Limestone is primarily composed of calcite and is widely used in industries like construction and agriculture. Sandstone is formed from compacted sand grains and is known for its durability and versatility. Shale is a fine-grained rock composed of clay and silt, and it has various uses ranging from brick-making to energy production.

Basalt that erupts under open air (that is, subaerially) forms three distinct types of lava or volcanic deposits: scoria; ash or cinder (); [62] and lava flows. [63] Basalt in the tops of subaerial lava flows and cinder cones will often be highly vesiculated, imparting a lightweight "frothy" texture to the rock. [64] Basaltic cinders are often red, coloured by …

What is Basalt? By definition, basalt is a dark, fine-grained volcanic rock that sometimes displays a columnar structure. It combines the durability of granite with the consistent coloring and subtlety of limestone. It lines most of the ocean floor surfaces around the world. Basalt was used to build streets and stadiums in ancient Rome.
