PART - II
Q. 2. Discuss compositional variations between the end members and describe substitutions of the major cations in the feldspars, pyroxenes and olivines.
Q. 3. Discuss the Primary clastic structures in sedimentary rocks.
Q. 4. Explain the relationship between magma chemistry and the production of pyroclastic material and discuss the classification of pyroclastic rocks.
