Shale is the most common sedimentary rock, accounting for about 70 percent of the rock in the Earth's crust. Shale is a fine-grained rock made from compacted mud and clay. The defining characteristic of shale is its ability to break into layers or fissility. Black and gray shale are common, but the rock can occur in any color.14.3.8.1 Porous rock. Porous rock contains empty space in which fluids, such as compressed air, can be stored. Porosity is defined as the percentage of a rock that is empty and can be used for storage.

Limestone and sandstone are highly porous and readily absorb liquids, and are particularly prone to etching, and wearing away when they come into contact with acids. Marble is also fairly porous but not as much as limestone and sandstone. Staining is also a problem with more porous stones, especially darkly-colored liquids like red wine.These rocks are often called clastic sedimentary rocks. One of the best-known clastic sedimentary rocks is sandstone. Sandstone is formed from layers of sandy sediment that is compacted and lithified. …This solid fabric of stone is less porous than sandstone.
