The mean of soil where rocks were once present will depend on the composition of the rocks that have weathered into the soil. The mean may reflect a mix of minerals and organic matter derived from the rocks, influencing factors like nutrient content, pH, and texture of the soil. It is common for soils derived from rocks to be nutrient-rich due to the decomposition of minerals in the rocks.
Sedimentary rocks formed from living or once-living material are called organic sedimentary rocks. Examples include limestone, coal, and chalk.
Metamorphic rocks are used for building materials like marble and slate. They can also be used as decorative stones in landscaping and architecture. Some metamorphic rocks, like quartzite, are used as abrasive materials in manufacturing.
