ASBOG Geology Study Guide 2026–2027 | FG & PG Prep, 200 Practice Questions

Prepare for the ASBOG® National Geology Examinations with a complete study guide built on the current ASBOG® blueprints. Every section follows the eight content domains tested on both the Fundamentals of Geology (FG) and Practice of Geology (PG) examinations: General and Field Geology; Mineralogy, Petrology, and Geochemistry; Sedimentology, Stratigraphy, and Paleontology; Geomorphology, Surficial Processes, and Quaternary Geology; Structure, Tectonics, and Seismology; Hydrogeology; Engineering Geology; and Economic Geology and Energy Resources.

This 148-page digital guide pairs a focused content review with labeled schematic diagrams, quick-reference tables, worked calculations, and two practice tests written at exam level: one weighted to the FG blueprint and one weighted to the PG blueprint, with professional-practice scenarios.

What's Inside

• Exam overview: FG 140 questions and PG 110 questions, 4 hours each, four answer options, computer-based testing at Prometric, scaled score of 70 to pass, fees, and the FG and PG domain weights
• General and Field Geology: map scale and area, UTM, State Plane, PLSS and datums, contours and cross sections, vertical exaggeration, air photos, LiDAR and GIS, seismic refraction, resistivity, GPR, gravity and magnetics, field notes, QA/QC, safety, and ethics
• Earth materials: silicate structures, mineral identification, Bowen's series and igneous classification, sedimentary petrology and diagenesis, metamorphic facies, geochemistry, radiometric decay ages, and hazardous minerals
• Stratigraphy and surface processes: sequence of events, unconformities, sedimentary structures, depositional environments, sequence stratigraphy, biostratigraphy, soils, fluvial, glacial, aeolian, karst, coastal, and volcanic processes
• Structure: Mohr circle, faults and folds, three-point problems, apparent dip, depth and thickness, plate tectonics, earthquakes, and paleoseismology
• Hydrogeology: Darcy's law and seepage velocity, flow nets, Thiem and Cooper–Jacob analysis, capture zones, water chemistry, contaminant transport and retardation, LNAPL and DNAPL, remediation, monitoring wells, sampling, and regulations
• Engineering geology: USCS and Atterberg limits, effective stress, consolidation, shear strength, slope stability, RQD and rock mass ratings, kinematic analysis, liquefaction and other hazards, site investigation, and dams
• Economic geology and energy: magmatic and hydrothermal deposits, porphyry alteration, placers, exploration, resources and reserves, petroleum systems, well logs, Archie's law, coal, geothermal, acid rock drainage, tailings, and reclamation
• Formula sheet and final review checklist, study schedules, FAQs, test-taking strategies, and resources
• 2 practice tests (200 questions) with a separate answer key explaining every answer
