What is fissures rock?

Fissure rock is a type of igneous rock that forms when magma cools and solidifies in long, narrow cracks and fissures in the earth's crust. These cracks are typically found in volcanic areas and can be several meters wide and hundreds of meters deep.

Fissure rocks are usually dark in color and have a fine-grained texture due to the rapid cooling of magma in the narrow and shallow fissures. Some common examples of fissure rocks include basalt, andesite, and diabase.

Fissure rocks are an important source of building materials, as they are relatively hard and durable. They can also be used as a decorative stone for landscaping and monuments. Additionally, fissure rocks can be used as a raw material for the production of pavement, tiles, and other construction materials.
