Limestone Sedimentary rocks

Limestone is a very common sedimentary rock consisting of calcium carbonate (more than 50%). It is the most common non-siliciclastic (sandstone and shale are common siliciclastic rocks) sedimentary rock. Limestones are rocks that are composed of mostly calcium carbonate (minerals calcite or aragonite).

Rock (geology) Wikipedia

Metamorphic rocks are formed by subjecting any rock type—sedimentary rock, igneous rock or another older metamorphic rock—to different temperature and pressure conditions than those in which the original rock was formed. This process is called metamorphism, meaning to change in form.The result is a profound change in physical properties and chemistry of the stone.

More on identifying rocks minerals

Sandstone like shale, this is a clastic or detrital sedimentary rock-- originating from the weathering and breakdown of other rocks. Sandstone was formed from grains of sand instead of silt or clay, so its final appearance is that of a rock made of compacted sand. You can see these sand grains with a magnifying lens, sometimes without one.
