Hornblende Meaning: Definition, Examples, and Translations
๐
hornblende
[หhษrnหblษnd ]
Definition
mineral composition
Hornblende is a common and important mineral of the amphibole group and is characterized by its complex silicate structure. It typically occurs in igneous and metamorphic rocks and is recognized for its dark green to black color. The mineral often appears in granite and diorite, contributing to the overall composition and texture of these rocks. Hornblende is significant not only for its geological applications but also for understanding the conditions of rock formation.
Synonyms
amphibole, hornblende rock.
Examples of usage
- The granite contained a significant amount of hornblende.
- Geologists often study hornblende to reveal the history of rock formation.
- Hornblende crystal structures can indicate the temperature and pressure conditions during metamorphism.

Interesting Facts
Geology
- Hornblende is a common mineral found in igneous and metamorphic rocks, particularly in granite and basalt, contributing to the rockโs durability.
- It is part of the amphibole group of minerals, which means it forms in high-temperature and high-pressure environments deep in the Earth.
Economic Importance
- Hornblende can indicate the presence of valuable metals, making it significant in mineral exploration.
- Because of its heat resistance, hornblende can also be used in the production of heat-resistant materials.
Cultural Significance
- In some indigenous cultures, stones containing hornblende are used for making tools due to their toughness and availability.
- Collectors value hornblende for its unique appearance, leading to its use in decorative items and as a specimen in geological displays.
Science
- The study of hornblende can provide insights into geological processes, such as plate tectonics and the formation of the Earth's crust.
- Researchers use hornblende to date rocks and understand the history of the Earth through a technique called radiometric dating.
Origin of 'hornblende'
Main points about word origin
- The name 'hornblende' comes from the German term 'Hornblend' which means 'horn' and 'to blend', referring to its horn-like appearance and blend of colors.
- It was first described in the 18th century by a Swedish mineralogist, showing how the study of minerals evolved over time.
The term 'hornblende' originates from the German word 'Hornblende', which means 'horn' (from 'Horn') and 'blende' (which refers to a variety of minerals that are commonly shiny or lustrous). The name reflects the mineral's horn-like appearance and its association with other blende minerals. It was first identified in the late 18th century by miners and geologists in Europe, as they examined the diverse mineral compositions of the region's geological formations. Over time, the study of hornblende has expanded, leading to a greater understanding of its role in various rock types and geological processes. The systematic study of hornblende also contributed to the broader field of mineralogy, helping to classify other amphiboles and establishing connections between mineral features and environmental conditions during rock formation. As a result, hornblende remains a subject of interest in both academic research and practical geology.
