PMS Geology Past Paper-I 2025
Q No. 1: Briefly discuss the internal structure of the Earth and its composition. How was the thickness of the different internal layers of the earth was estimated?
Q No. 2: How does the theory of Plate Tectonics explain the formation and deformation of the Earth’s crust? Discuss with examples where crust is being created, destroyed, or remains unchanged.
Q No. 3: Discuss the ecological structure of ancient biological communities and the theories of community structures.
Q No. 4: Discuss the Precambrian and Cambrian rocks of Salt Range, Pakistan.
Q No. 5: How does an igneous rock get a porphyritic texture? What characteristic of the silicate minerals in a gabbro makes it so much darker in colour than a granite?
Q No. 6: Differentiate between rare earth and trace elements. Discuss the significance of rare earth elements in understanding the geochemical evolution of the mantle and crust.
Q No. 7: What is Bowen’s Reaction Series (BRS)? How does BRS help predict the order of mineral crystallization and melting, formation of silicate structures (polymerization), evolution of plagioclase composition, and mineral stability at surficial temperatures and pressures?
Q No. 8: Describe the following:
(i) Magmatic ore deposits
(ii) Polymorphism and crystal habit
