Some of the large vugs
seen are introduced by the removal of a small fraction of the ooids from the primordial deposit.
The studied carbonate rocks contain numerous vugs
and fractures (Fig.
5 m thick tan bed that lacks lamination and contains a very porous surface full of vugs
and bird's-eye structures.
The more soluble components, first of all limestone clasts, gypsum, and halite crystals, were dissolved and vugs
were formed in the rocks (Fig.
(1-2 mm), formed as a result of dissolution of carbonate fauna, are found.
Three to 10% open spaces as crusty vugs
contribute to the rock's porous, crusty texture.
is often cracked and includes vugs
and stretches filled with crystalline dolomite or calcite.
104 Quartz- local vugs

25 crystalline dolomite with brownish spots and occasional vugs

The earliest Jurassic (Hettangian) North Mountain Basalt of the Bay of Fundy has long been known for its rich assemblage of zeolite minerals in amygdales, vugs
, and fractures (Aumento 1966).
Loosely held native gold is observed in open-space fractures and in vugs
within late-stage breccias.
The MFU is characterized by a systematic zonation of zeolites occluding primary vugs
