Descriptive Mineralogy
by Bayley, William Shirley

Overview -
This historic book may have numerous typos and missing text. Purchasers can usually download a free scanned copy of the original book (without typos) from the publisher. Not indexed. Not illustrated. 1917 edition. Excerpt: ...where it is slightly pearly. Its hardness is 3.5-4 and density 3.85. In the closed tube it decomposes, yielding water and, at a high temperature, sulphuric acid. It gives the usual reactions for copper and sulphuric acid. Brochantite occurs in the upper portions of copper veins at many places, in some of which it was formed by the interaction between silicates and solutions of copper salts. In the United States it has been found at the Monarch Mine, Chaffee Co., Colorado, at the Mammoth Mine, Tintic District, Utah, and in the Clifton-Morenci Mines, Arizona. HYDROUS SULPHATES The hydrous sulphates comprise a number of sulphates combined with water. Among them are the normal salts mirabilite or glauber salt (Na2S04. 10H20), gypsum (CaSO4. 2H20), the epsomite and melanterite groups (R"SO4. 7H20), chalcanthite (CuS04. 5H20), and the alum group (R'Al(SO4)2. 12H20), kieserite (MgSO4.H20), polyhalite (K.2MgCa2(SO4)4.H20), and a number of basic compounds. Several of them are of considerable economic importance. They are separated into a normal group and a basic group. HYDRATED NORMAL SULPHATES The hydrated normal sulphates occur in crystals, and most of them are found also in beds interstratified with other compounds that are known to have been precipitated by the evaporation of sea water or the water of salt and bitter lakes. All are soluble in water. Mirabilite, or glauber salt, (Na2S04.10H2O) is a white, transparent to opaque substance occurring in monoclinic crystals or as efflorescent crusts. Its hardness is 1.5-2 and specific gravity 1.48. It is soluble in water and has a cooling taste. When exposed to the air it loses water and crumbles to a powder. Mirabilite occurs at the hot springs at Karlsbad, Bohemia and is obtained from the...
