Sabkha and Desert Features

2018-6-1The pure gypsum within nodules is known as alabaster and is used for carving. Enterolithic veins are over-developed displacive nodules of white soft gypsum or anhydrite which have burst out and pushed on into the associated soft sediment of a sabkha (West, 1965) . They commonly occur approximately parallel to the sediment surface, although in

The origin of large gypsum crystals in the Geode of

The Geode of Pulp (Almera, Spain) is an ∼11 m 3 ovoid cavity, the walls of which are covered with meter-sized idiomorphic and highly transparent gypsum (CaSO 4 2H 2 O) crystals. We performed a thorough study based on field work, and petrographic and geochemical data collection, which aimed to reconstruct the geological history leading to the formation of this

Gypsum

I INTRODUCTION. Gypsum is a widely occurring mineral that has been used for many years as a soil conditioner and ameliorant for sodic and heavy clay soils and as a nutrient source of Ca and S for plant growth (Shainberg et al., 1989). However, recent research has shown that the utility of gypsum can be extended to acid, infertile soils as an

False Ceiling : Definition, Benefits and Various Types

2021-2-24Gypsum is the most commonly used false ceiling material. The panels come with either tapered or square edges. Gypsum boards can be easily fixed either by nailing directly to ply or other plain surfaces or placing on a galvanised iron (GI) metal grid. Gypsum board comes in standard sizes of 6 feet X4 feet and 8 feet X 4 feet.
