Examination Coverage
A. GENERAL GEOLOGY
Covering the Earth as a Planet, Structural Geology and Plate Tectonics Theory, Earth Materials, Earth Processes and Landforms, and Stratigraphy, Historical Geology, Geology of the Philippines and Asia/Southeast Asia
Covering the Earth as a Planet, Structural Geology and Plate Tectonics Theory, Earth Materials, Earth Processes and Landforms, and Stratigraphy, Historical Geology, Geology of the Philippines and Asia/Southeast Asia
Covering the Earth as a Planet: Geologists study the Earth as a dynamic planet, exploring its internal structure, composition, and processes. This includes understanding Earth's formation, its internal layers (core, mantle, crust), seismic activity, magnetic field, and global geophysical phenomena. Knowledge in this area allows geologists to interpret geological phenomena and processes that shape the Earth's surface and influence its evolution over time.
Structural Geology and Plate Tectonics Theory: Structural geology examines the deformation of rocks and the arrangement of geological structures at various scales. Geologists study faulting, folding, fractures, and rock fabrics to understand the forces and processes that shape Earth's crust. Plate tectonics theory explains the movement and interaction of Earth's lithospheric plates, including plate boundaries (e.g., divergent, convergent, transform), seismic activity, volcanic eruptions, mountain building, and the formation of geological features such as ocean basins, mountains, and rift valleys.
Earth Materials: Earth materials refer to the composition, properties, and classification of minerals, rocks, soils, and sediments. Geologists analyze the formation processes, physical properties, chemical composition, and economic significance of Earth materials. This knowledge is essential for mineral exploration, resource assessment, construction materials evaluation, and environmental geology studies.
Earth Processes and Landforms: Geologists study the processes that shape the Earth's surface, including weathering, erosion, deposition, glaciation, fluvial and coastal processes, and mass wasting. They investigate landforms such as mountains, valleys, plains, caves, deltas, and volcanic landforms to understand the interactions between geological processes, climate, and environmental change over geological time scales.
Stratigraphy, Historical Geology: Stratigraphy involves the study of rock layers (strata) and their chronological sequence to reconstruct Earth's geological history. Geologists use principles of stratigraphy, including the Law of Superposition, fossil succession, and correlation techniques, to interpret the age, depositional environments, and geological events recorded in sedimentary rocks. Historical geology examines Earth's past geological events, evolutionary changes in life forms, paleoenvironments, and geological time scales to reconstruct the Earth's history and understand long-term geological processes and events.
Geology of the Philippines and Asia/Southeast Asia: This area focuses on the regional geology of the Philippines and broader Asia/Southeast Asia region. Geologists study the geological framework, tectonic history, mineral resources, geological hazards (e.g., earthquakes, volcanic eruptions), and environmental geology issues specific to these regions. Understanding regional geology helps geologists interpret local geological processes, assess geological hazards, and support sustainable resource management and infrastructure development.
B. PETROLOGY AND MINERALOGY
Covering Chemistry, Crystallography, Physical and Optical Properties of Minerals, Petrographic Techniques, Common Rock Forming Minerals (silicates and non-silicates), Igneous, Sedimentary and Metamorphic Rocks, Identification of Samples of Rocks and Minerals
Covering Chemistry, Crystallography, Physical and Optical Properties of Minerals, Petrographic Techniques, Common Rock Forming Minerals (silicates and non-silicates), Igneous, Sedimentary and Metamorphic Rocks, Identification of Samples of Rocks and Minerals
Chemistry: Chemistry in geology focuses on the composition, structure, and properties of minerals, rocks, and Earth materials. Geologists study chemical elements and compounds present in minerals and rocks, geochemical processes such as weathering and mineral formation, and applications of geochemistry in environmental assessment, mineral exploration, and resource evaluation.
Crystallography: Crystallography examines the internal structure, symmetry, and atomic arrangement of crystals. Geologists use crystallographic principles to identify minerals based on their crystal shapes, symmetry elements, cleavage, and optical properties. Understanding crystallography helps geologists interpret mineral structures, predict mineral behaviors, and classify minerals based on their crystal forms.
Physical and Optical Properties of Minerals: Geologists study the physical properties of minerals, including hardness, cleavage, fracture, specific gravity, luster, color, and streak. Optical properties, such as transparency, refractive index, birefringence, and pleochroism, are observed under polarized light microscopy to identify minerals and distinguish between different mineral species.
Petrographic Techniques: Petrography involves the study of rock textures, mineral assemblages, and structures in thin sections under a petrographic microscope. Geologists use petrographic techniques to analyze rock composition, classify rock types (igneous, sedimentary, metamorphic), interpret depositional environments, assess rock alteration processes, and characterize geological materials for various geoscience applications.
Common Rock Forming Minerals (silicates and non-silicates): Geologists identify and classify common minerals that make up rocks based on their chemical composition and crystal structure. Silicate minerals, including quartz, feldspar, mica, and amphibole, dominate Earth's crust and form the basis of most rock types (igneous, sedimentary, metamorphic). Non-silicate minerals, such as carbonates, sulfides, oxides, and sulfates, also play significant roles in rock formation and mineral resource exploration.
Igneous, Sedimentary, and Metamorphic Rocks: Geologists classify rocks into three main types based on their origin and formation processes:
- Igneous rocks form from the solidification of molten magma or lava. Geologists study igneous rocks to understand volcanic processes, magma evolution, and crustal differentiation.
- Sedimentary rocks result from the deposition, compaction, and cementation of sediments derived from pre-existing rocks or organic materials. Geologists interpret sedimentary rocks to reconstruct past environments, study sedimentary processes, and identify fossil remains.
- Metamorphic rocks form from the alteration of pre-existing rocks due to heat, pressure, and chemical reactions within Earth's crust. Geologists analyze metamorphic rocks to infer tectonic processes, assess crustal deformation, and determine thermal history.
C. APPLIED GEOLOGY
