Gravel Gravel and sand are both porous and permeable, making them good aquifer materialsIs chalk permeable or impermeable? WiseAnswerChalk is a soft, white, porous, sedimentary carbonate rockIt is a form of limestone composed of the mineral calcite and originally formed deep under the sea by the compression of microscopic plankton that had settled to the sea floorChalk is common throughout Western Europe, where deposits underlie parts of France, and steep cliffs are often seen where they meet the sea in Chalk Wikipedia"Limestone" means any rock formed mostly of calcium carbonate (CaCO 3), but to geologists, limestone is only one of several types of "carbonate rocks" These rocks are composed of more than 50% carbonate minerals, generally the minerals calcite (pure CaCO 3) or dolomite (calciummagnesium carbonate, CaMg[CO 3] 2) or bothLimestone: The Calcium Carbonate Chemical Sedimentary Rock
