Bedding-parallel fibrous gypsum veins, which are widely developed in the Neogene Qingshuiying Formation of the Ningnan Basin, a Tertiary basin located in the northeastern margin of the Tibetan Plateau, provide valuable information on stress field, fluid origin and host rock deformation during their formation.The systematic petrographic …
Hessian fibre-reinforced gypsum, known as fibrous plaster, is a common material used for the manufacture of decorative features, including ceilings and walls in historic buildings, such as theatres and ballrooms, since the mid 19th century. It is still fabricated with modern materials for the decoration of new buildings in the UK, the …
Gypsum occurs in nature as flattened crystals that are often twinned. In addition, it may be found as a transparent, colorless variety with a pearly luster, called selenite.If it is in a silky, fibrous form, it is called satin spar.Alternatively, it may be granular or quite compact.

ABSTRACT Cores from the red beds constituting the Upper Triassic Passaic Formation, a syn-rift sequence in the Newark Basin, display subhorizontal fractures (veins) filled with satin spar gypsum. Such veins are apparent in the shallow subsurface, 100-300 m below present ground level, but are not observed in outcrops or in quarries because of …

Gypsum occurs in extensive beds associated with other evaporite minerals (e.g., anhydrite and halite), particularly in Permian and Triassic sedimentary formations; it is deposited from ocean brine, followed by anhydrite and halite.It also occurs in considerable quantity in saline lakes and salt pans and is an important constituent of cap rock, an anhydrite-gypsum …
Selenite crystals often exhibit a pearly or glass-like luster and have a unique fibrous or columnar structure. The name "selenite" is derived from the Greek word for "moon" due to its moon-like glow when polished or exposed to light. ...
