Anhydrite is a relatively common mineral usually formed as a chemical precipitate from saline water in limestone, dolostone, and salt beds. Its presence is obscured by its tendency to dissolve or be altered to gypsum when exposed to groundwater or surface weathering. Its true extent is most often documented in areas that have been drilled extensively during …

The transformation of gypsum into anhydrite at low temperatures under atmospheric pressure as well as at elevated temperatures (150 °C and 200 °C) inside an autoclave was investigated by monitoring changes in both the liquid and solid phases. The effect of temperature, sulfuric acid addition, anhydrite seeding and addition of sulfate …

How to make plants air layer faster. There isn't much you can do to increase the speed at which plants root through air layering, because the main thing you would usually do to speed up the rooting process (increase humidity and aeration) are already taken care of (moss is quite airy plus the plastic keeps humidity in). ...

Gardening experts are increasingly suggesting that plants in the borders don't require much chemical fertilizing – if at all – and that it's more important to feed the soil with organic matter like compost or manure. 'Many gardeners add [chemical] fertilizer out of habit,' says John Porter, Extension Educator at the University of Nebraska-Lincoln.

Anhydrite also occurs as a vein-filling mineral in hydrothermal deposits. It is deposited from solution, often along with calcite and halite, as gangue in sulfide mineral deposits. Anhydrite is also found in the cap rock of salt domes.. Anhydrite is an anhydrous calcium sulfate with a composition of CaSO 4.It is closely related to gypsum, which has a …

Abstract. Alkali in surfactant flooding can sequester divalent ions and reduce surfactant adsorption. When the alkali is sodium carbonate and anhydrite (or gypsum) is present, the anhydrite will dissolve and precipitate as calcium carbonate. An anhydrite level of only 0.1% in the rock is enough to retard the breakthrough of a 1% sodium …
