A geologicalfold occurs when one or a stack of originally flat and planar surfaces, such as sedimentarystrata, are bent or curved as a result of permanent deformation. Synsedimentary folds are those due to slumping of sedimentary material before it is lithified. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds. They occur singly as isolated folds and in extensive fold trains of different sizes, on a variety of scales.
Folds form under varied conditions of stress, hydrostatic pressure, pore pressure, and temperature gradient, as evidenced by their presence in soft sediments, the full spectrum of metamorphic rocks, and even as primary flow structures in some igneous rocks. A set of folds distributed on a regional scale constitutes a fold belt, a common feature of orogenic zones. Folds are commonly formed by shortening of existing layers, but may also be formed as a result of displacement on a non-planar fault (fault bend fold), at the tip of a propagating fault (fault propagation fold), by differential compaction or due to the effects of a high-level igneousintrusion e.g. above a laccolith.
Fold is a Unix command used for making a file with long lines more readable on a limited width terminal. Most Unix terminals have a default screen width of 80, and therefore reading files with long lines could get annoying. The fold command puts a line feed every X characters if it does not reach a new line before that point. If the -w argument is set, the fold command allows the user to set the maximum length of a line.
Example
As a usage example, to fold a file named file.txt to have a maximum of 50 characters per line, one could run the following command:
Geology (from the Greek γῆ, gē, i.e. "earth" and -λoγία, -logia, i.e. "study of, discourse") is an earth science comprising the study of solid Earth, the rocks of which it is composed, and the processes by which they change. Geology can also refer generally to the study of the solid features of any celestial body (such as the geology of the Moon or Mars).
The majority of geological data comes from research on solid Earth materials. These typically fall into one of two categories: rock and unconsolidated material.
Country rock is a geological term meaning the rock native to an area. It is similar and in many cases interchangeable with the terms basement and wall rocks.
The term is used to denote the usual strata of a region in relation to the rock which is being discussed or observed.
The following are areas in geology when the term country rock is used;
Intrusive settings; when describing a pluton or dike one may describe the igneous rock as intruding the surrounding country rock, the rock into which the pluton has intruded.
In describing the texture or structure of lit-par-lit (layer by layer) intrusion, the intrusive is described in relation to the country rock or wall rock
Alluvial settings; when describing recent alluvium the material that has arrived through volcanic, glacial or fluvial action can be described as a veneer on the country rock
Geology is a publication of the Geological Society of America (GSA). The GSA claims that it is the most widely read scientific journal in the field of earth science. It is published monthly, with each issue containing 20 or more articles, and an annual total of 1166 pages.
One of the goals of the journal is to provide a forum for shorter articles and less focus on pure academic research type articles.
Overview of Geologic Structures Part 2: Faults and Folds
We just learned about the different types of rock deformation, so now let's get a closer look at some more specific structures. First we have faults, which can be normal, reverse, and strike-slip or reverse faults. We should also take a look at folds, which can be synform or antiform, and syncline or anticline. What do all these terms mean?! I'll show you!

Folds and Faults
For an introductory college-level earth sciences class: a review folds and faults found in Earth's crust: their causes, classification, and importance. Also reviews the various stresses that lead to the variety of deformation types. Includes definitions and modeling of reverse faults, normal faults, and strike-slip faults; anticlines, synclines, domes, and basins; and plastic, elastic, and brittle deformation.

A geologicalfold occurs when one or a stack of originally flat and planar surfaces, such as sedimentarystrata, are bent or curved as a result of permanent deformation. Synsedimentary folds are those due to slumping of sedimentary material before it is lithified. Folds in rocks vary in size from microscopic crinkles to mountain-sized folds.
