    same sample. Preserve approximately 25 grams of soilwith 25 ml of methanol in a tared 60-ml vial. A maximum of 35 grams of soil is recommended to enable a 1 1 ratio of soil to extraction solvent in the sample container. Other sample sizes such as 5 grams of soil and 5 mL of methanol in a 40-mL VOC vial can be utilized if the 1 1 ratio is When gypsum loses its water component it forms the mineral anhydrite (CaSO 4). When anhydrite absorbs water it becomes gypsum. This ease of exchange is the basis of gypsum s use in plaster. Consequently the two minerals are very similar to one another and are only easily distinguished by heating a sample in a closed tube.

  • 6. LABORATORY METHODS FOR ANALYSING GYPSIFEROUS SOILS

    The presence of gypsum limits dispersion of soil colloids. In the traditional procedures for particle-size analysis of gypsiferous soils gypsum present in small amounts is leached by using distilled water (Baldwin et al. 1938 Barzanji 1973). Solutions of strong electrolytes can be used to increase the solubility of gypsum and shorten the leaching time (Abrukova and Isayev 1983 Agboola and Evaporitic gypsum deposits represent an important paleoenvironmental record of the Miocene Badenian of the Carpathian Mountains belt.
