Seite 48 - Dolomites, magnesites, and magnesian marls have had their origin in sediments of magnesian carbonate formed by the evaporation of solutions of bicarbonate of magnesia. These solutions have been produced either by the action of bicarbonate of lime upon solutions of sulphate of magnesia, in which case gypsum is a subsidiary product, or by the decomposition of solutions of sulphate or chloride of magnesium by the waters of rivers or springs containing bicarbonate of soda.
Seite 217 - By a fossil is meant any body, or the traces of the existence of any body, whether animal or vegetable, which has been buried in the earth by natural causes.
Seite 4 - ... of the lime and sandrocks, or loose water-worn fragments of still older rocks, swept from the north by the current of a universal ocean and deposited during the general subsidence. Some evidences of the direction of these currents were noticed in my report of last year.
