Stratified rocks were formed from sediments deposited in flat horizontal sheets, but in some places the strata have been warped. See our Privacy Policy and User Agreement for details. Folds vary widely in size; some may be hundreds of kilometers across, whereas others measure just a few centimeters or less. Fig. Fig. Fold and faults 1. Folds and faults obviously have much to do with the selection of dam sites and even such seemingly unimportant matters as the spacing of joints may have vital bearing on uplifting pressure and safety of dams.

In these areas, joints can also be distinguished into dip joints, strike joints and diagonal joints. Duration: 2:08. Geology - Geology - Structural geology: Structural geology deals with the geometric relationships of rocks and geologic features in general. Strata on one side of the joint Meaning of Folds 2. Types of folds. Folds, faults and joints are the main types of structural deformation in the Earth’s crustal rocks. association with faults or folds. It is the branch of geology that deals with: 1. Structural Geology: Deformation and Mountain Building * Figure 10.11a: Fault terminology. also reveal differences in the joint systems at limb and hinge positions on large folds or different distances from large faults. Introduction • Structural geology is the study of factors such as origin, occurrence, classification, type and effects of various secondary structures like folds, faults, joints, rock cleavage and are different from those primary structures such as bedding and vesicular structure, which develop in rocks at the time of their formation.

A joint is a break (fracture) of natural origin in the continuity of either a layer or body of rock that lacks any visible or measurable movement parallel to the surface (plane) of the fracture ("Mode 1" Fracture). Folds. 11. Stike-slip faults are vertical (or nearly vertical) fractures where Rich Dad Poor Dad: What The Rich Teach Their Kids About Money - That the Poor and Middle Class Do Not! Anticline: Upfolds or arches. Joint and faults are often caused by different forces. Although they can occur singly, they most frequently occur as joint sets and systems.

Parts of a Fold 3. Joints are also fractures, but which do not show clear movement of blocks across them. In igneous and metamorphic rocks, the joints may be classified on the basis of their geometric relations with planar structures of those rocks such as lineation or cleavage etc. Meaning of Folds: Ductile deformation of a layered rock forms bends or warps called folds. 7.29). Fold, in geology, undulation in stratified rocks. * * * * * * Figure 10.15b: View of the Humboldt Range in Nevada, which is a horst bounded by normal faults.

With joints, there is no significant movement-related displacement between the two sides of rock, whereas faults are characterized by movement of the two sides of the rock relative to one another. Form, arrangement and internal architecture of rocks 2.
