that describes the way planar features develop in a rock. Foliation is separated into two groups: primary and secondary. …
