What type of texture do clastic sedimentary rocks have?
Geology & LandformExamples of clastic sedimentary rocks are sandstone and conglomerate. Some clastic sedimentary rocks (such as shale and mudstone) are fine enough that the individual grains cannot be distinguished. These fine-grained rocks are said to have an aphanitic texture. What is the texture of clastic sedimentary rock? Clastic texture: grains or clasts do not interlock but
