Geology is the science of the Earth—its composition, material, processes, history, and the forces operating upon it. A Bachelor of Science in Geology (B.Sc. Geology) is an undergraduate three-year degree that helps students explore the mysteries of the Earth and its natural resources.
If you are considering taking Geology as your major or simply interested in getting to know the structure of the course and topics, this blog will provide you with an in-depth view of what is studied under B.Sc. Geology in three years.
Overview of B.Sc. Geology
Before diving into the subject list, let’s quickly understand what the B.Sc. Geology course is all about.
Duration: 3 years (6 semesters)
Eligibility: 10+2 with Science stream (preferably with Physics, Chemistry, and Mathematics)
Career Paths: Geologist, Petrologist, Paleontologist, Environmental Consultant, Mining Officer, GIS Analyst, etc.
Year-Wise Subjects in B.Sc. Geology
B.Sc. Geology subjects are divided into Core, Practical, and Elective/Allied categories. Each semester includes theory and practical components to provide both conceptual knowledge and field/lab experience.

Texture and structure of metamorphic rocks
Palaeontology – II
Vertebrate palaeontology and microfossils
Evolutionary trends and mass extinctions
Remote Sensing & GIS (Elective/Skill Enhancement)
Basics of satellite imaging and Geographic Information System
Practical IV – Palaeontology & Metamorphic Petrology
Fossil identification
Study of metamorphic textures and structures
Third Year (Semester 5 & 6)
This is the most advanced level where students study applied geology and fieldwork.
Semester 5 Subjects:
Stratigraphy & Indian Geology
Geological time scale
Study of Indian stratigraphic units and their significance
Economic Geology
Mineral resources of India
Ore genesis and mining methods
Hydrogeology
Groundwater exploration and aquifers
Water table, wells, and water management
Practical V – Stratigraphy & Economic Geology
Stratigraphic correlation
Mineral identification and economic uses
Semester 6 Subjects:
Engineering Geology
Geological considerations in construction
Dams, tunnels, landslides, and soil mechanics
Geoinformatics & Field Training
Use of GIS tools for geological mapping
Field trips and report writing
Dissertation / Project Work
Individual or group research project
Data collection, analysis, and presentation
Practical VI – Engineering Geology & GIS
Site analysis for engineering projects
Map interpretation using GIS software
Lab and Field Work
Apart from classroom learning, B.Sc. Geology includes:
Field Trips: Mapping of rock formations, studying structures and fossils
Lab Work: Mineral and rock identification, microscope analysis, model studies
Project Work: Research-based topics under faculty supervision
These components help students gain hands-on experience which is crucial in geology.
Career After B.Sc. Geology
After completing B.Sc. Geology, students can:
Pursue M.Sc. Geology, M.Sc. Applied Geology, or related courses
Appear for GATE, CSIR-NET, UPSC (Geoscientist), or State PSC exams
Get jobs in:
Government research organizations (GSI, ONGC, ISRO)
Private mining, petroleum, or environmental companies
NGOs and disaster management authorities
Teaching and academic fields
Why Choose B.Sc. Geology?
You love nature and Earth sciences
You are curious about how mountains, rocks, and fossils form
You enjoy outdoor learning and exploring new places
You want a career in environmental science, mining, oil and gas, or government sectors
