What is structural geology PDF?
http://itunes.apple.com/us/book/id1085911016 Structural geology is concerned with the deformation of rocks and rock formations. It is a field-based discipline which aims at understanding, from observation of the landscape and the geology visible at its surface, the 3-dimensional geological architecture.
What are major types of structural features in geology?
Structural geologists measure a variety of planar features (bedding planes, foliation planes, fold axial planes, fault planes, and joints), and linear features (stretching lineations, in which minerals are ductilely extended; fold axes; and intersection lineations, the trace of a planar feature on another planar …
What is meant by structural geology?
structural geology, scientific discipline that is concerned with rock deformation on both a large and a small scale. Its scope of study is vast, ranging from submicroscopic lattice defects in crystals to fault structures and fold systems of the Earth’s crust.
Why is structural geology important?
An essential importance of structural geology is to know areas that contain folds and faults because they can form traps in which the accumulation and concentration of fluids such as oil and natural gas occur.
What are outcrops and why do structural geologists study them?
Structural geologists are required to study outcrops in order to study very small-scale structures in individual rocks. Outcrops are sites where bedrock is covered by vegetation or sediment, thus concealing the structures necessary for study.
What is structural geology and rock mechanics?
The studies identify the structural characteristics and properties and the 3D geometry of the bedrock in the target area, the stability of the bedrock and water flow in bedrock fractures. The services are divided to two sub-areas.
What is the difference between structural geology and tectonics?
The difference between structural geology and tectonics is that structural geology deals predominantly with the study of small scale deformation, from sub microscopic to regional. Tectonics deals with deformation on a global scale, for instance at the level of a whole region or a continent, or a whole plate.
What is structural geology essay?
It is the study of permanent deformations and rock failure created due to the changes in stress through geologic time. The processes that result in the formation of geologic structures and how these structures affect rocks are studied in the structural geology.
What is a tectonic structure?
a regularly repeating form of occurrence of rocks in the earth’s crust. In the broad sense, the term “tectonic structure” is applied to various parts of the earth’s crust that are formed by the combination of a number of different smaller structural forms.
How are geologic structures related to plate tectonics?
Geologic structures are usually the result of the powerful tectonic forces that occur within the earth. These forces fold and break rocks, form deep faults, and build mountains.
What does the term tectonics mean?
Definition of tectonics 1 : geologic structural features as a whole. 2a : a branch of geology concerned with the structure of the crust of a planet (such as the earth) or moon and especially with the formation of folds and faults in it.

What is the tectonics of the Earth?
INTRODUCTION TO TECTONICS. The Earth is composed of layers of different composition and physical properties, principally the solid central core, the fluid peripheral core, the viscous mantle, and the solid . The lithosphere lithosphere is comprised of the upper mantle and the crust, the outer shell of the Earth.
What is the study of plate tectonics?
Tectonics is the study of the origin and arrangement of the broad structural features of Earth’s surface including: ● Earthquake belts The basic premise of plate tectonics is that the Earth’s surface is divided into a few large, thick plates that move slowly and change in size.
What are the major concepts of geology?
Geology 200 Geology for Environmental Scientists Major Concepts •Foldsin rocks range from microscopic to hundreds of kilometers across. • Faults are fractures along which displacement has occurred. •Jointsare fractures where there has been no displacement. • Rocks deform when applied stress exceeds rock strength.
When did the theory of plate tectonics start?
THEORY OF PLATE TECTONICS The theory of plate tectonics originated in the late 1960’s by combining two pre-existing theories: Continental Drift– The idea that continents move freely over the Earth’s surface, changing their positions relative to one another
