FISSURE VEIN Meaning and
Definition
-
A fissure vein is a geological term referring to a narrow fracture or crack in rock formations that is filled with minerals such as quartz, calcite, or other crystalline materials. This type of vein is commonly found in various types of rocks, including sedimentary, metamorphic, and volcanic formations.
Unlike other types of veins, which form through the deposition of material along bedding planes or fractures, a fissure vein originates from the actual opening and subsequent filling of a narrow crack or fissure. These veins can vary in width, ranging from a few millimeters to several centimeters or even meters.
The formation of fissure veins is typically associated with tectonic activity, such as earthquakes or the movement of the Earth's crust. As the rock is subjected to stress, it may crack or fracture, providing pathways for fluids to flow through. Over time, these fluids can carry dissolved minerals, which precipitate out of the fluid and crystallize within the fissure, creating the vein.
Fissure veins are often highly mineralized and can contain economically valuable deposits of minerals, including gold, silver, copper, and lead. Because of their linear and elongated nature, fissure veins can extend both horizontally and vertically within rock formations, sometimes connecting to deeper or shallower mineralized zones.
Geologists study fissure veins to understand the geological processes that led to their formation and can use their presence as indicators of potential mineral deposits. Mining companies may also target areas with fissure veins for mineral exploration and extraction.

Etymology of FISSURE VEIN
The word "fissure" is derived from the Latin word "fissura", which means "a narrow opening or crack". It dates back to the early 17th century.
The word "vein" has a different etymology and originates from the Latin word "vēna", meaning "a blood vessel or a natural channel". It can be traced back to the Proto-Indo-European root "weh₁-", which meant "to weave or to wind".
When these two words are combined to form "fissure vein", it refers to a mineral vein or deposit found within a narrow crack or opening in rock formations.
