VESICULAR TEXTURE Meaning and
Definition
-
Vesicular texture refers to a specific type of texture found in certain rocks and minerals, characterized by the presence of small hollow cavities or vesicles within the material. These vesicles are often irregular or spherical in shape and can range in size from tiny microscopic pores to larger openings visible to the naked eye. This distinctive texture is formed during the process of volcanic activity or other geological processes that involve the rapid cooling and solidification of molten material.
When molten rock, known as magma, rises to the Earth's surface through volcanic eruptions, it encounters a decrease in pressure, causing the dissolved gases within the magma to form bubbles or vesicles. As the magma cools and hardens into rock, these gas bubbles become trapped within the solidified matrix, resulting in the formation of vesicles. The size and distribution of these vesicles can hold valuable information about the specific conditions and processes that occurred during the rock's formation.
Vesicular texture is commonly observed in rocks such as basalt, pumice, and scoria, which are products of volcanic or pyroclastic activity. This porous texture is also exhibited by some sedimentary rocks like certain types of limestone, where the vesicles are formed due to the dissolution of certain minerals. The presence of vesicles in rocks can affect their physical properties, including porosity, permeability, and strength, and can also influence their suitability for various applications such as construction, architecture, and industrial uses.
Etymology of VESICULAR TEXTURE
The word "vesicular" comes from the Latin word "vesicula", which means "a small bladder" or "a blister". The suffix "-ar" in "vesicular" is used to form adjectives.
The word "texture" comes from the Latin word "textura", which means "a weaving". The suffix "-ure" in "texture" is a noun-forming suffix.
When these two words are combined, "vesicular texture" refers to the texture of a material or rock that contains small bladder-like or blister-like voids or cavities.
