what is the classification of stone

 

Stones can be classified based on their origin, composition, and structure. The main categories are:

1. **Igneous Stones**: Formed from the cooling and solidification of magma or lava. Examples include granite (intrusive) and basalt (extrusive).

2. **Sedimentary Stones**: Created from the accumulation and compaction of sediments. They often contain fossils. Examples are limestone, sandstone, and shale.

3. **Metamorphic Stones**: Formed from the alteration of existing rocks through heat, pressure, or chemical processes. Examples include marble (from limestone) and schist.

Each category reflects a different geological process, which influences the stone’s characteristics and uses.
