WRITTEN EXAMINATION FOR THE POSTS OF PMS OFFICER / AETO BPS-17
(2025)
GEOLOGY (PAPER-I)
Time Allowed: 03 Hours Total Marks: 100
Note:- Attempt any five questions. All questions carry equal marks.
Q.No.1 Discuss the Internal structure of the Earth and critically analyze how the dynamics of lithospheric plates influence major geological processes. (20)
Q.No.2 Explain the origin, characteristics, and geological significance of primary sedimentary structures, and critically analyze how structural features in metamorphic rocks differ in terms of formation processes and tectonic implications. (20)
Q.No.3 Discuss the classification of secondary geological structures with reference to their tectonic origin. How do folds, faults, joints and cleavage contribute to interpreting crustal deformation? (20)
Q.No.4 Describe the morphology and evolutionary history of Foraminifera. Evaluate their geological distribution and significance in biostratigraphy, paleoenvironmental reconstruction, and petroleum exploration. (20)
Q.No.5 Explain the major principles of stratigraphic correlation. Evaluate how these principles are applied to understanding the origin, evolution, and hydrocarbon potential of major sedimentary basins of Pakistan. (20)
Q.No.6 Discuss the formation, texture, and mineralogical characteristics of plutonic and volcanic rocks. How do these features reflect differences in cooling history, tectonic setting, and magma chemistry? (20)
Q.No.7 Examine the major sedimentary environments and associated depositional process. How do variations in energy conditions, climate, and basin dynamics influence the resulting sedimentary facies? (20)
Q.No.8 Provide a detailed account of the principal types of metamorphic rocks. Discuss how temperature, pressure, fluids, and protolith composition control metamorphic mineral assemblages and textures. (20)
