Mention some of the more commonly occurring minerals, or rocks, of which Lime forms an essential constituent. 4. What reagents are used in operations before the blowpipe, and state how they assist in the determination of metals or metallic oxides? Give examples. 5. Name the metals which occur in a native state, and arrange them under their respective crystalline systems. 6. By what characters (including cleavage) are Quartz, Calcite, Selenite, and Topaz distinguished? 7. Name three minerals belonging to the Cubical (Monometric) System, each of which has a different cleavage. 8. Give examples of Saline, Combustible, Earthy, and Metallic minerals, and state how they can be distinguished from each other. 9. Mention the general characters and composition of Zeolites,' and in what rocks are they most usually found. 10. Describe the mode of occurrence of Coal, and the associated strata, in the Coal measures. 11. Name twelve genera of fossil shells, and rep tiles which are commonly found, or considered characteristic of, the Secondary or Mesozoic strata. 12. What is the geological position of the 'Eocene" strata, give the subdivisions of the Eocene strata, and their geographical distribution in England? 13. Name any three geological formations, and mention some of the most characteristic fossils found in them. 14. Give a general geological description of any county or district in England, with which you are acquainted. 15. Describe the geological or mineral characters of the chalk formation, and name the genera of fossils of common occurrence. 16 Define the terms: Break in Succession, Synelinal, Geode, Anticlinal, Unconformable, Stalactite, Porphyry. 17. What metals are obtained from the following minerals Malachite, Blende, Cassiterite, Chaly bite, Hematite, Cinnabar, Wolfram, Galena, Cuprite, Pyrargyrite, and with what substances are the metals combined in each mineral? MINERALOGY AND GEOLOGY. HENRY W. BRISTOW, F.R.S. 1. State in what respects Mineralogy and Geology agree and differ. Show the importance of a practical knowledge of those Sciences, more especially to military men. 2. Give a definition of a Crystal. Explain the object of Crystallography. 3. Describe the method of determining the specific gravity of a compact mineral. Show the importance of a knowledge of the specific gravity in the identification of minerals. 4. How is the presence of arsenic in minerals readily detected? 5. Name and describe the ore of lead in which silver is commonly found. Name some of the British localities from which such argentiferous ores are most abundantly obtained. 6. What is understood by the polarisation of light? Name the minerals which are chiefly employed for showing the phenomenon in question. 7. Explain how Gold may be distinguished from Brass, Copper Pyrites, Iron Pyrites, and Mica. 8. Write a list of the British Palæozoic strata, with their subdivisions in the order of their ages, beginning with the newest. 9. Explain the mode of formation of Septaria. Name the class of rocks in which they usually occur. 10. In what rocks do bituminous shales mostly occur? State the purposes to which they are usefully applied. 11. What is meant by an aqueous or sedimentary rock? Describe the ways in which such rocks have been formed? 12. In what rocks is cleavage most likely to occur? For what economic purposes are cleaved rocks employed? 13. What is Gravel? State the advantages of living on a gravelly soil. 14. Give the composition of ordinary limestone. Describe a ready mode of testing such stones. 15. Describe Volcanic Bombs. Explain their origin and mode of formation. |
