Questions (page 2)
Q2. (a) Explain the characteristics of crystallographic axes and holding position of crystals belonging to various systems. 15 Describe the changes in mineral assemblages in transformation of basic rocks (b) from greenschist facies to amphibolite facies. What are the typical assemblages of these two facies for the intermediate P-T series?
Q3. (a) Explain diffraction of X-rays in minerals and derive Bragg's law. 15 (b) Diopside-Anorthite binary phase diagram represents a simple binary system with no solid solution. Describe the crystallization behaviour of two melts with compositions equivalent to Di_{90}An_{10} and Di_{25}An_{75} , focussing on the textural differences of the crystallized rocks. 15 Justify the titles of 'pseudocomponent', 'chemographic', |c| 'phase' and 'compatibility' diagrams for AKF diagrams. Show the fields of the following assemblages in AKF diagrams : Muscovite + biotite + cordierite + quartz (i) Muscovite + andalusite + cordierite + quartz (ii) Are these compatible assemblages?
Q4. (a) Draw and label an ideal beach and shoreface cross-section. Discuss the sediment characteristics for each zone. 15 (b) What are the fundamental differences between textures of plutonic igneous rocks and volcanic rocks?
