Polish-Ukrainian seminar “Weathering of gypsum and anhydrite”

The Morphosyntax of Polish and Ukrainian -no/-to

This paper provides a detailed description of the Polish and Ukrainian -no/-to + accusative construction, with considerable attention to how the two constructions differ and to their relevance for current morphological and syntactic theory. It is argued that Polish and Ukrainian -no/-to differ with respect to where the word-final /-no/-to/ affix is generated in the narrow syntax. A wide range o...

Pure dissolution kinetics of anhydrite and gypsum in inhibiting aqueous salt solutions

In the context of the study of the wet creep of plasterboards, we have performed digital holographic interferometry measurements of the dissolution of gypsum of various quarries in water and in aqueous solutions of salts inhibiting dissolution, and of the dissolution of anhydrite in water. This technique is carried out in still water and permits to observe directly the reacting solid-liquid int...

Experimental Shock Transformation of Gypsum to Anhydrite: a New Low Pressure Regime Shock Indicator

Textural pattern of secondary gypsum in the Basal Anhydrite of the Asmari Formation, SW Iran

The Oligocene–Miocene deposits of the Asmari Formation are located in SW of the Zagros Mountains of Iran. The lower part of the Asmari Formation consists of an evaporite bed that is termed Basal Anhydrite. Seven sections from four different anticlines were selected and sampled for petrographic and mineralogical analyses .The petrographical examinations were carried out using an optical polarize...

Rapid Titrimetric Determination of Sulfate in Mixtures of Gypsum, Anhydrite, Calcium Oxide, and Calcium Sulfide Using Ion Exchange

The conventicnal sulfate determination by gravimetrically precipitating barium sulfate is very tedious and time consuming. The present technique uses an ion exchanger so the sulfate can be titrimetrically determined as sulfuric acid. An analysis can be completed in 30 minutes. This method is being used for the routine analysis of sulfate in mixtures of gypsum, anhydrite, calcium oxide, and calc...
