- n. Plural form of vug.
Sorry, no etymologies found.
It might have been in some comments elsewhere, or maybe in something I haven't posted yet: the occurrence of hydrocarbons in vugs in silicified, Hg-bearing, Au-anomalous serpentinite near the McLaughlin gold mine - that was what I was referring to.
