Geology Branches
Geology is divided into several fields that can be grouped under the main headings of physical and historical geology.
Applied Geology
Applied Geology is geologic knowledge to solving geologic problem. In other words, application of various fields of geology to economic, engineering, water-supply, or environmental problems; geology related to the human activity.
METHODS OF GEOLOGY
Geologists use primary data associated with petrology (the study of rocks), stratigraphy (the observe of sedimentary layers), and structural geology (the have a look at of positions of rock devices and their deformation). In many cases, geologists additionally take a look at contemporary soils, rivers, landscapes, and glaciers; inspect past and contemporary life and biogeochemical pathways, and use geophysical techniques to investigate the subsurface.
Fossils
In paleontology, a fossil is the remains or traces of a plant or animal that lived in the past. Fossils can take many different...
Metamorphic Petrology
Metamorphic petrology is the study of metamorphic rocks, which are rocks that have been transformed from one rock type into another through the action...
Sedimentary Petrology
Sedimentary petrology is the study of sedimentary rocks, which are rocks that form from the accumulation and solidification of sediment. This field of geology...
Igneous Petrology
Igneous petrology is the study of igneous rocks, which are rocks that have formed through the solidification of molten magma. This field of geology...
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...
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...
Petrology Petrology Overview: Igneous, Sedimentary & Metamorphic Rocks Explained
The word petrology comes from the Greek petra (rock) and logos (study or knowledge).In geology, petrology focuses specifically on rocks as aggregates of minerals,...
Paleontology | Fossils, Ancient Ecosystems & Earth’s Long Story
Paleontology is the science that turns rocks into history books. Every fossil—whether it’s a crushed ammonite, a fern leaf flattened between mud layers, a...
Magmatic deposits
Magmatic deposits are mineral deposits that are associated with igneous rocks, such as granite, gabbro, and basalt. They are formed by the cooling and...
Hydrothermal Alteration
What is alteration?Alteration refers to a change in the physical or chemical properties of rocks and minerals. In geology, alteration is a common...
Ore Bearing Hydrothermal Fluids
Ore-bearing hydrothermal fluids are fluids that are enriched in minerals and metals, and play an important role in the formation of many types of...
Fault and Types of Faults
Fault is a fracture or crack where two rock blocks slide past one to another. If this movement may occur rapidly, it can be causes earthquike or slowly, in the form of creep.Types of faults include strike-slip faults, normal faults, reverse faults, thrust faults, and oblique-slip faults.
