Sandstones with more than 15% silt and clay are called wackes (e.g., quartz wacke, lithic wacke). It’s worth taking a closer look at the different types of sandstone because sandstone is a common and important sedimentary rock. Typical sandstone compositions are shown in Figure \(\PageIndex{6}\).Limestone is a relatively soft rock with a Mohs hardness of 3, which means it can be easily scratched. It has a specific gravity of 2.7-2.9, which makes it less dense than most other rocks. It is typically soluble in acidic solutions, which is why limestone landscapes often feature caves, sinkholes, and other karst formations. Type of LimestoneHence, the term “sand” without qualification is imagined to be composed of quartz mostly. However, sand is a natural mixture which means that it is never pure. By no means can one say that quartz and sand are the same thing. Consolidated sand is a rock type known as sandstone.

The layers of sandstone layers can be found in each part and around 20 - 25% of these layers are found. Sandstones, typically, have much higher porosities (10–35%) because the individual sand or mineral grains don’t fit together closely, allowing larger pore spaces. Porosity measurements of Wisconsin rocks. The porosities of the rocks measured vary from 2% to more than 30%. Much of this variation is due to lithology (rock type). ...
