What is structure? Any feature produced in rock is structure.

STRUCTURE: STRUCTURE: Features seen in rocks is known as structure. PRIMARY STRUCTURE: Formed at the time of rock formation. SECONDARY STRUCTURE: After rock formation due to movement.

STRUCTURE: A feature produced in rock by movements after deposition, and commonly after consolidation of the rock. STRUCTURE: STRUCTURAL GEOLOGY: STRUCTURAL GEOLOGY: The study of the structural features of rocks, the geographical distribution of the features, and their causes. It is the study of the arrangement or the architecture of the rocks of the earth's crust that has resulted from deformation. It is concerned primarily with the geometry i.e., size and shape of the rocks. Plains, plateaus and mountain ranges are broad features of the earth surface produced by deformation of the earth's crust.

STRUCTURE: A feature produced in rock by movements after deposition, and commonly after consolidation of the rock. STRUCTURAL GEOLOGY: The study of the structural features of rocks, the geographical distribution of the features, and their causes. It is the study of the arrangement or the architecture of the rocks of the earth's crust that has resulted from deformation. It is concerned primarily with the geometry i.e., size and shape of the rocks. Plains, plateaus and mountain ranges are broad features of the earth surface produced by deformation of the earth's crust. The rock that comprise them have certain structural features called folds, faults, joints and unconformities.

SCOPE: Knowledge of structural forms is as important to the geologist as knowledge of anatomy to the physiologist. Knowledge of structural geology is central to our understanding of the earth either as a whole or in its myriad parts. The scope of the field is vast, ranging from the broadest framework of the earth's interior and the major crustal elements to the fine detail of rock fabric. It includes description of the geometry and the spatial relationships of rock bodies on the one hand and the processes by which these relationship come into existence on the other.

SCOPE: Knowledge of structural forms is as important to the geologist as knowledge of anatomy to the physiologist. Knowledge of structural geology is central to our understanding of the earth either as a whole or in its myriad parts. The scope of the field is vast, ranging from the broadest framework of the earth's interior and the major crustal elements to the fine detail of rock fabric. It includes description of the geometry and the spatial relationships of rock bodies on the one hand and the processes by which these relationship come into existence on the other. The crust of the earth is made up of igneous, sedimentary and metamorphic rocks. Of these, the sedimentary rocks are by far the most suitable ones for studying the common types of structures superimposed upon them during epeirogenic and orogenic movements.

TECTONICS: The study of the broader structural features of the earth and their causes. A true understanding of the subject involves a knowledge of:- The physical properties of rocks. The external forces that are applied, transformed or transmitted. The internal stress and strains resulting therefrom.
