Any one can be approximately parallel cleavage planes in schist or foliation planes in gneisses but most appropriately I would like bedding fissility because you can distinguish both mica schistosity and foliation very well with there grain size and alternative colour basis but fissility of shale and mudstone differentiation is not common so fissility is more appropriate term for approximately parallel bedding .
