Geology Branches
Home 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.

How Supervolcanoes Work (and What Makes Them Different)
When a volcano erupts, most people imagine a familiar scene: a mountain peak releasing dark ash, bright lava flowing down the slopes, exploding rocks,...
10 Dangerous Volcanoes on Earth

Metamorphic Textures & Fabrics
When a rock enters the metamorphic environment, it begins a slow but profound transformation. Heat increases, pressure rises, minerals dissolve and re-crystallize, grains rotate,...
Textures of Igneous Rocks
When geologists study igneous rocks, the first thing they look at is not color or composition, but texture — the size, arrangement, and relationship...
