Definition of vug in English: vugnoun vʌɡvəɡ Geology A cavity in rock, lined with mineral crystals. Example sentencesExamples - Cavities or vugs in the centre of the veins make it possible for minerals to grow into free space forming large and well-formed crystals.
- The banded quartz is fascinating to study; euhedral crystals originally deposited in vugs and cavities were repeatedly covered with thin bands of agate.
- Very narrow vugs containing quartz crystals are encountered in the quartz seams at times, but these invariably are barren of gold.
- Veins in some septaria do not fill the fractures completely but form elongated vugs that are sometimes lined with well-formed crystals.
- It occurred as a fine-grained siliceous vein filling and as discrete, clear, tiny crystals in vugs.
Synonyms space, chamber, hollow, hole, pocket, pouch
Derivatives adjective Geology Pyrargyrite was a dominant mineral, occurring locally in vuggy masses, in the Cortland mine, Gunnison County. Example sentencesExamples - During the mid-to-late 1970s some spectacular specimens were produced from a vuggy to cavernous fissure zone intersected by an exploration drift on the 17 level.
- Small pegmatites within the granite are locally abundant and have furnished a large number of minerals from pockets and associated vuggy zones.
- During a nine-week period a vuggy zone about 250 feet inside the main haulage adit of the Mountain Monarch mine was exploited, and many fine rhodochrosite crystal groups were collected.
- Unlike the vein deposits, the metasomatic flats are frequently vuggy and are the source of most crystallized mineral specimens from the district.
adjective Geology Usually the section drilled by the second drill rod below the first occurrence of fine, vugular porosity yields oil. Example sentencesExamples - The product is effective when drilling formations that are fractured or vugular and when drilling highly porous formations.
- Rock with cavernous or vugular porosity occurs only in a few thin zones in the Floridan aquifer system, except in the Lower Floridan aquifer.
- We then obtain micro-scale computations of flow in such vugular media on very fine grids that resolve the geometry of the vugs.
- It is believed that the gels have not chemically degraded, but that the water eventually finds another fracture or vugular system to travel through.
