basaltic
[bษหsรฆl.tษชk ]
Definition
geological term
Basaltic refers to a type of volcanic rock that is rich in iron and magnesium and low in silica. This rock is typically dark in color and has a fine-grained texture due to its rapid cooling from lava flows. Basaltic formations are commonly found around the world, typically in regions with volcanic activity. They can also play a significant role in understanding the geology of a region, as their presence indicates past volcanic activity.
Synonyms
Examples of usage
- The island is primarily composed of basaltic rock.
- Basaltic lava flows can create unique geological formations.
- Scientists study basaltic eruptions to learn more about volcanic processes.

Interesting Facts
Geology
- Basalt forms when molten lava erupts onto the Earth's surface and cools quickly, creating a fine-grained texture.
- It is one of the most common types of volcanic rock, making up about 70% of the Earth's crust and is predominantly found in oceanic islands.
- The mineral composition of basalt typically includes plagioclase, pyroxene, and olivine, giving it a diverse range of appearances and textures.
Cultural Significance
- Basalt columns, often seen like giant pillars, can be found worldwide and are famous tourist sites in places like Northern Irelandโs Giant's Causeway.
- In many Pacific Islands, basalt is used historically to construct structures, and its durability has made it a favored choice for ancient architecture.
Art and Construction
- Artists have utilized basalt for sculptures and decorative elements, valuing its unique aesthetic qualities.
- This rock is also popular in landscaping and architecture, often used for paving and stone walls due to its strength.
Environmental Impact
- Basaltic eruptions can lead to the formation of new land, significantly altering an area's landscape over time.
- These eruptions can release gases into the atmosphere, impacting air quality and regional climates temporarily.
Origin of 'basaltic'
Main points about word origin
- The word originates from the Latin term 'basaltus', which was derived from the Ancient Greek word 'basanos', meaning 'stone'.
- The term has been used since the 17th century to describe this specific type of volcanic rock.
The term 'basaltic' originates from the Latin word 'basaltus,' which itself was derived from the Greek 'basanites,' referring to a hard stone. The use of the term in geology began in the early 19th century as scientists sought to describe and classify different types of volcanic rocks. As geological studies advanced, the characteristics of basaltic rock were identified, leading to a better understanding of volcanic processes and the formation of the Earth's crust. Today, basaltic rocks are a fundamental part of earth sciences, helping researchers interpret volcanic activity and understand the composition of the Earth beneath our feet.
