Braches of Geology

Geology is divided into several fields that can be grouped under the main headings of physical and historical geology.

Petrology 

Petrology is the study of the origin, composition, and structure of rocks. Petrologists use a variety of techniques to study rocks, including field observations,...

Sedimentology

Sedimentology is the study of sediment and the processes that form and transport it. Sedimentology is an important aspect of stratigraphy because sedimentary rocks...

Volcanology

Volcanology is the study of volcanoes and volcanic processes. It is a subfield of geology that focuses on the physical and chemical processes that...

Structural Geology

Structural geology is the study of the internal structure and deformation of the Earth's crust. Structural geologists use a variety of techniques, including field...

Mineral Deposit

Mineral Deposits Category Mineral deposits are the concentrations of metals or other minerals composed of various geological processes. Our focus is on metals.About half of...

Paleontology

Paleontology is the scientific study of ancient life on Earth. It involves the examination of fossils, which are the remains or traces of ancient...

Stratigraphy

Stratigraphy is the study of rock layers and the layering of rocks. Stratigraphy is an important field because it helps us understand the Earth's...

The Petroleum System

The Petroleum System consists of a mature source rock, migration pathway,reservoir rock, trap and seal. Appropriate relative timing of formation of these elements and the processes of generation, migration and accumulation are necessary for hydrocarbons to accumulate and be preserved.

Hydrogeology

Introduction to Hydrogeology Hydrogeology is the study of the movement, distribution, and quality of water below the Earth's surface. It is a field...

Engineering Geology

Engineering geology is defined by same engineering problems solved to use of application of geological knowladge. Enginering geology understanding of geologic phenomena ,geologic problems...

Field Methods

Field work is a research area for the analysis of information in a laboratory. Field works consist of informal iterviewsdirect observationparticipation in the life the...

Geophysics

The rocks does not differ only by their macroscopic or microscopic properties studied field geologists or petrologists. They also differ by their chemical and physical properties. Hence as the rocks differ according to their origin, structure, texture, etc. they also differ by their density, magnetisation, resistivity, etc. The bad news is that the physical properties do not always clearly correlates with geological classifications and do not necessarily easily translates into the geological terms.
