    What is graywacke sandstone made of?
    This type of sandstone contains fewer grains made of quartz and more made of feldspars, volcanic rock fragments, as well as silt and clay than most sandstone. It is therefore also known as “dirty sandstone.” The volcanic rock fragments give graywacke a greenish-gray color. What makes the beds in graywacke?

    What is sandstone made of?
    In general, sandstone is made of sand grains which originated from older rocks that have been broken apart and worn down. The sand grains are usually made of quartz or feldspar, but can be almost any mineral. Binding these grains together is cement, which is typically made of silica, calcite, or iron oxide.

    Is sandstone a well-cemented rock?
    Sandstone is typically a well-cemented rock, meaning that the sand grains are held together by some type of mineral cement, such as silica, calcium carbonate, or iron oxide. The degree of cementation can vary, and this can affect the strength and durability of the rock.
